US automaker GM is extending its 14-year collaboration with South Korean battery maker LG Energy Solution to develop prismatic cell technology.
GM expects the cells that the companies develop to power its future EV models, as part of its strategy to diversify its supply chain, using multiple chemistries and form factors. GM will continue to use the pouch battery cells produced at the companies’ Ultium Cells joint venture plants in Warren, Ohio and Spring Hill, Tennessee.
Prismatic cells are flat and rectangular in shape and have a rigid enclosure, which saves space within battery modules and packs. This 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 on battery design and manufacturing technologies, including packaging.
“Together with LG Energy Solution, we’ve built Ultium Cells into one of the largest battery cell manufacturers in North America, powering our diverse EV portfolio,” said Kurt Kelty, GM VP of Batteries. “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.”
