Anthro Energy

Anthro Energy is a battery technology company developing advanced electrolyte solutions and flexible battery cells that improve lithium-ion battery safety, energy density, and design flexibility. The company’s flagship Anthro Proteus platform is an electrolyte technology providing an unprecedented combination of performance, safety, and mechanical integrity. Proteus delivers 10x improved toughness with resistance to swell, short circuit, impact, and fire; up to 35% improved energy density by unlocking next-gen chemistries like silicon anodes; highly tunable compatibility with all cell shapes, sizes, and chemistries; and 100% drop-in compatibility with existing manufacturing infrastructure including today’s gigafactories. Anthro offers both battery cells and electrolyte solutions, serving consumer electronics (smaller, lighter, longer-lasting devices), micromobility (durable, long-range batteries), defense (rugged, safe, lightweight US-manufactured batteries), and automotive (giga-scale manufacturing for EVs). The company was awarded $18.4 million in federal tax credits to build the first U.S.-owned advanced electrolyte facility in Alameda, California. Founded in 2020 and headquartered in Palo Alto, California, Anthro has raised approximately $27.2 million in Series A funding. Investors include Collab Fund, Union Square Ventures, Emerson Collective, Voyager, In-Q-Tel, Energy Revolution Ventures, and Ultratech Capital Partners.
