Detroit’s Battery Revolution: GM and LG Crack the Code on Affordable, Ultra-Long-Range EVs
General Motors teams with LG Energy Solution to unveil a lithium manganese-rich EV battery expected to shake up the industry by 2028.
- LMR breakthrough: Promises lower costs and 492+ mile ranges
- 75% fewer parts: Thanks to innovative prismatic cell design
- 11.4% rise: Q1 2025 U.S. EV sales compared to 2024
- 30,000 charging stations: Planned by major automakers alliance
The race to dominate the electric vehicle (EV) market just shifted into high gear. General Motors, in partnership with LG Energy Solution, is preparing to unleash a new breed of lithium manganese-rich (LMR) battery that could bring mainstream EV ownership to more Americans—but with greater range and affordability than ever before.
The Game-Changing LMR Breakthrough
After nearly a decade of research beginning in 2015, GM’s advanced battery cell engineering team—led by Kushal Narayanaswamy—has overcome the obstacles that plagued LMR technology. Challenges like short lifespans and gradual voltage decay have given way to promise, thanks to a blend of innovative “dopants, coatings, and particle engineering.”
By focusing on a manganese-rich cathode and a cutting-edge rectangular prismatic cell design, GM’s battery experts have slashed the number of non-essential parts. The result? Battery module components drop by 75%, total pack components by 50%, and future EVs are primed to be both cheaper and roomier.
Why Is This Battery Different?
Most current batteries rely on expensive metals like nickel, cobalt, or aluminum. LMR technology flips the script with reduced reliance on costly materials, translating to impressively low-cost, longer-range electric vehicles.
With manufacturers like Tesla exploring lithium-iron phosphate (LFP) and others dabbling with even wilder ingredients (think potassium or even cow hair), GM’s approach seems ready to leapfrog the competition by balancing price, practicality, and performance.
Q: When Will These Next-Gen Batteries Hit the Road?
GM signals commercial LMR packs will be ready by 2028, positioning the company as a leader in the race for affordable, long-range EVs. The timeline fits the rapid expansion of the U.S. EV market, which saw almost 300,000 vehicles sold in Q1 2025, up more than 11% from last year, according to Cox Automotive.
How Will Prismatic Cells Change EV Design?
Traditional “pouch” batteries are getting the boot. GM’s prismatic cells not only reduce parts and weight but could pave the way for slimmer, more creative vehicle interiors—and faster, cheaper manufacturing.
Q: What’s the Potential Range and Cost Impact?
GM’s Silverado EV Work Truck already boasts a 492-mile range per charge, a number set to be matched—or beaten—by upcoming LMR-powered vehicles. For shoppers, the promise is clear: lower sticker prices (the base Chevy Equinox EV currently starts at $33,600; Silverado EVs can top $90,000). The LMR innovation aims to push those numbers down, widening EV accessibility.
How Much Can Owners Save?
Switching to an EV can save drivers up to $1,500 per year in fuel and maintenance, according to the Department of Energy. Further savings are possible when pairing EVs with a rooftop solar setup, unlocking clean miles provided by the sun. Seeking incentives? EnergySage is a popular starting point for navigating rebates and finding solar or EV installers.
Q: Can I Charge Easily?
Infrastructure is expanding fast. GM’s alliance with seven other major automakers aims to add 30,000 rapid charging stations across the U.S., removing “range anxiety” and letting drivers plan longer trips with confidence.
How Is This Good for the Planet—and Our Health?
EVs help eliminate thousands of pounds of climate-warming emissions—even in regions reliant on fossil-fueled electricity. Reduced tailpipe pollution can slash cancer risks and improve air quality, experts at the EPA confirm.
