Factorial Energy Inc. has signed a non-binding Memorandum of Understanding with SK On Co., Ltd. to evaluate the manufacturing potential of solid-state battery cells. The agreement brings together Factorial’s FEST® solid-state cell technology and scale-up expertise with SK On’s global lithium-ion production infrastructure. SK On operates more than 200 GWh of annual capacity worldwide—approximately 100 GWh in the U.S.—including a 22 GWh facility in Commerce, Georgia, and additional operations in Tennessee. The company supplies electric vehicle batteries to several major automakers.
Under the MOU, the two companies will collaborate on technical feasibility studies and manufacturing assessments to determine how SK On’s existing footprint could accommodate Factorial’s next-generation solid-state platforms. These studies will draw on SK On’s pilot capabilities, battery engineering resources, quality management processes, and global production network. Factorial’s capital-light strategy focuses on leveraging established manufacturing lines to accelerate industrialization, reducing the time and investment typically required to bring new cell chemistries to market.
Factorial’s solid-state cells are engineered for high energy density, safety, and long cycle life. They aim to serve a range of applications—including electric mobility, aerospace systems, and hyperscale data centers—by enabling smaller, lighter battery packs that deliver system-level efficiency. Siyu Huang, CEO of Factorial Energy, noted that “a battery breakthrough only matters if it can be manufactured at scale,” and highlighted the importance of SK On’s advanced facilities in integrating and optimizing solid-state cells for mass production.
Ki-soo Park, Head of the Institute of Future Technology at SK On, said the collaboration offers a valuable opportunity to assess manufacturing readiness for next-generation battery technologies and explore further development partnerships. The MOU outlines planning activities and technical exchanges, with definitive binding agreements to follow once both parties complete due diligence and negotiate detailed terms and timelines.
