- Factorial Energy has been working on solid- and semi-solid-state batteries for years.
- The startup will now evaluate whether it can use SK On's existing battery plants to mass produce its solid-state cells.
- Its semi-solid-state batteries are already testing in prototype EVs out in the real world.
Massachusetts-based battery startup Factorial Energy has signed a memorandum of understanding with South Korean battery giant SK On to explore how solid-state batteries can be mass-produced using existing lithium-ion manufacturing lines.
