Panasonic to begin mass-production of long-life Li-ion battery system for solar-powered homes in Europe : Panasonic Corporation will begin mass- production this month of a compact, secure and long-life lithium-ion battery system the company has developed for European homes. This marks the first time for the company to produce in volume such a system designed for Europe. The lithium-ion battery system consists of the Panasonic battery module with nominal capacity of 1.35 kWh and a battery management system designed to control charge and discharge of the battery in accordance with customer needs. The battery system stores excess energy generated from the photovoltaic (PV) power system during peak hours of PV generation and discharges the energy as needed, providing a solution as a household battery storage system that helps self-consumption of solar-generated power. It will also enable households to reduce the dependence on grid power and facilitate the further spread of green ener...

RSC - J. Mater. Chem. latest articles Nicola Pinna Seung-Ho Yu, Andrea Pucci, Tobias Herntrich, Marc-Georg Willinger, Seung-Hwan Baek, Yung-Eun Sung, Nicola Pinna A one-pot template-free solvothermal synthesis of crystalline Li 4 Ti 5 O 12   nanostructures based on the “benzyl alcohol route” is introduced. The 1–2 µm sized nanostructured spherical particles are constituted of nanocrystallites in the size range of a few nm. This is the first report showing that crystalline Li 4 Ti 5 O 12   can be directly obtained by soft chemistry solution routes. The as-synthesized crystalline nanostructures show good lithium intercalation/deintercalation performances at high rates (up to 30 C) and good cycling stabilities. Annealing the nanostructures at 750 °C improves the performance, which approaches the theoretical capacity of Li 4 Ti 5 O 12   with no noticeable (less than 5%) capacity loss after 200 cycles.

New high-power Si–graphene composite electrode for Li-ion batteries : Northwestern Univ. researchers report on a new high-power Si–graphene composite anode material for Li-ion batteries in the journal Advanced Energy Materials . With current technology, the capabilities of a lithium-ion battery are limited in two ways: energy capacity is limited by the charge density, and charge rate is limited by the speed at which the lithium ions can make their way from the electrolyte into the anode. The Northwestern research team combined two techniques to combat both these problems. First, to stabilize the silicon in order to maintain maximize charge capacity, they sandwiched clusters of silicon between the graphene sheets. This allowed for a greater number of lithium ions in the electrode while utilizing the flexibility of graphene sheets to accommodate the volume changes of silicon during use. Rendering of the composite electrode with sandwiched Si clusters and in-plane defects. Clic...

Image via Wikipedia Image via Wikipedia A breakthrough in components for next-generation batteries could come from special materials that transform their structure to perform better over time. A team of researchers at the U.S. Department of Energy 's Argonne National Laboratory , led by Argonne nanoscientist Tijana Rajh and battery expert Christopher Johnson, discovered that nanotubes composed of titanium dioxide can switch their phase as a battery is cycled, gradually boosting their operational capacity. Laboratory tests showed that new batteries produced with this material could be recharged up to half of their original capacity in less than 30 seconds. By switching out conventional graphite anodes for ones composed of the titanium nanotubes, Rajh and her colleagues witnessed a surprising phenomenon. As the battery cycled through several charges and discharges, its internal structure began to orient itself in a way that dramatically improved the battery's performance. …...

Bendy batteries a step closer 25 February 2011 Scientists from Korea have found that with the use of graphene nanosheets, the fabrication of bendable power sources is possible.  Electronic devices are no longer confined to the home or office. We travel with them, carry them around and even wear them. To make equipment like roll-up displays and wearable devices achievable, the power source that supplies them must also become more flexible.  The major challenge of developing a truly bendable power source has been the shortage of material that is both highly flexible and has superior electronic conductivity. Polymers are typically used, but they can degrade at relatively low temperatures, which makes them less than ideal.  Kisuk Kang from the Korea Advanced Institute of Science and Technology in Daejon, and colleagues, have developed a graphene based hybrid electrode producing a flexible lithium rechargeable battery. The cathode material, in this case V2O5, is grown on graphene paper usi...

Ioxus Inc. is an up and comer in the energy storage industry that has plans this Monday to announce a new hybrid storage device that it hopes will radically alter batteries used in the auto, medical, and consumer electronics industries. The teased product is said to be roughly the size of a typical C-cell battery and combines the fast charge / discharge benefits of ultracapacitors with the impressive energy-to-weight ratio of a lithium-ion electrode. As a result, Ioxus says the hybrid devices can store more than double the energy of traditional ultracapacitors and charge in a matter of seconds. The catch is that the hybrids have shorter life spans of 20,000 cycles compared to millions of cycles for typical ultracapacitors. We're also taking this with a grain of skepticism until these claims are proven in the field. Some brief digging though did unearth an article written by MIT researchers and published in Scientific American last year that discusses the possible benefits of s...

Article in Journal of Materials Chemistry titled as Flexible and planar graphene conductive additives for lithium-ion batteries and describes yet another graphene application in Li ion batteries. Authors claimed that Graphene is introduced into a lithium-ion battery (LIB) as a type of novel but powerful planar conductive additive and the flexible graphene-based conducting network is characterized by a novel “plane-to-point” conducting mode with exceptional electron transport properties and unique geometrical nature (a soft and ultrathin planar structure). With a much lower fraction of graphene additives than those of commercial carbon based additives, the graphene-introduced LiFePO4 cathode shows better charge/discharge performance than commercial cases. Graphene also shows a better performance compared to carbon nanotubes, another type of novel conductive additive with similar fractions. These results present us an indication that graphene will possibly find early application...

New hybrid materials of Mn3O4 nanoparticles on reduced graphene oxide (RGO) sheets for lithium ion battery applications have been developed in Department of Chemistry and Laboratory for Advanced Materials and Department of Materials Science and Engineering, Stanford University. They selectively grow of Mn3O4 nanoparticles on RGO sheets, and in contrast to free particle growth in solution it allowed for the electrically insulating Mn3O4 nanoparticles to be wired up to a current collector through the underlying conducting graphene network. The Mn3O4 nanoparticles formed on RGO show a high specific capacity up to 900 mAh/g, near their theoretical capacity, with good rate capability and cycling stability, owing to the intimate interactions between the graphene substrates and the Mn3O4 nanoparticles grown atop. The Mn3O4/RGO hybrid could be a promising candidate material for a high-capacity, low-cost, and environmentally friendly anode for lithium ion batteries. Such approach may offer a ...

The nanoporous material has by desi...

London, January 3 (ANI): It seems that the dream of environmentally friendly aviation is very close to reality, with a French test pilot successfully flying an aircraft propelled by an electric motor. The Electra is a single-seater plane, made up of wood and fabric. Having flown for 48 minutes for 50km around the southern Alps, it has proved that applying battery power to a fixed-wing standard aircraft is possible. The APAME group, founded to develop green aviation, announced this groundbreaking flight. This will be a real aeroplane that will have an airworthiness certificate. It is a machine built for anyone with a pilots licence, Times Online quoted Anne Lavrand, president of APAME, as saying. She also revealed that her team, financed by French aerospace companies and other donors, started working on this project quietly 18 months ago. When we began, no one believed we could do it, she said. Lavrand further revealed that her group used a Souricette kit aircraft, and adapted to it a 2...

Yet another "hybrid" type or some kind of battery/capacitor energy storage concept... Battery-like device could power electric cars - CNN.com : "AUSTIN, Texas (AP) -- Millions of inventions pass quietly through the U.S. patent office each year. Patent No. 7,033,406 did, too, until energy insiders spotted six words in the filing that sounded like a death knell for the internal combustion engine. An Austin-based startup called EEStor promised 'technologies for replacement of electrochemical batteries,' meaning a motorist could plug in a car for five minutes and drive 500 miles roundtrip between Dallas and Houston without gasoline. By contrast, some plug-in hybrids on the horizon would require motorists to charge their cars in a wall outlet overnight and promise only 50 miles of gasoline-free commute. And the popular hybrids on the road today still depend heavily on fossil fuels. 'It's a paradigm shift,' said Ian Clifford, chief executive of Toronto-base...

Rechargeable lithium ion batteries are found in laptop computers, mobile phones an...

Here are all news about latest recall

Tokyo -- Tales of burning notebook PCs that hit the news last summer raised serious concerns among consumers about the safety of lithium-ion batteries. Responding to those fears, Japan's battery and PC industries have jointly hammered out guidelines for the safe use of Li-ion batteries. The industries' task force has also presented its proposal to the International Electrotechnical Commission (IEC). "We have worked hard since last October for lithium-ion battery safety. The resulting guidelines are designed to eliminate serious problems, such as catching fire," said Masami Yamamoto, corporate vice president of Fujitsu Ltd., who chaired the safety committee formed last fall by the Japan Electronics & Information Technology Industries Association (JEITA) and the Battery Association of Japan. As the next step, the team intends to expand the guidelines beyond notebooks to other applications, such as cell phones. The guidelines are not intended to clarify the cause of ...

The KillaCycle, an all-electric motorcycle, is now the fastest electric vehicle of all time. At a drag race in Chandler, Ariz., the bike completed a quarter mile in 8.168 seconds, breaking the six-year-old record of 8.801 held by Dennis Berube with an electric car for more than six years. The bike cranked it up to 155.87 miles an hour. Even more impressive, it hit this level of performance twice, on April 3 and April 4. The bike is powered by 990 lithium ion cells from A123 Systems, a Massachusetts start-up that is also making batteries for General Motors. (A123 also makes the batteries for the Atlas Powered Rope Ascender, a device invented at MIT that can scoot a person 300 feet up a rope in about a half a minute.) An earlier version of the bike only had 880 battery cells. Full story

Not much information right now. This certainly doesn't mark the first case in which the US Army has fiddled with hybrid vehicles, but the Maneuver Sustainment Vehicle (MSV) that the military is currently testing out most definitely ups the ante in other areas. The diesel-electric hybrid truck touts an insanely rugged frame designed to "sustain the concussion of a roadside bomb," and after it brushes off that weak attempt to render it immobile, the remote weapons system should inflict a fair amount of vengeance on the enemy. Moreover, the highly-spec'd machines also feature night vision capabilities, touchscreen controls, swarms of video cameras, and ballistic-grade glass to boot. Unfortunately, the limited fleet of MSVs are currently being recognized as "concept vehicles" to be used for demonstration purposes alone, but we're sure there's a number of defense contractors that could piece together a slightly less vicious version for your own garage if ...
