 * 20x faster charging for new EV battery  from Power Japan Plus


Engineering company Power Japan Plus has developed a new battery suitable for electric vehicles, which offers faster recharging, longer lifespan and improved safety with no cost increase.


Designed with the Kyushu University in Fukuoka, Japan, the Ryden dual carbon battery uses anodes and cathodes made of carbon and an organic electrolyte, which removes the need for rare earth materials and thus reduces cost and environmental impact, as well as avoiding price fluctuations.


The Ryden dual carbon battery offers improved charging times, durability, safety and environmental performance, according to Power Japan Plus


It offers the same energy density as a lithium-ion battery, but with significant improvements in charging capability. Power Japan Plus says the battery can charge at 20 times the rate of current generation units and, unusually, can be 100% charged and discharged without becoming damaged.


Removing the need for unstable active materials also reduces the fire and explosion hazard, and the units are 100% recyclable at the end of life, the company said. The technology will be licensed to existing battery manufacturers to bring it to market, not only in large applications such as electric vehicles, but for smaller industries such as medical supplies and satellites.

Coda Energy betting on building energy storage!?

Last year we covered the bankruptcy of venture-capital-backed EV maker Coda, and the plans of its new owner to resurrect it as a grid battery systemsprovider. Now we’re seeing the fruits of that plan emerge, in the form of yet another no-money-down energy storage play -- this one financed internally by Fortress Investment Group (FIG), the multi-billion-dollar investment firm that picked up Coda’s assets for $25 million in June.

Over the past month, Coda Energy has quietly installed about twenty of its “CODA Core” Tower systems at commercial and industrial sites across California, and it has also secured financial backing from its parent company for a total of 100 systems over the next few months, John Bryan, vice president of product and marketing, said in a Monday interview.

At $64,000 for each 30-kilowatt, 40-kilowatt-hour, lithium-ion-battery-based, inverter-integrated unit, that adds up to a $6.4 million commitment from Fortress -- and under the terms of its financing model, the customers pay nothing, he said.

Instead, “we’ll pay for it, no payments at all for the first year, and the nine following years, we’ll split the difference in savings with the end user,” he said. In other words, Coda's customers will pay only 50 percent of whatever savings the systems provide to annual utility bills, rather than a set payment -- an offer that puts the onus on Coda to achieve high enough savings to pay back its system installation and maintenance costs over the term of its ten-year-warrantied lifespan and beyond.

If the first 100 projects appear on their way to proving that this revenue stream represents a workable model, Fortress is considering expanding the program to include 400 installed systems, representing $25 million in financing for a combined 12 megawatts/16 megawatt-hours of storage capacity, he said.

That could put Coda Energy on par with Stem, the startup that in Octoberlaunched a $5 million financing program with Clean Fleet Investors to drive 15 megawatts of building-integrated battery systems, and Green Charge Networks, which last week announced its own $10 million financing deal with TIP Capital meant to bootstrap 5 megawatts of installations by year’s end.

It also puts Coda in a position to challenge SolarCity and Tesla in their bid to create the country’s largest fleet of behind-the-meter storage systems. The companies have been piloting battery-backed solar systems in homes for the past two years, and in December they launched an energy storage financing program targeted at PV-equipped commercial buildings, with a target of 30 megawatts to 50 megawatts of installations this year.

Reducing demand charges (the portion of a commercial building’s utility bill that accrues whenever electricity usage exceeds a set amount) is the primary economic driver for these battery systems. In markets such as California and New York, ever-rising demand charges can add up to more than half of a commercial customer’s utility bill. By metering building energy use, anticipating when it’s about to peak, and injecting stored battery power to prevent it, demand charges can be nipped in the bud.

That requires more than a battery, of course. For its no-money-down energy tower systems, Coda Energy has partnered with inverter maker Princeton Power to convert battery DC power to building-ready AC, and has designed the software that manages the charging and discharging of the system in response to building load metering, Bryan said.

 Grid Scale Battery business alive ? :interesting

Wanxiang backs post-bankruptcy push into new megawatt-scale international contracts and new energy-centric systems. 

Grid-scale batteries are a hard business to break into -- and a hard business to regain market share lost to the competition. But for A123 Systems, it appears that Wanxiang Group, the Chinese company that bought it out of bankruptcy two years ago, has been serious about keeping its grid energy storage businessalive.

That’s one impression to take from a slew of contracts announced by A123 Energy Storage Solutions in the past month. First came news from China, where the non-automotive arm of A123 announced its 2-megawatt battery was in commercial operation delivering frequency regulation services for Beijing-based Ray Power Systems Co. Ltd.. It’s A123’s first such project in China, although the firm's batteries are being used for similar fast-reacting, power-centric applications by AES Energy Storage in the United States.

Then, A123 announced two more contracts, using its new Long Duration Grid Battery System, developed to emphasize multi-hour energy storage, rather than quick-burst power density, as a core attribute. The first is a 1-megawatt, 3-megawatt-hour system for Spanish Transmission System Operator (TSO) Red Eléctrica de España (REE), delivered as a turnkey solution to integrate renewable generation to the grid while providing reactive power, frequency regulation, and voltage regulation.

The second 1-megawatt, 2.8-megawatt-hour system, announced last week, is capable of similar services, but for a corporate customer. That’s Japanese manufacturer IHI Corporation, which wants to manage its peak power demand and integrate on-site large-scale solar PV at an IHI factory in the Tohoku region of Japan, the northern section of Honshu Island that’s still struggling to meet electricity needs in the aftermath of the 2011 Fukushima disaster.

These aren’t huge new contracts, compared to some of the projects being announced from lithium-ion battery contenders like BYD, Mitsubishi, Panasonic, Samsung, LG Chem, Johnson Controls and Saft. Indeed, they're small compared to A123's 110 megawatts of batteries already deployed, in projects like the 32-megawatt array backing AES’s Laurel Mountain wind farm, in Chile's Atacama Desert, or on the Hawaiian island of Maui.

But they do represent important proving points for a business that lost some significant contracts during its bankruptcy, including a project in Chile with AES Energy Storage and an 8-megawatt, stimulus-grant-funded project with Southern California Edison. What’s more, A123’s launch of its long-duration storage system indicates that Wanxiang is serious about investing in products that take on a core challenge for lithium-ion batteries in grid-scale applications.

“The long-duration system is actually a completely different energy storage cell” than the company’s previous “high-rate” systems, although it uses the company’s same lithium-iron-phosphate chemistry, Roger Lin, director of product marketing for A123 Energy Solutions, told me in a January interview. Specifically, while its high-rate systems are built with its 26650 cylindrical cells, the long-duration batteries are built with its AMP20 prismatic pouch cells, the same that are being used for electric vehicle customers like General Motors for its Chevy Spark, he said.

These prismatic cells, stacked together into storage racks and integrated into formations suitable for supporting grid-scale tasks, can add up to 4 megawatt-hours of storage within a 53-foot storage container, he said. Lithium-ion has so far been seen primarily as a “power” application, unsuited for long-term energy storage or shifting, as compared to competing technologies like sodium-sulfur batteries, flow batteries or emerging aqueous electrolyte-based metal batteries.

A123 is supplying more than batteries, he added. “We have a stable of inverter providers that we use,” he said. “We do all of our own controls hardware and software internally. That includes battery management systems for the cells, and at the highest level, overall control systems for the battery solution.” That’s an important distinction in the emerging grid-scale battery industry, where makers of battery chemistries now in active grid deployment (lithium-ion, sodium-sulfur, advanced lead-acid) are both equipment suppliers and key partners in integrating their products into grid-ready configurations.

So far, A123 has focused on containerized systems, but it’s also looking at launching smaller-scale, behind-the-meter applications in the next year or so, he said. GTM Research predicts that customer-sited energy storage could be one of the first applications to break the economic barriers -- namely, the high price of batteries -- that have held them back from serving more roles on the grid.

Today’s grid battery applications include a few niches, such as frequency regulation, or using it to reduce peak stress on substations or transmission lines that would otherwise require expensive renovations. But future applications, like smoothing out renewable energy’s grid disruptions, shifting energy loads from off-peak to peak demand hours, will require both cheaper batteries and more sophisticated control and integration to put them to multiple uses.

Whether or not grid-scale energy storage can actually meet these needs in the short to mid-term is much-debated question in the industry. Moves bygrid regulators in California and other important regions to mandate grid storage or create energy market mechanisms for it could help. At the same time, the recent bankruptcy filing of Xtreme Power highlights the challenges still facing grid-scale battery vendors as they seek to capture projects in a slow-growing, untested market.

On the cost side, there’s no doubt that lithium-ion batteries are quickly falling in price, based on the rapid growth in manufacturing supporting their rollout in consumer electronics and electric vehicle applications. Lin estimated that today’s multi-megawatt lithium-ion systems are being priced at about $800 to $1200 a kilowatt for an hour of storage for AC systems -- quite a bit cheaper than some of the project costs cited in industry reports from a few years ago.

At the same time, “Cell costs for long-duration systems can be up to 50 percent to 60 percent for some of the four-hour systems out there, but it’s not the whole picture. Close to 30 percent of the cost comes from balance-of-system” components, he noted. “While cell costs have come down, that balance-of-system cost cannot be ignored -- and it’s the systems integration that can start to really squeeze those costs down.” courtesy GTM

KAIST EEWS Graduate School Professors Choi Jang-wook and Lee Jeong-yong, and Professor Kim Taek-soo of the Mechanical Engineering Department, announced they have successfully developed a new concept battery that can be bent, folded, and charged with solar power.

Recently, with the release of Samsung’s Galaxy Gear, Apple’s iWatch, and Google’s Google Glass, technological competition is rising for domination of the wearable device market. 

The research team focused on applying flexibility to batteries based on fabric used for clothes, and how it doesn’t change regardless of repeated movements.

First, polyester fabric was plated with nickel. Then as an electrode active material for each pole, a thin layer of lithium-phosphoric acidic iron oxide on the positive side, and lithium-titanium oxide on the negative side have been coated for a flexible collector. This collector maintains the fabric’s flexibility, allowing bending, folding, and wrinkling. This improves on the original battery collector made of aluminum and copper, which easily broke after a few bends. 

In fact, the three-dimensional fabric structure used as the collector’s frame allows power to be distributed equally regardless of repetitive movements, making the battery function smoothly even after folding 5,000 times. The collector will soon be applied to various wearable sectors after a future optimization process, such as showing 2V voltage and 85mAh capacity.

A battery that never goes dead. Has the Israeli company Sol Chip found the way to do it? The Haifa-based company has developed a new solar battery for mobile electronic devices that might never need to be recharged manually. Operable in sunlight and low-light environments, the batteries are a result of the cross pollination of solar cell and microchip technologies.

“The company offers the missing technology that will improve batteries’ life or, in many cases, eliminate the need for a battery as a power source in low power applications,” says CEO and founder of Sol Chip, Dr. Shani Keysar.

“The idea is that chips need power, so why not give them the power directly anyway?” Keysar tells NoCamels. Prior to Sol Chip, she had extensive experience as a researcher at the Technion, and later spent 15 years in the semiconductor industry. It was during the latter years that the idea for a solar battery was conceived, from her initial research on how solar energy can be used to combat growing pollution levels from Haifa’s many industrial companies.

The company’s current product is limited to an output of 8.4 volts of power. Though it is considered a relatively low output, it can provide power for a vast array of outdoor devices. As a first step, the company has been working on adapting the solar batteries into sensors that are used widely in fields of agriculture, farming and weather testing, as well as security related applications.

A farmer’s market

The solar chip

One market Sol Chip is hoping to tackle is the milking industry. Monitors are often attached to cows in order to gather information about the animal and ensure milk quality. However, these sensors currently run on batteries that need to be replaced. Sol Chip says its battery could be a cost-effective and ecological replacement.

Sol Chip is already working with Netafim, an Israeli company that specializes in drip irrigation technology for agriculture, to replace the batteries on their drippers with the solar battery. The primary benefit of using Sol Chip’s solar batteries is obvious: maintenance cost savings to customers in the long run as it eliminates the expensive costs incurred to replace batteries. If a farmer needs to replace a battery on an outdoor sensor at present, he has to send the unit to the factory or hire the services of a technician to go into the field to replace it. Both methods are expensive.

Although solar cells have been around for a long time, and microchips have been the mainstay of electronic devices, Sol Chip claims that there has been no known company in the semiconductor industry that has successfully integrated solar cells within the standard chip manufacturing process in a cost-effective way. Achieving this goal requires deep understanding and experience of semiconductor manufacturing processes, and Keysar had the advantage of being very well versed in those processes.

Sol Chip unveiled their flagship solar battery in April of this year at the International Conference and Exhibition in Berlin, the world’s leading energy harvesting conference.

Small team, long reach

While the company’s manufacturing technique is patented, it is not without its share of competitors. The company’s closest competitors are those that manufacture small solar cells. Although the solar cells serve the identical function of producing electricity from light, Keysar claims that the solar battery’s advantage is that it can provide output in many different voltages, something existing solar cells cannot do.

The startup is targeted primarily at the North American and European markets. “It is easy for us, because we already have the connections and people in those markets,” says Keysar.

Sol Chip’s main clients will be the hardware integrators that develop and supply sensor systems for agriculture, farming, and defense security. Although the staff headcount is small (currently at six), it has already cast its nets globally. Besides a network of representatives in Europe that help to promote Sol Chip’s presence, the company has also stationed a permanent marketing director in Canada. In the years to come, Keysar intends to expand the reach of the company towards the Far East, as well as India.

With $2.5 million raised so far from the Office of the Chief Scientist, Sol Chip has dedicated most of the money towards R&D. The company is also looking to raise additional funds in an upcoming Series B financing round, to offset R&D and product qualification costs for the next generation of solar batteries it is working on. “The next generation solar batteries will have power management built into the batteries to make energy collection more efficient,” says Keysar.

Most battery advances concentrate on improving hardware, but researchers from the University of California San Diego have developed new algorithms that can cut lithium-ion battery charge times in half.


Usually battery behaviour is tracked by monitoring voltage and current, but according to the researchers relying on those measures leads to over-designed, oversized batteries that weigh and cost more. Instead, the San Diego researchers have been developing complex algorithms that can estimate where lithium ions are within cells to more accurately predict battery health. source

Rechargeable Batteries Could Get New Life

Now that researchers know that nickel blocks lithium ions and keeps older batteries from recharging, they can try to modify manufacturing processes to avoid the problem.

Lithium-ion batteries have layers of material sandwiched together. The scientists engineered each layer into paint and then sprayed each one on to create a battery.

Energy storage innovation key to solar advancement

There is little innovation happening in the renewable energy storage field, according to the report. Of 162 US patents issued for solar energy in the first quarter of 2012, only two dealt with energy storage. But there are likely other companies working on solutions, Vyakaranam said.

“Apart from solar energy companies with R&D facilities, storage innovation could also be expected from companies with pioneering research in other areas,” Vyakaranam said. “Companies dealing with advanced batteries and ultra capacitors are the important examples. There are a number of universities and research organizations with extensive research on fuel cell technology and Hydrogen-based energy storage systems, both of which can complement a solar power plant if there is a breakthrough in efficiency and cost.”

He said major energy companies like GE Energy and several battery companies are also doing research to see if battery storage could become more efficient and affordable.

“Currently, as solar energy is close to achieving grid parity in some locations, solar adoption is already increasing steadily,” Vyakaranam said. “However, a commercial storage technique would boost solar adoption in countries where there is excessive and intermittent generation of energy due to renewable energy sources like solar and wind.” more 28/6/12

* University (WSU) has developed a technology that can triple the capacity of lithium ion batteries. As they will be able to last three times as long, you will be able to take your gadgets that much farther without having to hunt for charging points.Uttara Sahaym and Dr Grant Norton of the WSU, along with a team of students, have devised the battery in which tin — when used as the anode — has the capability to increase the storage capacity by three times, compared to ones that use carbon for the purpose. The new tin anode can store almost three times the energy.

Battery-Powered Buses Enter the MainstreamBetter lithium ion batteries have led to an explosion in availability of plug-in passenger cars. And now, thanks to relatively cheap electricity and the simplicity of the electric drivetrain, electric vehicles have even more potential for use in the extremely cost-sensitive public transportation arena—a concept that is only just taking root. Lithium ion batteries are still not energy dense enough hold more than the equivalent of between four and eight liters of gasoline in a battery package small enough to put on a bus. Nevertheless, inherent efficiencies in the electric drivetrain enable significant increases in fuel economy. Whereas a typical 12-meter-long, diesel-powered transit bus might return between one and two kilometers per liter, the electric ones that Foothill is running average the equivalent of 8.5 kpl. After some quick math it is apparent that 8.5 kpl combined with 7.5 liters of energy storage is not enough to fuel the hundreds of kilometers a bus might need to travel in a day. To get around this, both Foothill and LINK have added ultrafast charging stations in the middles of their buses' loops. source

 providing information on how electricity storage and grid integration can be combined to ensure solar power is used effectively by those who generate it. The program also provides the opportunity to take an electric vehicle for a test drive in the outdoor exhibition area of Messe München, allowing visitors to experience the future of mobility first hand.

E-mobility and solar power
These intelligent systems are the most effective and sustainable when the vehicles are "filled" with solar power from, for example, the energy produced by the user's own roof-mounted PV installation or carport. In addition to protecting cars from rain and snow, PV carports are also able to deliver the energy needed for e-vehicles. Part of the solar power is used to charge the vehicle battery, while the rest is consumed for a different purpose or fed into the grid. Special charging stations for PV carports synchronize the charging times of the electric vehicles with electricity generated by the photovoltaic installation. An installation with a capacity of three kilowatts (kW) can supply enough power for a vehicle to travel around 15,000 km per year. The combination makes sense because electric vehicles have significantly greater levels of efficiency than vehicles with combustion engines, and generating power from renewable sources is much more efficient than producing biofuel for example. source  11/6/12

Cars can be turned into backup generatorsPower inverters on the market connect to car batteries to keep home appliances running. Just pop the hood, connect the inverter directly to the battery of a running car and thread the power cord from the inverter into the house. A refrigerator, television, lights or other devices that usually plug into a wall outlet would instead connect to the inverter power cord.

PowerBright, based in Coral Springs, Fla., makes inverters in a variety of power configurations. A 900-watt version, costing about $60, is strong enough to run a sump pump, freezer or refrigerator, and it can handle the peak power surge from first plugging in a refrigerator, Chief Executive Gil Hetzroni said. A 2,300-watt version, Hetzroni said, can power many appliances at the same time.

Power inverters work with gas-powered cars as well as electric vehicles, but Nissan Motor Co. and Toyota Motor Corp. have both developed equipment specifically for electric cars. The bi-directional electric vehicle charger, which Nissan calls the Leaf to Home electricity supply system and Toyota dubs V2H for vehicle-to-home charging system, can reverse the flow of electricity from electric car to house in case of blackouts.

"The design is ergonomic and very convenient to use. One hour of direct sunlight is enough to charge a mobile phone for one hour talk time," said Suren Vikash, the brain behind the bag. 
'' By looking at different ways to manage waste at source and by understanding how the existing system works, we understood how intervention at various points with small changes would result in big differences. We decided to make useful products from waste by providing value to otherwise discarded material . We use waste as rich raw material to innovate.

Energy storage: Could hydrogen be the answer?

* Batteries that store solar power for use at night !

Jerry Martin, CEO and cofounder of a small startup in Colorado, says his company—Boulder Ionics—is developing a way of making a type of electrolyte that would enable high-performance batteries.

Ionic liquids are normally expensive to produce, but Boulder Ionics is developing a cheaper manufacturing process.

Replacing conventional electrolytes with ionic liquids could double the energy storage capacity of ultracapacitors by allowing them to be charged to higher voltages. That could make it possible to replace a starter battery in a car with a battery the size of a flashlight, Martin says.

The electrolytes could also help improve the storage capacity of lithium-ion batteries, the kind used in electric vehicles and mobile phones; and they could help make rechargeable metal-air batteries practical. In theory, such batteries could store 10 times as much energy as conventional lithium-ion batteries.

Kyocera to Launch Solar With Li-Ion Battery Storage for Homes in Japan

The system will include Kyocera’s solar energy equipment, including solar panels, inverter and software to monitor and manage energy use, with lithium-ion storage and inverter from Nichicon Corp. The battery storage, at 7.1 kilowatt hours and weighing about 200 kilograms, will feature lithium-ion cells from Samsung. 

This will be an ideal product for india. 

Kyocera said it has developed hardware and software to control the charge and discharge of solar electricity and manage that supply and demand for both feeding the solar electricity into the home or the grid.

A storage battery like this will be very useful in INdia.

Kyocera and Nichicon said they are rolling out this new system because of demand for residential backup power supply following the Fukushima nuclear power plant disaster nearly a year ago. That disaster also has prompted the Japanese government to promote more renewable energy generation. Last August, it approved a plan to introduce feed-in tariffs for various types of renewable power, though it didn’t plan on deciding what the tariffs will be until this year. more

aleo solar AG is to present two solar power storage systems at Intersolar (Hall A3/Stand 380): the Voltwerk VS 5 Hybrid and the S10 from E3/DC are suitable for family homes and small businesses.

Both these storage solutions can cover a large proportion of direct electricity demand (70 to 80 percent). The solar power is consumed directly as required, stored in the battery or fed into the public grid. This enables operators of photovoltaic systems to become more independent from suppliers and from rising electricity prices. “With optimum configuration, the storage systems are now a worthwhile addition to existing and new systems,” says Jörn-Bo Hein, Head of Sales Germany.

Both systems are DC coupled, fully integrated, and designed to last for up to 20 years. They are based on sophisticated lithium-ion storage systems including battery management, an inverter without transformers and a monitoring system. Monitoring is possible via an Internet portal or iPhone app. The mix of mains current, battery power and solar power is managed fully automatically and conveniently – operators do not need to modify their consumption behaviour.

The VS 5 Hybrid from the German manufacturer Voltwerk (Bosch Group) is available with a capacity of 8.8 kilowatt hours (kWh), 11 kWh or 13.2 kWh. The system ensures the greatest possible proportion of directly consumed electricity, even when consumption is high or fluctuates sharply. The electricity consumption data for a household, the status and efficiency data for the photovoltaic system and the battery are represented in real time. A further function of the VS 5 Hybrid is that it offers the best possible security of supply even in the event of a mains power failure. Voltwerk offers a five-year warranty on the whole device.

The S10 from the German manufacturer E3/DC is integrated into the home electrical network at the home junction box, so there is no need for electrical modifications to the home network or room ventilation systems. An additional USB wireless module allows straightforward integration into a home automation system. The capacity of the S10 is 5.4 kWh and this can be increased up to 10.8 kWh. E3/DC offers a six-year manufacturer's warranty on its “powerstations”. As a sales partner, aleo solar has concluded a cooperation agreement with the manufacturer E3/DC.

Did you know that the sun gives off approximately one thousands watts of power per square meter per day? If we could pull all of that energy together and store it, we would have an infinite amount of energy available to power the entire world. But we haven�t yet invented a device to do that. We have at present solar cells that capture a small portion of the energy and stores it for future use. A solar battery stores the sun�s energy and discharges it for future use. Solar cells can be found almost everywhere � in calculators, on satellites and now on the roofs of many new homes.

But what are these cells made up of? Small photovoltaic cells or modules (groups of these cells) are displayed on a large frame and directed at the sunlight. These cells are made up of silicon semiconductors, which will absorb part of the light and convert it into energy by shaking electrons loose and allowing them to run along the semiconductor. The current then runs through the metal contacts at the top and bottom of the PV cell and can be used to power anything from a small calculator to an electricity grid. Or it can be stored for literally a rainy day, which is where solar batteries come in. 

The solar-generated energy, the electricity is most often fed into the electricity grid using inverters (grid-connected photovoltaic systems); in stand-alone systems, batteries are used to store the energy that is not needed immediately. Solar panels can be used to power or recharge portable devices. 


These batteries are called deep-cycle batteries and are very different from other batteries. The two types of deep-cycle batteries in common usage are lead-acid batteries and nickel-cadmium batteries. Nickel-cadmium batteries have a longer life and you can technically empty them totally without any bad effects on the battery or any problems recharging them back up to full capacity. On the other hand, lead-acid batteries should not be emptied more than halfway as it would affect their lifespan Lead acid batteries are much cheaper than nickel cadmium batteries. A charge controller needs to be installed to make sure that your solar batteries aren't being overcharged by a bright sunny day or drained to the point of destroying the battery's potential to hold a charge. The power coming in will be DC or direct current. This needs to be converted to AC or alternating current in order to be compatible with most of our household needs. 

An inverter will convert the DC current to AC current. This system can be relatively self-sufficient once it goes into operation, with maintenance being the only concern and monitoring the wear and tear on the solar batteries. At the present it is uneconomical as the cost of renovation is about $30000. 


A solar battery must be able to provide long periods of deep discharge each evening and night, followed by a full recharge during the day. 1 Some solar battery banks use wet cells 2 gel cell batteries, and each have different temperature, mounting, and ventilation requirements. The wet battery has acid and water in it as a solution, whereas in the gel cell battery the acid is immobile and resides in special gelified webbing. The gel batteries do not need to be kept upright (though they cannot be charged inverted), there is no electrolyte evaporation or spillage (and subsequent corrosion issues) common to the wet-cell battery, and they have greater resistance to extreme temperatures, shock, and vibration. 

The gel cell battery is designed to be run flat repeatedly and recharged to their full capacity � over and over again, as often as required. Gel cell battery systems sold for alternative energy arrays are often very expensive. You might save a lot of dollars by buying deep cycle marine batteries which are also a gel cell battery and are for this reason among the best batteries for renewable energy system. 


There are several kinds of deep cycle or deep discharge batteries. The most common kind is assumed here: flooded cell batteries. These can withstand overcharging, are low cost (compared to others) and built to have a long life. 
Other kinds also have their advantages and features, including the following: � Sealed flooded cells are maintenance free but can be damaged by overcharging. � Recombinant flooded cells are more expensive but will not spill acid. � Gelled electrolyte cells are also expensive and are more versatile in mounting. 

The above site does an in depth study of the advantages of the two types, the best place to locate the batteries, safety measures to be followed and helps in deciding the number of batteries required for quantum of usage. 

A solar battery monitor reports on the efficiency of the battery.This monitor is also helpful in telling you how many hours of charge is left in your battery. 

Once you have purchased the solar battery you need to know how to connect the battery to the solar panel. Step by step instructions to connect the solar battery to the solar panel is given at this site 

Today many outlets sell a solar generator. Its a complete solar power generating unit. It consists of a solar panel, a solar battery, an electronics that converts the solar power from the battery for household use and a AC, DC panel.

Solar batteries are deep cycle lead acid batteries.They contain dilute sulphuric acid. Many accidents have occurred from improper handling of these lead acid batteries, resulting in blindness. Protective glasses should be worn. Its important to choose the appropriate size-suited to your requirement;if the battery chosen is too small it will discharge frequently and will not serve the purpose. Awareness of the Depth of discharge is required while selecting the battery. There are several kinds of deep cycle or deep discharge batteries. The most common kind is assumed here: flooded cell batteries. These can withstand overcharging, are low cost (compared to others) and built to have a long life.

Can the startup accelerator model work for battery companies? The folks behind CalCharge, the brainchild of Lawrence Berkeley National Lab and California Clean Energy Fund (CalCEF) that hopes to attract some 30 battery companies in the San Francisco Bay Area, think so.

Through CalCharge, battery tech developers will be able to enlist the help of researchers and use equipment at Berkeley Lab and other research institutions, participate in seminars and forums, recruit engineers and other employees and network with each other to trade information. Companies can do all this on their own, of course, but they might find better results when they go through an organization that pools resources to serve a larger community.

“What I’ve been hearing for a while is that in the Silicon Valley and the software industry, there is an ecosystem to bring everybody together,” said Venkat Srinivasan, head of energy storage and distributed resources department at Berkeley Lab. “We recognize that battery companies want an ecosystem to work together.”

Battery companies generally target three markets: consumer electronics, electric cars and grid energy storage. While Srinivasan declined to divulge which startups plan to be members, there’s quite a few in the Bay Area .

Battery technology development has generated interest from prominent venture capitalists and entrepreneurs in recent years because of federal and local policies that mandate lower tailpipe and industrial emissions and a greater use of renewable energy. The federal government has awarded hundreds of millions of dollars for engineering and manufacturing lithium-ion batteries for electric cars since 2009. Grid energy storage is a promising market because the technology complements wind and solar farms by taking in electricity from these intermittent sources and releasing it to the grid as a steady source of energy. Delivering wind and solar at a steady pace helps utilities to balance their supply with demand.

Building an innovative battery company is an expensive and time-consuming undertaking. A123 Systems, for example, raised around $240 million in venture capital before its 2009 IPO, from which it raised $371 million. The company also won a 2009 federal grant of about $249 million to expand manufacturing, though it hasn’t used up all the money.

“We see that young companies are always under-resourced and need venture capital and other types of financing. They need to bridge multiple valleys of death,” said Paul Frankel, managing director of CalCEF’s innovations group.

For now, CalCharge is part of CalCEF, which is working on eventually launching it as an independent nonprofit, Frankel said. more

===================================================== Tin: The Secret To Improving Lithium-Ion Battery Life

Poor battery life and the need to recharge smart phones often remain a huge pain for consumers. Help could be on the way. Researchers at the Washington State University said Wednesday they have figured out how pack more energy into a lithium-ion battery and boost the rate of charging it.

The trick is to replace graphite with tin for the anode, which is one of the two main components in a battery cell, said Grant Norton, who headed the research and is a professor of mechanical and materials engineering at the university. Using tin can increase the energy storage capacity of a battery cell by nearly three times, he said.

Tin is better than graphite but not as good as silicon at holding onto the lithium ions. But using tin may prove a faster way to improve a battery cell’s performance. At least that was what Norton set out to prove.  Sony, for example, uses a blend of tin and other materials for some of its lithium-ion batteries. After some experimenting, Norton settled on growing tin in the form of needles (about 50 nanometers in length) and adding textures to the material to create more surface area. A larger surface area means a greater ability to hold onto more lithium ions.

Mechanics of Solar Battery ChargersAn electrical current is created by the movement of free electrons, which carry a negative charge. Normally, electrons are entangled in an orbit around the nucleus of an atom, which is made of protons and neutrons. These atomic particles are the building blocks of matter and can be found in absolutely everything. Some matter holds its electrons more tightly than others, but given enough energy, an electron can be knocked loose from its orbit. more

Benefits of Solar Battery Chargers

 They don't require external electrical sources to recharge your batteries. This means that solar battery chargers offer freedom of movement. You can find the sun pretty much anywhere on Earth during the daytime. So, if you find yourself lost in the woods with a dead cell phone, you need only the sun's rays to get it up and running again.

This lack of a typical electrical source also offers some subtler benefits. 


*aleo solar AG is to present two solar power storage systems at Intersolar (Hall A3/Stand 380): the Voltwerk VS 5 Hybrid and the S10 from E3/DC are suitable for family homes and small businesses.

Both these storage solutions can cover a large proportion of direct electricity demand (70 to 80 percent). The solar power is consumed directly as required, stored in the battery or fed into the public grid. This enables operators of photovoltaic systems to become more independent from suppliers and from rising electricity prices. “With optimum configuration, the storage systems are now a worthwhile addition to existing and new systems,” says Jörn-Bo Hein, Head of Sales Germany.

Both systems are DC coupled, fully integrated, and designed to last for up to 20 years. They are based on sophisticated lithium-ion storage systems including battery management, an inverter without transformers and a monitoring system. Monitoring is possible via an Internet portal or iPhone app. The mix of mains current, battery power and solar power is managed fully automatically and conveniently – operators do not need to modify their consumption behaviour.

The VS 5 Hybrid from the German manufacturer Voltwerk (Bosch Group) is available with a capacity of 8.8 kilowatt hours (kWh), 11 kWh or 13.2 kWh. The system ensures the greatest possible proportion of directly consumed electricity, even when consumption is high or fluctuates sharply. The electricity consumption data for a household, the status and efficiency data for the photovoltaic system and the battery are represented in real time. A further function of the VS 5 Hybrid is that it offers the best possible security of supply even in the event of a mains power failure. Voltwerk offers a five-year warranty on the whole device.

The S10 from the German manufacturer E3/DC is integrated into the home electrical network at the home junction box, so there is no need for electrical modifications to the home network or room ventilation systems. An additional USB wireless module allows straightforward integration into a home automation system. The capacity of the S10 is 5.4 kWh and this can be increased up to 10.8 kWh. E3/DC offers a six-year manufacturer's warranty on its “powerstations”. As a sales partner, aleo solar has concluded a cooperation agreement with the manufacturer E3/DC.

The VS 5 Hybrid and S10 storage systems are installed exclusively by certified installers. The first training sessions for certification will take place at the aleo academy in July. aleo solar also offers extensive support to help familiarise its authorised specialist dealers with electricity storage technology, covering everything from economic efficiency calculations to technical know-how.

    Liquid Metal Battery, a company pursuing a breakthrough battery design, has attracted Bill Gates and an oil driller as seed investors.
    The founders of Liquid Metal Battery are taking an unusual approach that they hope will slash energy storage costs and deliver batteries able to store several hours of wind and solar power. The target of the company, which was spun out of the Massachusetts Institute of Technology, is to have demonstration systems connected to the grid in three to five years, executives said. An official announcement of the series A funding is expected next month.

    The all-liquid approach reduces the degradation of electrodes that can happen in batteries and allows for the high flow of current needed for bulk storage on the grid. Most importantly, though, it means the battery can built using relatively cheap components, said materials chemistry professor and co-founder Donald Sadoway.  Like

    Solar-Powered Mouse Makes It Easier To Go Wireless

    Smartphones and tablets may be in vogue, but there are still millions of us who do most of our surfing on an old school computer. When using a desktop or laptop, navigating the Web is easier with the aid of a mouse. In the early days, mice were big and bulky, with messy wires that connected them to the computer.


    Wireless mice make it much easier to compute no matter where you are, but their fading batteries cause yet another wasteful problem. That’s why the folks at Bondidea thought up this adorable solar-powered mouse. If it catches on, it could signal a shift in the way we use and power our computer peripherals.

    Lithium Solar Batteries
    Valence U-Charge® 12 Volt & 18 Volt

    Valence Lithium Iron Magnesium Phosphate batteries provide twice the available energy and run-time at approximately half the weight of a similarly sized lead-acid battery.  For example, a 108 amp lead acid battery has 54 useful amps of energy and weights 70 pounds.  The Valence U24-12XP stores 110 amps of useful energy and weighs 35 pounds.

    Lithium iron magnesium phosphate batteries manufactured by Valence are 12 or 18 volts, have high energy storage capacity, high discharge power, are fast charging with a long cycle life, and are stable when exposed to high temperature environments.  Users have experienced excellent float and cycle life resulting in very low operating costs and
    high return on investment.

    U-Charge® XP

    The U-Charge® XP family of batteries is a perfect choice when battery energy density, space constraints, weight savings and intrinsic safety are prerequisites.  They can be used as direct replacements for similar capacity lead-acid batteries with twice the energy at half the weight.  An external battery management system is required for optimum use and is offered to make an integrated system.
