POSCO Future M invests in US-based Factorial to develop all-solid-state batteries


South Korea’s POSCO Future M has invested in battery developer Factorial, following a memorandum of understanding (MOU) signed by the two companies in November 2025 for the development of all-solid-state battery technology.

POSCO Future M is preparing for the growth of the all-solid-state battery market and will supply Factorial with a stable source of high-quality battery materials. Factorial operates a pilot plant for all-solid-state batteries in Cheonan, South Korea and is actively expanding its business.

Factorial’s all-solid-state battery platform, Solstice, delivers high levels of energy density and safety according to the company, which has established partnerships with major automakers in Korea, Europe and North America.

Factorial has been conducting sample testing of all-solid-state battery cathode materials with POSCO Future M and evaluated the Korean firm’s materials as “high-performance.”

POSCO Future M’s material design and coating technologies are optimized for all-solid-state batteries. As part of the POSCO steelmaking giant, the company is expanding its portfolio of all-solid-state battery materials, including sulfide-based solid electrolytes and silicon and lithium metal anode materials.

“Both companies have developed materials technology through a close and continuous partnership. This further developed partnership will enable us to secure competitiveness in line with the rapidly growing all-solid-state battery market,” said Hong Young-Jun, Head of Posco’s Technology Research Laboratory.
