One of the drawbacks of lithium-ion batteries is that they tend to suffer power loss in cold weather. At temperatures below freezing, charging is slower, regenerative braking is restricted and vehicle range can be reduced. Now researchers from Penn State and spin-off company EC Power have developed a battery that […]

The idea of hitting 100% renewable energy (yes, energy, not just electricity) scares a lot of people. That is, a lot of people don’t think their cities or countries can achieve 100% renewable energy. However, a leading energy researcher at Stanford has led teams of researchers in order to practically […]

As the search for a better battery grinds on, a lot of the attention is focused on potential cathode materials. Nickel is one possibility that shows a lot of promise – its drawback is that it is unstable and tends to have destructive reactions with the electrolyte. Now a team […]

Stanford researchers have invented a new technology that could eliminate thermal runaway in high-energy-density batteries. Thermal runaway refers to a chain reaction in which an increase in temperature causes further increases in temperature and uncontrollable release of energy. In “Fast and reversible thermoresponsive polymer switching materials for safer batteries,” published in Nature […]

Saft has signed an agreement with SNCF, the national railway operator in France, to provide nickel-based batteries for over 200 trains, which employ the Alstom Coradia Duplex electric multiple unit (EMU) platform. These trains can achieve 160 km/h and are used in regional routes in France. The Saft/SNCF contract has been valued at about […]

Texas Instruments (NASDAQ: TXN) has introduced what it calls the industry’s first integrated battery monitor and protector. The enticingly-named bq76PL455A-Q1 provides cell-voltage monitoring for large batteries with up to 256 cells in a series. The bq76PL455A-Q1 is designed to reveal a pack’s state of charge and state of health by […]

Litarion, a subsidiary of Electrovaya Inc, has introduced a new, thinner flexible ceramic separator for utility-scale and EV applications. Among all cell components, the separator, is responsible of preventing the contact between the electrodes while permitting a free transport of ions in the cell. Its properties are also closely related […]

Navitas Systems, a provider of energy storage products and power electronics, has won a $7.2 million contract to develop next-generation lithium-ion batteries for military vehicles. As new power-hungry electronics proliferate, the US Army’s Tank Automotive Research, Development, and Engineering Center (TARDEC) has been working with Navitas to develop prototype 24 […]

A new prototype “intelligent battery cell” has been developed by researchers at the Fraunhofer Institute for Manufacturing Engineering and Automation IPA in Stuttgart that could lead to electric vehicle battery pack costs being slashed notably. In addition to potential cost cuts, the new prototype could also lead to battery packs […]

Nissan and Eaton have announced a partnership that will use their respective expertise in lithium-ion batteries and power electronics to create commercially viable energy storage and control centers that offer a productive second life for Nissan’s EV batteries after their days on the road. The two companies will deploy a […]

A research team sponsored by Hitachi and Tohoku University’s Advanced Institute for Material Research (AIMR) has demonstrated technology that reduces the internal resistance of all-solid-state Li-ion batteries through the use of LiBH4-based complex hydrides as solid electrolytes. A conventional Li-ion battery uses a volatile organic electrolyte solution with a maximum […]

Scientists from Nanyang Technological University have developed a smart chip that they say provides a more precise picture of battery health than current warning systems, many of which only alert users when the battery is already overheating. Developed by Professor Rachid Yazami of the Energy Research Institute @ NTU, the […]
