General Motors and LG Energy Solution are extending their 14-year battery technology partnership to include prismatic cell development.?GM expects the prismatic cell technology developed under the agreement to power future GM electric vehicles, as part of the company’s strategy to diversify its supply chain, leveraging multiple chemistries and form factors.

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, which allows for 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 both experience with prismatic cell production and an extensive patent portfolio on battery design and manufacturing technologies, including packaging.??
