GM and LG Energy Solution to Pioneer LMR Battery Cell Technology

General Motors aims to become the first automaker to deploy LMR battery technology in electric vehicles. This new battery cell technology builds on GM's legacy of pioneering innovations, such as the small-block V8 engine and hands-free Super Cruise. The Ultium Cells joint venture between GM and LG Energy Solution is set to commence commercial production of LMR prismatic cells in the United States by 2028. The new battery cells are expected to provide a 33% higher energy density compared to the best-performing lithium iron phosphate cells, while maintaining comparable costs.

LMR battery cells utilize a greater proportion of manganese, which is more affordable than cobalt, a key component in traditional batteries. By reducing reliance on expensive materials, GM and LG Energy Solution aim to offer electric trucks with over 400 miles of range at a lower cost. This breakthrough not only promises to make electric vehicles more accessible but also supports GM's goal of advancing American battery innovation and creating jobs.

The development of LMR battery technology is a culmination of years of research and investment. GM began exploring manganese-rich lithium-ion battery cells in 2015, and significant advancements have been made in collaboration with partners. LG Energy Solution's extensive portfolio of over 200 patents in LMR technology underscores their leading role in this innovation. The advanced cathode materials and cell assembly processes developed by GM engineers are pivotal in overcoming the performance and durability challenges historically associated with LMR batteries.

Integrating LMR battery technology into GM's supply chain underscores strategic investments in domestic battery production. The collaboration reinforces the responsible sourcing of critical materials like lithium and manganese from North America. This strategic approach not only strengthens GM's battery ecosystem but also aligns with broader corporate sustainability goals.

The partnership between GM and LG Energy Solution exemplifies the companies' joint commitment to offering diverse EV options to consumers. By leveraging their combined expertise, they are poised to drive the future of transportation with sustainable and innovative battery solutions. This technological leap promises to reshape the electric vehicle landscape, providing consumers with more choices and promoting environmental stewardship.
