General Motors announces breakthrough in EV battery cell technology, paving the way for more accessible, long-range electric vehicles in its truck and SUV lineup.

The 2025 Chevrolet Silverado EV currently offers up to 492 miles of range, but General Motors has pledged to unlock even greater distances at a lower price point. General Motors and LG Energy Solution have introduced the industry’s first lithium-manganese rich (LMR) prismatic electric vehicle battery cells, a breakthrough innovation in sustainable energy storage. The newly developed battery cells will power General Motors’ electric vehicle (EV) models, starting with various vehicles and SUVs.

General Motors will leverage Lithium-Manganese-Rich (LMR) electric vehicle (EV) battery cells to power its latest EV lineup.

General Motors aims to pioneer the use of lithium-metal rechargeable (LMR) batteries in electric vehicles, marking a significant milestone in its commitment to advancing sustainable mobility solutions.

General Motors and LG Electronics have jointly introduced their innovative LMR prismatic battery cell, boasting a remarkable 33% increase in power density compared to the industry-leading lithium iron phosphate (LFP) batteries at a competitive cost.

Currently, no electric vehicles (EVs) on the market utilize LMR batteries. General Motors believes that its reluctance to adopt electric vehicles stems from a noble intention, driven by the challenges posed by rapid battery degradation and voltage decline. The automotive manufacturer finally thinks it has found a solution.

General Motors has introduced the development of innovative battery cells, touted as a significant step forward in offering electric vehicles (EVs) that combine exceptional range and affordability. The Chevrolet Silverado EV WT boasts the industry’s longest range for an electric truck, boasting an EPA-estimated range of up to 492 miles in its 2025 iteration.

General Motors announces plans to incorporate brand-new battery cells in its forthcoming electric vehicle lineup and full-size sport utility vehicles. The company aims to deliver more than 400 miles of range by incorporating innovative battery cells, boasting crucial advancements in energy efficiency compared to its existing high-nickel pack.

“We’re revolutionizing the development of high-performance manganese-rich batteries to deliver exceptional range and efficiency at a competitive cost – specifically for electric vehicles,” said Kurt Kelty, General Motors’ Vice President of Battery, Propulsion, and Sustainability.

Due to its environmentally conscious design, the innovative technology proves particularly suitable for larger electric vehicles (EVs) and sport utility vehicles (SUVs). With their unique oblong shape, prismatic cells prove significantly more conducive for large-scale applications such as bundling in full-size vehicles and SUVs, surpassing the efficiency of traditional pouch cells in these contexts.

Since 2015, General Motors (GM) has devoted research efforts to battery cells featuring manganese-rich cathodes. By the end of 2024, the company had investigated an extensive collection of large-format prismatic cells, equivalent to approximately 1.4 million miles of electric vehicle driving.

The statement underscores that LMR enables General Motors to deliver EVs with premium range at a significantly lower cost.

The Ultium Cells, a joint venture between General Motors (GM) and LG, is poised to commence mass production of lithium-ion rechargeable battery modules, specifically large-format pouch cells, at its US facility by 2028.

Just two weeks after crosstown rival Ford unveiled its plans to develop “breakthrough” lithium-metal rechargeable (LMR) batteries, enabling affordable electric vehicles for the masses.
