EGI Battery Establishes Advanced Lithium Ion Manufacturing Campus in Michigan

EGI Battery has announced the establishment of its first U.S. manufacturing campus in Ann Arbor, Michigan, marking a significant step in the company’s plan to expand domestic production of high performance lithium ion pouch cells. The Zeeb Road campus will serve as the operational foundation for EGI’s long term manufacturing strategy, supporting mission critical applications across drones, electric aviation, aerospace systems, and emerging robotics platforms.

Company leadership emphasized that the facility is designed to meet National Defense Authorization Act alignment requirements, positioning EGI to supply secure, U.S. manufactured batteries for defense and aerospace customers seeking resilient supply chains.

Phased Expansion Model Supports Scalable Production

The initial footprint includes approximately 15,000 square feet dedicated to manufacturing and laboratory operations, along with 5,000 square feet of office space. The site provides access to a total of 130,000 square feet for future expansion. Site Acceptance Testing is targeted for the end of the first quarter of 2026, with production expected to begin in the third quarter.

Phase 1 operations will focus on electrolyte filling, aging, sealing, folding, formation, and grading. The initial line is designed for one part per minute throughput, supporting up to 300,000 cells annually at full three shift operation, equivalent to roughly 40 megawatt hours of annual capacity based on EGI’s 35 amp hour NMC pouch cell.

Phase 2, planned for 2027, will vertically integrate electrode making, cell assembly, and final formation. Throughput is expected to double to two parts per minute, supporting up to 600,000 cells annually for approximately 80 megawatt hours of capacity. At full ramp, the campus is projected to support around 100 jobs by 2028.

Technology Platform Tailored for Aerospace and Defense

EGI’s product portfolio includes silicon enhanced and graphite anode chemistries, along with custom battery formats designed to meet OEM system requirements. The company’s modular manufacturing strategy is intended to support high yield production while maintaining flexibility for application specific designs.

The focus on NDAA alignment reflects the growing demand for domestically sourced energy storage solutions in aerospace and defense programs. EGI is building its processes to comply with ISO 9001 and AS9100 quality standards and aims to achieve at least 95 percent NDAA compliant materials by cost in 2028.

Regional Support for Next Generation Battery Manufacturing

Michigan based MI HQ CEO Mark Smith noted that EGI’s investment strengthens the state’s position in advanced battery innovation and supports the broader industrial ecosystem developing around next generation energy storage technologies.
