Cosmos Lab Secures KRW 22 Billion Series A Funding... Accelerates Mass Production of 'Nonflammable' Non-Lithium Batteries

Cosmos Lab, a next-generation non-lithium battery cell company, has secured KRW 22 billion in Series A funding. Both domestic and international institutional investors, as well as strategic investors (SI), participated in this round. The company has completed investment agreements totaling KRW 22 billion and plans to complete the final payment by the end of this month.

On August 12, a Cosmos Lab official stated, "The investments will be focused on advancing the technology of aqueous zinc-halogen batteries and on building mass production and global commercialization infrastructure to respond to the expanding AI data center and next-generation energy storage system (ESS) markets."

Development of Electrolyte-Based Nonflammable Batteries

Cosmos Lab is developing next-generation batteries that use water-based, nonflammable electrolytes and zinc and halogen-based materials. Unlike conventional zinc-bromine flow batteries and vanadium flow batteries, its integrated cell structure does not require external electrolyte tanks or circulation pumps, incorporating halogen reaction technology instead. This approach maximizes both energy density and space efficiency while maintaining the high safety standards of aqueous batteries.

Cosmos Lab is engaged in the integrated development of anode and cathode materials, separators, electrolytes, charge-discharge operation technologies, cell structures, and manufacturing processes, which cover the entire lifecycle from materials to cell operation. Based on this, the company aims to quickly transition aqueous zinc-halogen batteries from the research and development stage to large-capacity commercial cells and mass-producible products.

Joint Development with SoftBank... Targeting Mass Production by 2027

Recently, as the focus of the global battery market has shifted from electric vehicles to AI data centers and grid ESS, capital is pouring into non-lithium Long Duration Energy Storage (LDES) technologies to complement lithium-ion batteries. The implementation of the U.S. Inflation Reduction Act (IRA) and the EU’s Critical Raw Materials Act (CRMA) have made supply chain stability and eco-friendly manufacturing competitiveness key factors, which is further driving momentum for non-lithium batteries.

Cosmos Lab plans to use the investment funds to strengthen domestic R&D capabilities and secure reproducibility and productivity for large-capacity cell manufacturing processes. The company will sequentially pursue testing and certifications required for ESS and AI data center environments, while simultaneously verifying module, rack, and system applications, with the goal of establishing a foundation for products that global customers can actually adopt and for mass production.

Collaboration with global companies on commercialization is also accelerating. Cosmos Lab is conducting joint development with SoftBank for the mass production of aqueous zinc-halogen battery cells. It is developing next-generation ESS technology for AI data centers, aiming to start mass production next year. The company is also discussing demonstration collaborations with AI and data center companies in North America, Asia, and Europe. In the future, it plans to expand its applications to renewable energy-linked ESS, industrial power storage devices, and distributed grid markets.

A Cosmos Lab official commented, "This investment marks a crucial turning point in transforming our R&D achievements into globally mass-produced products," and added, "We aim to grow into Korea’s leading non-lithium battery company in the AI data center and grid ESS markets, and ultimately establish a new global standard for electric infrastructure."
