Nickel-Zinc Battery Company Raises $30 Million - CleanTechnica

ZincFive, a company specializing in nickel-zinc (NiZn) battery solutions for immediate power applications, has successfully raised $30 million in an oversubscribed Series F funding round, bringing its total funding to $254 million since its founding in 2016. The new capital will support rapid scaling of ZincFive’s commercial and manufacturing operations to meet growing demand, particularly from AI data centers requiring reliable power backup. ZincFive claims to be a world leader in NiZn battery technology, having deployed or contracted 2 gigawatts (GW) of battery backup capacity, notable for this less common battery chemistry. The company highlights its nickel-zinc batteries as safer and more sustainable alternatives to lead-acid and lithium-ion options, offering superior power density, inherent safety (zero thermal-runaway risk), and a 96% recyclable design. ZincFive’s technology is engineered for the dynamic power needs of AI data centers, which represent a significant and rapidly expanding market due to the massive power demands of AI
