US-based Factorial Energy Inc., a tech firm specialising in next-generation solid-state batteries (SSB), has signed a Memorandum of Understanding (MoU) with SK On, a Korea-based battery manufacturer, aimed at exploiting future manufacturing synergies. The partnership brings together Factorial's advanced cell technology and scale-up expertise with SK On's extensive global manufacturing network and pilot capabilities. A key objective of this collaboration is to assess whether and how SK On's manufacturing footprint and existing lithium-ion battery manufacturing infrastructure could support future development of SSB technologies. Under the MoU, Factorial and SK On will jointly evaluate the technical feasibility and manufacturing considerations for Factorial's FEST SSB technologies. "This collaboration provides an opportunity to evaluate the technical feasibility and manufacturing readiness of solid-state battery technologies, drawing on SK On's battery technology and manufacturing expertise," said Ki-soo Park, Head of the Institute of Future Technology at SK On.
