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 […]

Samsung SDI will supply cylindrical 18650 format Li-ion battery cells for the new electric SUV iEV6S from , one of China’s top 10 domestic automakers. The battery pack for the iEV6S will use around 3,000 of Samsung’s 18650 cells. The two companies have signed an MOU for the supply of […]

Silicon’s high theoretical charge capacity has inspired a tremendous amount of research into the possibility of using it to replace at least part of the graphite in lithium-ion battery anodes. However, Si presents major technical challenges. It can undergo a volume change of up to 300% during charging and discharging, […]

The Tesla Model X is the first fully electric SUV in the world. It was announced with much fanfare — Bioweapon Defense Mode! Falcon-wing doors! Clown-car volumes of people and luggage coming out! — by Musk with a handful of lucky and rich people getting early editions and paying a […]

Known for artsy watches, it may seem strange that Swatch is considering a move into the electric vehicle battery game, until you start to dig into the details. Swatch has been making batteries for watches for years, so the connection to the technology makes sense, but it’s the specific battery […]

High-performance magnets, which are critical for EV motors, typically depend on rare earth elements such as samarium, neodymium and dysprosium. These exotic materials are not only costly, but also present environmental and political challenges. Researchers from Tohoku University in Japan recently succeeded in producing a completely rare-earth-free high-quality magnet made […]
