GM’s Secret Battery Bet: New Tech Promises Longer Range and Lower EV Prices by 2028

Game-Changing GM Battery Will Deliver Cheaper, Longer-Range EVs by 2028—Here’s How It Works

GM and LG Energy Solution are set to unveil a breakthrough battery tech that could slash EV prices and boost ranges by the end of the decade.

General Motors is gearing up to unleash a revolutionary battery technology that could transform the entire electric vehicle landscape. Thanks to a decade of behind-the-scenes engineering and a pivotal partnership with LG Energy Solution, GM’s lithium manganese-rich (LMR) battery pack is now poised for real-world use by 2028.

This innovation aims to break through longstanding roadblocks like battery lifespan and voltage decay, which have slowed the race for affordable, long-range EVs. Now, after integrating advanced dopants, smart coatings, and creative particle engineering, GM claims its new LMR cells will combine high capacity, low cost, and “impressive range”—directly tackling pain points faced by drivers.

What Makes GM’s LMR Battery Different?

Unlike existing nickel-manganese-cobalt or lithium-iron phosphate (LFP) batteries, LMR batteries use a unique blend of materials for their cathodes. By tweaking the atomic recipe, GM scientists have not only improved energy density but also extended battery life—a historic weakness in older formulas.

And the changes go deeper than chemistry. Swapping common “pouch” cells for sleek, rectangular prismatic ones, GM slashes the number of battery components by up to 75%. Less hardware means lighter, cheaper packs and more room for active material to store energy.

How Does This Tech Shape EV Costs and Performance?

Today, GM’s electric SUVs and trucks—like the Silverado EV ($55,000 to $91,000) and Equinox EV (from $33,600)—still put EVs beyond many families’ budgets. But with LMR chemistry and streamlined prismatic cell design, materials and manufacturing costs tumble. According to GM’s top battery engineers, these savings will trickle down to buyers, making EVs “more affordable than ever.”

At the same time, GM is maintaining its edge in range. The Chevrolet Silverado EV Work Truck already travels up to 492 miles on a charge, and with LMR packs, future models could stretch those numbers even further.

Q: Do LMR Batteries Help the Climate (and Your Wallet)?

Absolutely. Research from the U.S. Department of Energy shows that every electric mile prevents thousands of pounds of carbon pollution—crucial for cities like Detroit and beyond. Tailpipe emissions are linked to health threats ranging from asthma to cancer, so reducing them benefits everyone.

Drivers can also pocket up to $1,500 a year in savings by ditching gas and avoiding the maintenance headaches of combustion engines. Pair your EV with rooftop solar panels, and you can fuel up for free from the sun while shrinking your carbon footprint. For rebates and rooftop quotes, check EnergySage.

What’s Next for GM—and the American EV Market?

GM isn’t figuring this out alone. It’s part of an eight-brand alliance planning to deploy over 30,000 new fast-charging stations across the country by 2030, making EV adoption easier coast to coast. Soaring sales—nearly 300,000 EVs sold in Q1 2025, up 11.4%—mean demand for smarter, cheaper batteries is at an all-time high.

While other automakers explore everything from potassium-based packs to even recycled cow hair for battery breakthroughs, GM is betting big that LMR chemistry will set a new gold standard for mainstream EVs.
