Founded in 2020, Cellforce Group GmbH is a wholly owned subsidiary of Porsche Erste Beteiligungsgesellschaft mbH based in Tübingen that develops and manufactures high‑performance battery cells for vehicle and mobility applications. The company deliberately targets the high‑performance and premium segment and focuses R&D on cell chemistry with a high‑silicon anode to increase energy density, performance and fast‑charging capability. Its core product is a prismatic cell (CF3) for the SSP61 platform; activities for a pouch cell were discontinued and findings were transferred into the CF3 project. To scale production, a factory in Kirchentellinsfurt is planned with an estimated investment of about €204 million and planned capacity of 0.8 GWh; full production completion is planned for 2025 and series production (SOP) is targeted for 2029.
