Battery maker SK On is partnering with U.S. battery startup Factorial Energy to assess whether solid-state batteries can be mass-produced using SK On’s existing lithium-ion production lines. Under an MOU, the companies will review how SK On plants and equipment can support Factorial’s FEST solid-state technology. Factorial is conducting vehicle validation in North America with Stellantis, which has disclosed performance data for a 77Ah FEST cell. Factorial also works with other automakers and has signed similar non-binding agreements with materials companies.
