Cosmoslab raises $15.6M Series A for non-lithium battery push
What's the deal? Cosmoslab, a South Korean maker of non-lithium battery cells, has raised a 22 billion KRW ($15.6 million) Series A led by Smilegate InvestmentDealroom has a profile for this one.

What's the endgame? The company develops aqueous zinc-halogen batteries that use a water-based, non-flammable electrolyte. Unlike zinc-bromine or vanadium flow batteries, its integrated cell design skips external electrolyte tanks and circulation pumps, aiming to combine the safety of aqueous cells with higher energy density.
Cosmoslab plans to use the funds to advance the technology and build mass-production and global commercialisation capacity for AI data centre and energy storage system (ESS) markets. It will strengthen domestic research, pursue certification, and validate products up to module, rack, and system level.
Why now? The company is co-developing zinc-halogen cells with SoftBankDealroom has a profile for this one. Try Dealroom →, targeting mass production in 2027 for next-generation AI data centre ESS. It is also in talks with AI and data centre firms in North America, Asia, and Europe on demonstration projects.
The signal: As battery demand shifts from electric vehicles toward AI data centres and grid ESS, government and private capital is flowing into non-lithium long-duration storage. The US Inflation Reduction Act and the EU Critical Raw Materials Act have pushed supply-chain stability and clean manufacturing to the fore, adding momentum to alternatives to lithium-ion. "This investment is an important turning point in converting our R&D results into global mass-production products," a Cosmoslab representative said.
