Company Overview

Anthro Energy, founded in 2021 and based in Alameda, California, advances lithium-ion battery performance and safety through its proprietary Anthro Proteus™ electrolyte technology. The company aims to improve battery stability and safety while boosting energy density and supporting advanced chemistries, targeting sectors such as consumer electronics, EVs, and defense. It is also investing in domestic supply chain strengthening with a large-scale electrolyte production facility in Kentucky.

Battery Technology

Anthro Energy’s core technology is the Anthro Proteus™ electrolyte platform, a unique injectable phase-change electrolyte that transitions from a liquid to a solid, non-flammable polymer within the battery cell. This solid state electrolyte prevents leakage, enhances structural integrity, suppresses flammability, and significantly improves mechanical toughness by 10 times. Proteus supports various cell sizes, shapes, and chemistries, including silicon anodes, and integrates into existing manufacturing lines without requiring costly equipment changes.

Products

Anthro Energy produces structural battery cells that can be formed into unconventional geometries like drone wings or vehicle chassis components, along with electrolyte solutions for lithium-ion, solid-state, and semi-solid battery systems. These products enhance energy density, safety, and durability across markets including consumer electronics, automotive, defense, and micromobility.

Recent Projects

Significant projects include the January 2025 commercialization launch of Anthro Proteus™, federal tax credits in February 2025 supporting their Kentucky production facility, and plans for a pilot manufacturing facility in Alameda County by mid-2025. Past achievements include a successful Series A funding round in 2024, $25 million funding from the U.S. Department of Energy in 2023, $18.4 million in federal tax incentives, UN 38.3 certification for their batteries, and initial deployments in extreme environments validating their technology’s reliability.

Investors

Anthro Energy has attracted funding from venture capital firms including Collab Fund, Union Square Ventures, Emerson Collective, National Security Innovation Capital, and Energy Revolution Ventures. The company has raised over $27M in equity financing, supplemented by federal grants and tax credits. Strategic partnerships with IQT, the U.S. Department of Energy, and the Department of Defense highlight the strategic importance of its technology.
