GM CEO Ms Mary Barra said that GM is already useing cylindrical batter cells for EVs sold in China, as compared to the pouch-style battery cells currently produced in North America. The Chinese-spec Cadillac Lyriq already uses cylindrical-style GM batteries.Although these cylindrical batteries carry the GM Ultium battery branding, the technology differs from the pouch-style batteries produced in the US. The Chinese-market batteries use NMC battery chemistry, with cells produced by CATL, as compared to GM-LG Energy Solution joint venture running Ultium Cells in North America.Some of the advantages of a cylindrical battery design over a pouch-style battery are reduced costs and more streamlined production, both of which would greatly benefit GM as it moves to ramp up EV production this year. Rival EV producer Tesla already uses cylindrical batteries, specifically 4680 cells. Stellantis, BMW, and Volvo are also reportedly poised to use cylindrical battery design in future EV models.
