EGI Battery, a U.S.-based advanced battery manufacturing startup focused on high-performance lithium-ion cells for aerospace, robotics, and unmanned systems, has raised $10 million in a seed funding round as it accelerates its domestic production strategy and expands its Michigan-based manufacturing footprint.

The company develops silicon-enhanced lithium-ion pouch cells designed for mission-critical applications, including drones, electric aviation, and defense-related robotics systems. Its technology emphasizes high energy density, performance reliability, and secure domestic supply chains aligned with NDAA (National Defense Authorization Act) requirements. EGI Battery positions itself as part of a new generation of U.S. battery manufacturers seeking to reduce reliance on overseas supply chains while scaling advanced energy storage technologies domestically.

The seed round was led by TSV Capital, a venture firm focused on early-stage investments in deep technology and industrial innovation. In addition to the lead investor, the round included participation from several U.S.-based family offices, which are not publicly disclosed and therefore cannot be linked.

The new capital will be used to expand EGI Battery’s manufacturing operations at its Zeeb Campus in Ann Arbor, Michigan, as well as accelerate engineering development and commercial deployment of its battery products. The company is building a phased production system that includes electrolyte filling, cell formation, and full-scale assembly capabilities, with long-term plans to vertically integrate electrode manufacturing and increase output capacity significantly.

EGI Battery’s Michigan facility is designed to support scalable production of lithium-ion pouch cells for both commercial and defense applications. The company’s initial manufacturing phase targets tens of megawatt-hours of annual capacity, with future expansion expected to significantly increase throughput as additional production stages come online. The site is also intended to support certification standards such as ISO 9001 and AS9100, reinforcing its focus on aerospace and high-reliability use cases.

The company was founded in 2025 and is headquartered in Ann Arbor, where it is building its core research, engineering, and production operations. Its leadership team includes industry veterans with experience in battery development and advanced manufacturing. EGI Battery’s strategy centers on combining silicon-rich anode technology with scalable manufacturing processes tailored for high-performance applications.

In addition to aerospace and defense markets, EGI Battery is targeting robotics and emerging electrification sectors, where demand for compact, high-energy battery systems continues to grow. The company is also developing application-specific battery formats designed in collaboration with OEM partners, allowing customization based on system-level requirements.

TSV Capital’s participation in the round highlights increasing venture interest in domestic battery manufacturing and energy security technologies. Family office investors joining the round further underscore growing private capital involvement in industrial deep-tech sectors, particularly those aligned with national infrastructure and defense priorities.

With the new funding, EGI Battery plans to expand its workforce, scale production capacity, and strengthen its supply chain partnerships to support long-term commercialization. The company is also working toward increasing the proportion of NDAA-compliant materials in its batteries, aiming for higher domestic sourcing standards as it scales.

As global demand for advanced energy storage continues to rise, EGI Battery is positioning itself as a domestic supplier of high-performance lithium-ion technology for critical applications. With its seed funding secured, the company is now focused on moving from early-stage production to larger-scale manufacturing while expanding its footprint in the U.S. advanced battery ecosystem.
