Overview

• General Motors and LG Energy Solution plan to begin commercial production of LMR prismatic battery cells in the U.S. by 2028, following preproduction in late 2027.
• The LMR chemistry achieves a 33% higher energy density compared to lithium iron phosphate (LFP) cells at a comparable cost, enabling over 400 miles of range for electric trucks and SUVs.
• The batteries reduce reliance on expensive cobalt and nickel, using 60–70% manganese, which is more abundant and cost-effective.
• The prismatic cell design simplifies manufacturing by reducing battery pack components by 50%, lowering weight and production complexity.
• GM aims to localize battery material sourcing, with manganese processing planned at a facility in Louisiana, to enhance supply chain resilience and cost efficiency.
