General Motors (GM) and LG Energy Solution have teamed up to shake up the electric vehicle (EV) scene with a fresh batch of lithium manganese-rich (LMR) prismatic batteries that could change how electric trucks and SUVs roll. These new cells pack about 33% more energy density than the best lithium iron phosphate (LFP) batteries on the market—a crucial upgrade for those looking to juice up their EVs with longer range at a cost that won’t bust the bank. This advance takes aim at one of EVs’ toughest nuts to crack: stretching driving range without breaking the budget.
The EV market is expanding fast, but it’s still wrestling with a trio of troublemakers—range anxiety, affordability, and battery performance. Lithium-ion batteries reign supreme, but their hunger for pricey, supply-risky materials like cobalt and nickel keeps costs sky-high. GM is flipping the script by leaning on manganese, a cheaper and more abundant element, to craft batteries that not only hold more juice but also sidestep the usual supply chain headaches. This move fits snugly within GM’s broader game plan to build a diverse battery lineup as it pushes full speed ahead into an all-electric future across brands like Buick, Cadillac, Chevrolet, and GMC.
The crown jewel of this breakthrough? Those LMR batteries boast a 33% bump in energy density compared to top-tier LFP batteries. More energy density means squeezing more power into the same space or weight, translating directly to longer hauls per charge. GM projects most of its full-sized EV trucks and SUVs fitted with these batteries will clock more than 400 miles on a single charge—jumping well past many current EV offerings. For drivers commandeering larger vehicles that demand beefy batteries, this leap isn’t just numbers on a chart; it’s real-world freedom from the frequent pit stops for charging.
On top of that, the LMR technology plays nice with larger prismatic cell formats, which aren’t just about scale but also about streamlining production. Bigger cells mean fewer parts to assemble, like connectors and structural supports, chopping down complexity and cost in battery packs. This economic edge could ripple out, making EVs with these batteries more affordable without sacrificing the grunt under the hood.
What really shifts the game is how this tech balances power with price. GM claims these LMR batteries reach their high energy density without costing more than LFP batteries, which are known for being wallet-friendly and safer. By building batteries around manganese—a resource plentiful enough to keep prices steady—GM and LG could dodge the volatility that cobalt- and nickel-heavy chemistries have faced. That’s not just smart economics; it’s shielding future EV buyers from sudden price hikes sparked by material shortages or geopolitical drama.
The fact that manganese-rich cathodes might help craft batteries that last longer is icing on the cake. Early tests at GM’s Battery Cell Development Center suggest these batteries stay reliable and efficient through plenty of charge cycles. Longevity means drivers won’t need to swap batteries as often, trimming the total cost of ownership and waste down the road.
Zooming out, the ramifications of this breakthrough could reshape the EV battleground. Should GM hit commercial rollout by 2028 as planned, it’ll cement itself as a pioneer in EV battery innovation. This could push other automakers to follow suit, quickening the pace toward batteries that lean on sustainable, abundant materials without stealing performance. The gain here is especially meaningful for full-size electric trucks and SUVs, which have typically trailed behind smaller EVs in both reach and affordability.
The long-standing partnership between GM and LG Energy Solution, spanning over 14 years, shows the muscle of collaboration against the tough nuts of next-gen battery tech. Their work on LMR chemistry breaks from the nickel-cobalt-aluminum (NCA) and nickel-cobalt-manganese (NCM) molds that currently dominate, beefing up supply chain resilience and boosting technical flexibility.
For consumers, this could rewrite what they expect from long-range EVs, widening access to clean, efficient rides without the sticker shock. More practical still, shifting to manganese-rich batteries paves a path to greener production by cutting reliance on materials that carry heavier environmental or ethical costs.
Pulling it all together, the lithium manganese-rich batteries GM and LG are cooking up represent a major jump in EV battery tech. With a 33% hike in energy density, an eye on affordability, and commitments to sustainability, these batteries stand to unlock over 400 miles of range for full-sized EV trucks and SUVs without inflating costs. As they edge toward market debut by 2028, this innovation could drive a new era where long-range, affordable electric vehicles become the rule rather than the exception—making EVs a more appealing choice for a wider crowd and sparking a shift across the industry that’s been a long time coming.
