Quino Energy, a startup commercializing a water-based organic flow battery technology licensed from Harvard University, announced that it has closed an additional $1.25M of funding to augment its recent Series Seed raise of $3.3M led by ANRI, one of the most active seed and early stage VC firms in Japan.

This Series Seed Expansion brings the total raised in the investment round to $4.55M. This funding augments $1.0M previously raised in pre-seed funding and $4.6M awarded to the company in a non-dilutive grant from the U.S. Department of Energy.

The funding group includes new investors Energy Revolution Ventures and Doral Energy Tech Ventures, while TechEnergy Ventures increased the size of their earlier investment. They join ANRI, TechEnergy Ventures, and another confidential strategic investor as major Series Seed investors.
