Innox Lithium and JS Chem Partner on All-Solid-State Battery Materials

South Korea-based Innox Lithium Co Ltd has entered into a Memorandum of Understanding (MOU) with JS Chem Corporation to jointly advance the all-solid-state battery materials business. Through this collaboration, the companies intend to strengthen the supply chain for next-generation battery materials by combining their respective expertise in high-purity lithium hydroxide and lithium sulfide production. The partnership is designed to support future commercialization efforts while creating a reliable manufacturing ecosystem for advanced battery applications.

Partnership Focuses on Battery Material Supply Chain

As outlined in the agreement, Innox Lithium will provide high-purity lithium hydroxide to JS Chem, which will use the material to establish a production supply chain for lithium sulfide. This collaboration brings together complementary capabilities that are expected to accelerate the development of critical materials required for all-solid-state batteries. By integrating raw material supply with specialized processing technology, both companies aim to improve production readiness and strengthen long-term manufacturing capabilities.

Production Capabilities Support Commercialization Plans

Innox Lithium completed its high-purity lithium hydroxide manufacturing plant in Ochang, North Chungcheong Province, in November 2025 and has already established a mass production system. Meanwhile, JS Chem has developed proprietary lithium sulfide production technology and has supplied prototype materials to companies in United States, Japan, and South Korea for evaluation testing. Building on these achievements, the companies plan to establish a stable mass production system as quickly as possible with the objective of commercializing the technology in 2027.
