Why GM’s Wild New Battery Could Slash EV Costs and Supercharge Range by 2029
General Motors’ breakthrough lithium manganese-rich battery tech could transform electric vehicles by 2029—here’s what drivers need to know.
- GM’s new LMR battery set for debut by 2029
- Chevrolet Silverado EV boasts up to 492-mile range
- EV sales in the US jumped 11.4% in Q1 2025
- Prismatic cell design could reduce battery components by up to 75%
DETROIT – In a bold leap forward for electric vehicles, General Motors (GM) announced that its groundbreaking battery project—years in the making—will produce a commercially viable lithium manganese-rich (LMR) battery pack before the decade is out. This advancement, made possible by a tight-knit partnership with LG Energy Solution, could fundamentally change what drivers expect from electric vehicles: more range, lower costs, and a path to easy ownership.
After years of engineering challenges, such as increasing battery lifespan and maintaining consistent voltage, GM’s tech experts are touting LMR’s phenomenal potential. Lithium manganese-rich batteries aren’t just a mouthful—they might be the secret recipe for affordable, high-range EVs that can finally go the distance for the masses.
Q: What Makes GM’s LMR Batteries a Potential Game Changer?
This next-generation battery relies on a unique blend of dopants, innovative coatings, and precise particle engineering. The LMR formulation becomes the cathode—the battery’s heart—helping ions rush back and forth more efficiently. This creates a power pack that can deliver far more “go” for your dollar.
While GM isn’t alone in the battery race (competitors are toying with everything from lithium-iron phosphate to even potassium and cow hair), its engineers believe LMR packs outclass rivals thanks to a harmonious blend of high capacity and reduced material costs. The automaker stresses that the technology could finally bring down EV sticker prices, opening options for a much wider audience.
How Will These Batteries Make EVs Cheaper?
One of the key innovations is a switch to rectangular “prismatic” cells. Unlike traditional pouch designs, prismatic cells dramatically slash unnecessary parts—by up to 75% for battery modules and up to 50% for the total pack. This doesn’t just mean savings for GM; it could put EVs within reach for millions of drivers.
For context, today’s Silverado EV costs between $55,000 and $91,000, and the Chevy Equinox EV starts at $33,600. GM’s goal: use LMRs to drop these numbers—and make range anxiety a thing of the past.
Q: How Far Can You Go on a Charge?
If you’re tired of worrying about your next charge, GM’s battery tech brings good news. The Chevrolet Silverado EV, already rated as the longest-range electric truck, delivers up to 492 miles per full charge according to official government tests. That’s a road trip on a single stop!
How Do EVs Benefit the Environment—and Your Wallet?
Adopting electric vehicles doesn’t just cut tailpipe emissions that are linked to cancer and respiratory issues—it can translate to concrete savings. According to Department of Energy figures, EVs can save you up to $1,500 a year in fuel and maintenance. Charge your EV from a home solar array and those savings grow, all while shrinking your carbon footprint. EnergySage connects homeowners with vetted solar incentives and installers—plus both solar and EVs still qualify for major tax credits.
What’s Next: Fast-Charging and a Booming EV Market
EV adoption is surging. The first quarter of 2025 saw nearly 300,000 EVs sold in the U.S.—an 11.4% rise over last year. To meet this demand, GM, alongside an alliance of eight major brands, is powering up a nationwide charging network. The plan: 30,000 fast-charging stations launching over five years, ensuring drivers never feel stranded.
