Factorial and SK On Sign MoU to Explore Solid-State Battery Manufacturing
BOSTON, July 29, 2026 (GLOBE NEWSWIRE) — Factorial Energy Inc.(Nasdaq: FAC) (“Factorial” or the “Company”), a global leader in next-generation solid-state battery technology, today announced it has signed a Memorandum of Understanding (MOU) with SK On Co., Ltd. (“SK On”), a leading global battery manufacturer. This 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 world-class manufacturing footprint and existing lithium-ion battery manufacturing infrastructure could support future development of solid-state battery technologies.
SK On is recognized as a leading global manufacturer of electric vehicle batteries serving automotive OEMs including Hyundai Motor Group, Ford, Volkswagen, and Ferrari. The company has more than 200 GWh of annual production capacity worldwide, including approximately 100 GWh in the United States. Its U.S. manufacturing footprint includes 22 GWh of capacity in Commerce, Georgia, as well as operations in Tennessee.
Under the MOU, Factorial and SK On will jointly evaluate the technical feasibility and manufacturing considerations for Factorial’s FEST® solid-state battery technologies, drawing on SK On’s battery technology and manufacturing expertise, as well as its global manufacturing capabilities.
The collaboration highlights Factorial’s capital-light approach to industrialization, which is centered on developing batteries that can leverage established manufacturing infrastructure to accelerate the path to industrialization.
Siyu Huang, CEO of Factorial, said:
A battery breakthrough only matters if it can be manufactured at scale,
“That is what makes this partnership with SK On so significant. Their manufacturing footprint spans some of the world’s most advanced battery facilities, and their expertise will be critical in shaping how solid-state battery technology integrates into global production ecosystems.”
Factorial’s solid‑state platforms are engineered to serve as the core energy foundation for next‑generation mobility, aerospace systems, and hyperscale data centers. Factorial’s high energy density batteries enable smaller, lighter batteries and deliver system level efficiency required for increasingly demanding missions across land, air, and orbit.
Ki-soo Park, Head of the Institute of Future Technology at SK On, said:
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,
“SK On will continue to explore collaboration opportunities in next-generation battery technologies.”
Through this collaboration, Factorial and SK On will explore opportunities to support the future development of solid-state battery technologies for mobility and high-performance markets, advancing the next generation of energy storage. This marks Factorial’s manufacturing-focused partnership with a global battery producer, reflecting the company’s strategy of scaling through established manufacturing ecosystems.
The MOU is non-binding, except for certain customary binding provisions. The terms of the collaboration are expected to be set forth in definitive binding agreements.
