SHERIDAN, WYOMING – May 13, 2025 – Drivers looking for longer range and lower costs in electric trucks and SUVs have exciting news on the horizon. General Motors and LG Energy Solution are teaming up to launch a groundbreaking lithium manganese-rich (LMR) prismatic battery cell technology that promises big leaps in EV performance — and it’s made with American innovation at its core.
A New Kind of Battery Built for Bigger Adventures
GM’s push to electrify the roads just got a major boost with this new LMR battery breakthrough. Unlike traditional EV batteries that rely heavily on expensive materials like cobalt and nickel, these new cells use a higher proportion of manganese — a more abundant and affordable resource.
This smart switch helps keep costs down while supercharging performance. The new prismatic cells pack 33% more energy density than today’s best lithium iron phosphate (LFP) cells, offering a smart mix of power, range, and affordability.
“We’re pioneering manganese-rich battery technology to unlock premium range and performance at an affordable cost, especially in electric trucks,” said Kurt Kelty, GM’s VP of battery, propulsion, and sustainability.
What This Means for Drivers
For consumers, this could translate to trucks and SUVs with:
- Over 400 miles of range on a single charge
- Lower battery pack costs
- More cargo space and better performance thanks to prismatic cell efficiency
- A wider range of electric vehicle choices
That means fewer stops, more savings, and the freedom to go farther — whether you're commuting to work or heading off the grid for a weekend escape.
When and Where You’ll See It
The new LMR battery cells are expected to start pre-production in late 2027 at an LG Energy Solution facility, with full commercial production in the U.S. by 2028. Validation of the final design will take place at GM’s Wallace Battery Cell Innovation Center in Warren, Michigan.
This timeline puts GM on track to become the first automaker to use LMR batteries in EVs, expanding the company’s already leading electric lineup.
Decades of Research, One Breakthrough Moment
The LMR technology isn’t just new — it’s the result of a decade of research and development. GM began exploring manganese-rich lithium-ion cells back in 2015, and LG Energy Solution has been patenting the chemistry since 2010, now holding over 200 global patents in the space.
“We’re excited to introduce the first-ever LMR prismatic cells for EVs, the culmination of our decades-long research and investment in the technology,” said Wonjoon Suh, executive VP at LG Energy Solution.
The companies have overcome legacy challenges in LMR chemistry, including durability and performance, to bring a product that’s not only powerful but also sustainable.
A Boost for American Manufacturing and Clean Energy
Beyond the road, this innovation also powers up American jobs and sustainability efforts. The LMR cells will be integrated into GM’s U.S.-based battery production network and rely on responsibly sourced materials — like lithium, graphite, and manganese — from North America.
This strengthens domestic supply chains and helps reduce dependency on overseas materials, aligning with growing consumer demand for cleaner, more ethical electric vehicles.
Looking Ahead
With the LMR prismatic cell poised to hit the market in just a few years, GM and LG Energy Solution are showing what’s possible when cutting-edge technology meets practical consumer needs. It's not just about making EVs better — it's about making them smarter, more affordable, and ready for the real world.
