Charged EVs | GM and Microvast to develop new battery separator tech, build US plant

GM and battery producer Microvast are collaborating to develop specialised EV battery separator know-how, and to construct a brand new separator plant within the US, supported by a $200-million grant from the DOE’s Battery Supplies Processing and Battery Manufacturing initiative.

Separators are battery parts that separate the anode from the cathode, whereas permitting for ion switch. GM will contribute its separator and coating know-how to the collaboration. This know-how is designed to boost the thermal stability of batteries and to work with practically all sorts of lithium-ion cells, together with graphite, silicon, and lithium-metal anodes and nickel-rich, cobalt-free, lithium iron phosphate and high-voltage cathodes.

“This collaboration with Microvast helps our efforts to develop a North American-focused EV provide chain and assist put everybody in an EV,” stated Kent Helfrich, GM’s Chief Expertise Officer. “It would additionally present us with separator know-how that can be utilized in future Ultium batteries.”
