ZincFive, a nickel-zinc battery-based solutions company, has raised an oversubscribed $30 million Series F funding round, bringing the company’s total investment to $254 million to date.
With this funding, the company plans to expand its commercial footprint and manufacturing capacity to meet the accelerating demand for AI data center power solutions.
“The AI infrastructure buildout represents one of the largest technology investment cycles in history, and power systems are emerging as a critical bottleneck,” said Hannah-Mei Andrews, Investment Director at Climate Investment (CI).
To meet this emerging demand for AI, the company recently announced the launch of its BC 2 AI, a nickel-zinc UPS battery cabinet engineered to meet the power needs of AI data centers, offering AI load support, a claimed zero thermal runaway risk, and a 96 percent recyclable design.
ZincFive has stated that it has deployed or contracted nearly 2 GW of nickel-zinc battery backup cabinets and is scaling production to execute on its growing commercial pipeline.
Since 2016, the company has been backed by a consortium of climate and industrial investors, including Helios Climate Ventures, Climate Investment (CI), Japan Energy Fund, General Ventures, and Clear Creek Investments, among others.
In 2022, the company raised $54 million in Series D funding. Helios Climate Ventures led the funding round with participation from Senator Investment Group, Standard Investments, OGCI Climate Investments and the Japan Energy Fund, among others.
According to Mercom’s 9M and Q3 2025 Funding and M&A for Energy Storage report, VC funding in the sector totaled $2.8 billion across 56 deals, a 4% YoY increase from $2.7 billion across 61 deals in 9M 2024.
Last year, Enzinc, an advanced zinc battery developer, raised $8 million in a Series A funding round led by TO VC, with participation from American Century Investments (ACI), which led Enzinc’s seed round.
