GM will continue to leverage the Ultium Cells plants in Warren, Ohio, and Spring Hill, Tennessee, which produce pouch battery cells, to meet growing demand for its electric vehicles.
Prismatic cells feature a flat, rectangular shape with a rigid enclosure, allowing space-efficient packaging within battery modules and packs.
That approach can reduce EV weight and cost while simplifying manufacturing by reducing the number of modules and mechanical components.
LG Energy Solution has experience with prismatic cell production and an extensive patent portfolio in battery design and manufacturing technologies, including packaging.
GM is embracing a technology-agnostic approach to battery cells to optimize range, performance, and charging speed, improving the experience for every EV driver.
Ultium Cells has created thousands of jobs in the U.S., including Ohio and Tennessee.
The battery cells produced at Ultium Cells plants power GM’s latest EVs, including the Chevrolet Silverado EV, GMC Sierra EV, Cadillac LYRIQ, Chevrolet Blazer EV, and Chevrolet Equinox EV, as well as the GMC HUMMER EV Pickup and SUV.
