Advanced Batteries for America · Ann Arbor, Michigan
BRINGING POWER TO ALL
EGI Battery designs, distributes, and manufactures advanced lithium-ion battery cells in the United States, with production operations based in Michigan.
Building NDAA Compliant Cell Production
Manufacturing NDAA Compliant Cells in Michigan
At our Zeeb Campus in Ann Arbor, Michigan, we’re building domestic cell manufacturing that begins production in 2027. Today, we supply advanced pouch cells in volume to drone, robotics, electric aviation, and light mobility programs.
Innovating Manufacturing
We are rethinking how cells get made, with compact formation and modular process equipment that cut the floor space, energy, and time a conventional line requires.
Scaling Production
Our Zeeb Campus operates with 20,000 square feet of highly automated production with room to expand to 130,000 sq. ft. as we scale toward full production.
Proven Expertise
Our team of engineers and operators have scaled cell production at some of the largest battery manufacturers in the world.
The EGI Cell Portfolio
High energy density cells
for demanding platforms
Our pouch cells are built for platforms that can’t afford to come up short: high energy, high power, and capacity that holds through hundreds of cycles. They’re sized to drop into cylindrical pack configurations already in use, so a pack built from our cells fits the space your platform was designed around.
SAE Standard Form Factor
No Compression Required
Available Today in Volume
High energy density
Every gram of pack weight carries more energy, so you get longer run time and greater usable payload on the same platform.
Long cycle life
Our cells hold capacity through hundreds of full charge cycles, providing reliable performance and fewer replacements.
No compression required
Our cells don’t require compression hardware to hit rated performance. That’s mass you don’t carry, freeing weight for payload or range.
Wide operating temperature
Select cells are rated for discharge from -40°C to 60°C, ensuring consistent delivery across cold starts, hot enclosures, and everything between.
High discharge capability
Our cells sustain high continuous current with strong pulse capability, so the pack delivers on hard climbs, heavy lift, and sudden acceleration.
more power at low state of charge
Low internal resistance at low charge limits voltage sag, so you can still pull landing power late in the flight and use more of the capacity you carry.
A Cell for Every Requirement
Multiple chemistries, same footprint. Our portfolio covers the full range from high energy to high power, so you can choose the cell tuned to what your platform needs and move between them later without changing the pack.

Built to a standard we helped define
Our cells are built to the SAE JA1016 standard geometry our team helped develop, sized to fit the same space as existing cylindrical packs. A pouch pack built with our cells replaces your current cylindrical pack with no redesign, and because pouch cells use that space more efficiently, the same volume carries more energy.
Standard Geometry
Fewer Cells per Pack
Higher Energy Density
Markets We Power
Built for platforms where
failure isn’t an option
Drone
High energy density in the sizes drone packs already use, for longer flights and heavier payloads without redesigning the platform.
Robotics
High continuous and pulse current with voltage that holds as the pack runs down, so a robot works the same at the end of a shift as at the start.
eVTOL
High energy density paired with sustained discharge, sized to the flight energy and mass budgets electric aircraft carry.
E-Mobility
High energy density with long cycle life, keeping range and cost per mile predictable over the life of the vehicle.
Talk With an Engineer
Our engineers work with you to match the right cell to your platform. We partner with pack integrators across the industry to build it into a finished pack.
