Anthro Energy announced two major milestones: the closing of an over-subscribed $20M Series A financing round and completion of UN 38.3 battery certification, a key global safety standard for lithium battery transport. Collaborative Fund led the financing, with significant participation from existing investors including Union Square Ventures, Emerson Collective, and Voyager Ventures. Energy Revolution Ventures, Ultratech Capital Partners, Nor’easter Ventures, and Overlap Holdings also participated in the round. The funds will be used to build a Bay Area-based pilot production facility to commercialize and scale Anthro’s advanced battery technologies.

Anthro’s key innovation is its advanced non-volatile and mechanically tunable polymer electrolyte. The company’s proprietary polymer replaces the highly flammable liquid electrolyte in conventional lithium-ion batteries. “Our polymer electrolyte provides an unprecedented combination of performance, safety, and mechanical integrity,” said Anthro CTO Joe Papp, Ph.D. “By replacing conventional liquid electrolytes with our polymer, we can enable new battery form factors and battery chemistries that can facilitate broader electrification efforts across our economy.”
