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

EGI 35 Ah pouch cell

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.

EGI 9.4 Ah and 35 Ah standard form factor cells

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.

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.
