GM And Microvast Get $200 Million Government Grant To Make EV Batteries Safer

The new separator technology will enhance the thermal stability of EV batteries, which has been a contentious issue following several high-profile EV fires. GM has been at the receiving end of a fire scandal, even though the Chevrolet Bolt batteries were supplied by a third party.

The separator will be designed to work with all sorts of lithium-ion cells, including graphite, silicon, and lithium-metal anodes and nickel-rich, cobalt-free, lithium-iron phosphate-type, and high-voltage cathodes.

“This collaboration with Microvast supports our ongoing efforts to develop a North American-focused EV supply chain and help put everyone in an EV,” said Kent Helfrich, GM chief technology officer and vice president of research and development. “It will also provide us with pioneering separator technology that can be used in future Ultium batteries and, most importantly, supports our continuing commitment to safety.”
