GM Plans LMR Prismatic Batteries From LG Energy Solution Joint Venture for Fourth-Generation EV Platform
GM outlined its fourth-generation EV platform at the GM Forward event in New York on October 21 local time. The platform will use lithium manganese-rich (LMR) prismatic cells to be manufactured by Ultium Cells, its joint venture with LG Energy Solution, in Spring Hill, Tennessee.
GM’s design target is 33% greater energy density than LFP batteries at a comparable cost. Combining the new batteries, propulsion systems and aerodynamics, the company also targets approximately 20% more driving range per kilowatt-hour than its current vehicles.
The new drive units are designed with 40% fewer internal components, while the electrical architecture reduces wiring length by 30%.
