General Motors (GM) and LG Energy Solution are extending their 14-year battery technology partnership to include prismatic cell development. This collaboration supports GM’s strategy to diversify its EV battery supply chain, leveraging multiple chemistries and form factors for its future electric vehicles (EVs). GM will continue to utilize the Ultium Cells plants in Warren, Ohio, and Spring Hill, Tennessee, which produce pouch battery cells, to meet growing EV demand.
Prismatic Battery Cell Technology for Enhanced EVs
Prismatic cells offer a flat, rectangular shape with a rigid enclosure. This design allows for space-efficient packaging within battery modules and packs. According to the press release, this approach can contribute to reduced EV weight and cost, while simplifying manufacturing by reducing the number of modules and mechanical components. LG Energy Solution brings experience in prismatic cell production and an extensive patent portfolio on battery design and manufacturing technologies, including packaging. GM’s technology-agnostic approach to battery cells aims to optimize for range, performance, and charging speed, ultimately improving the EV driver experience.
Leadership Statements on the Expanded Partnership
- Kurt Kelty, GM vice president of battery cell and pack: “Together with LG Energy Solution, we’ve built Ultium Cells into one of the largest battery cell manufacturers in North America, creating thousands of advanced technology jobs in the U.S. and powering our diverse EV portfolio. We’re focused on optimizing our battery technology by developing the right battery chemistries and form factors to improve EV performance, enhance safety, and reduce costs. By extending our partnership with LG Energy Solution, we’re taking an important step toward these goals.”
- Wonjoon Suh, executive vice president and head of the company’s Advanced Automotive Battery division: “LG Energy Solution is proud to be expanding its relationship with one of its strongest partners. Together with GM, we’ve already made tremendous progress. We look forward to deepening our collaboration to drive the right chemistry and battery combinations for continued growth in the EV market.”
Ultium Cells: Powering Current GM EV Models
Ultium Cells has created thousands of jobs in the U.S. in Ohio and Tennessee. The battery cells produced at these plants power GM’s current EV models, 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.
