EGI Battery

What EGI Battery does

EGI Battery Inc. is a U.S.-based advanced battery technology and manufacturing company headquartered in Ann Arbor, Michigan. The company designs and manufactures high-performance lithium-ion and all-solid-state battery cells targeted at aerospace, uncrewed aerial systems (UAS), electric vertical take-off and landing (eVTOL) aviation, robotics (including humanoid platforms), and critical infrastructure applications where weight-constrained energy density, secure domestic supply chains, and NDAA compliance are procurement prerequisites. The product portfolio is anchored by two platforms: the Atlasion cell series, a patented silicon-anode NMC lithium-ion pouch cell line in mass production across 9.4Ah to 70Ah formats, and Kosmos, a sulfide-based proprietary all-solid-state battery (ASSB) platform that exceeded 300Wh/kg energy density in August 2023 and is offered for selective joint-development with qualified partners. The company has shipped nearly 2 million semi-solid-state cells commercially and cites validation from leading drone, eVTOL, and eAviation OEMs.

The business model is hardware sales of cells direct to enterprise OEM buyers, battery-pack integrators, and module manufacturers, supplemented by custom non-recurring engineering (NRE) joint-development programs. Products are sold off-the-shelf or through A-, B-, and C-sample joint-development engagements, with finished pack configurations routed through a network of trusted battery-pack integration partners. All revenue is generated domestically. The company is building out its Zeeb Campus manufacturing facility in Ann Arbor (Site Acceptance Testing targeted Q1 2026, Start of Production targeted Q3 2026), with phased capacity expansion from approximately 40 MWh annually in Phase 1 to approximately 80 MWh in Phase 2 and 1.3 million cells annually at full ramp. Strategic priorities include obtaining ISO 9001 and AS9100 quality certifications and reaching 95% NDAA-compliant non-China materials by cost in 2028, both of which are gating requirements for aerospace and defense procurement. The company is venture-backed following a $10 million seed round closed in March 2026 and led by TSV Capital.
