Defective cells can shorten battery life, decrease range, and lead to safety issues. A leaky cell housing, one common failure mode for Li-ion batteries, can allow ambient humidity to come in contact with the electrolyte, triggering an exothermic (heat-releasing) chemical reaction. Currently, the common practice in the battery manufacturing industry is to test cell packaging… Read more »

Battery test simulation tech helps OEM overcome fast-charge challenge
D2H Advanced Technologies has delivered a project that solves a known charging issue with a production EV. The company deployed its battery simulation and correlation capability to enhance battery thermal management in a fast-charge scenario, accelerating the development process to reduce excess noise from high pumping power and help the dissipation of heat. The project… Read more »
Hong Kong researchers propose novel cathode design for Li-S batteries
A team led by Professor Zhao Tianshou of the Hong Kong University of Science and Technology has proposed a novel cathode design concept for lithium-sulfur (Li-S) batteries. Li-S batteries are regarded as attractive alternatives to Li-ion batteries. They are known for their high energy density, while their major component, sulfur, is abundant, light, cheap and… Read more »
New class of cobalt-free cathodes could enhance energy density of Li-ion batteries
Oak Ridge National Laboratory (ORNL) researchers have developed a new family of cathodes with the potential to replace the costly cobalt-based cathodes typically found in today’s lithium-ion batteries. The new class, called NFA (nickel, iron, aluminum), is a derivative of lithium nickelate that’s used as a cathode material. These novel cathodes are designed to be… Read more »
GM announces new business venture to produce electric delivery vans
Over the past few months, GM has gotten a lot more serious about electrification, unveiling a new EV platform, plans for more investment and more electrified models, and most recently, a new EV-centric marketing campaign. However, some have been pointing out the gap between the automaker’s high-wattage future plans and its flickering present (only one… Read more »
FREYR and 24M to collaborate on battery cell production
FREYR and 24M have signed an agreement to use 24M’s SemiSolid lithium-ion battery platform technology in FREYR’s planned facilities in Norway. FREYR is targeting a production capacity of over 40 GWh of scalable, modular battery cells via partnership-based strategies in both grid and electric mobility markets. “24M has fundamentally redesigned the traditional LIB cell technology… Read more »
Compact EV-specific transmission supports niche OEMs as they shift to electric
Following the recent release of its HPD E crate motors and associated kit to electrify the classic Mini, Swindon Powertrain is now extending its electrification range with a new standalone E-Transmission for EVs. Swindon says the single-speed gearbox is an affordable plug-and-play solution to purchasing a transmission to work with existing electric motors. With two… Read more »
Discoveries highlight new possibilities for magnesium batteries
Magnesium batteries have long been considered a potentially safer and less expensive alternative to lithium-ion batteries, but previous versions have been severely limited in the amount of power they delivered. Researchers from the University of Houston and the Toyota Research Institute of North America (TRINA) reported in Nature Energy that they have developed a new… Read more »
European truck-makers pledge to phase out internal combustion vehicles by 2040
Several of Europe’s largest truck manufacturers have promised to stop selling ICE vehicles by 2040. The chief executives of Daimler, Scania, MAN, Volvo, DAF, IVECO and Ford have signed a pledge to phase out combustion engines and focus on hydrogen, battery technology and “clean fuels.” The industry will invest some 50 to 100 billion euros… Read more »
IC Solutions For Safe And Reliable Propulsion Inverters
In this session, we will review the trends affecting the design of traction inverters, the challenges imposed by the migration towards higher bus voltages, and the need to meet ISO26262 “functional safety”. The changes required to support high-voltage SiC MOSFET switching modules will also be examined. New IC solutions that enable effective and efficient isolated… Read more »
