“We’re also proud to contribute to the [US] onshoring of battery manufacturing for EVs and advancement of battery innovation for a differentiated supply chain.”

Earlier this year, Factorial received United Nations 38.3 safety certification enambling it to ship its cells to automakers overseas. The certification is a requirement for the safe transport of lithium-ion and lithium metal batteries.

Executive chairman Joe Taylor said: “Automaker demand for American made batteries is high [so they can] produce electric or hybrid vehicles that qualify for incentives.

“Our facility will manufacture automotive size solid state batteries at preproduction speed and volume, illuminating a clear path to mass production and reaching economies of scale.”
