GM’s Home-Grown Battery Bet Looks Strong. Cost Is the Question.

The central question for GM and Ford investors this weekend is not which company makes better trucks. It is which battery strategy survives long enough to matter. General Motors is in the early stages of developing next-generation battery cells that the company believes can reduce U.S. dependence on China while boosting domestically sourced materials. That announcement landed alongside a pointed government attack on Ford: Transportation Secretary Sean Duffy sent a letter to Ford CEO Jim Farley urging the automaker to sever ties with two Chinese companies, citing national security concerns over Ford’s deepening reliance on Chinese technology and manufacturing.

The Bull Case for GM

The Detroit automaker is spending $900 million on new battery lab facilities at its global tech campus in suburban Detroit. The technology direction is more ambitious than a like-for-like swap of Chinese chemistry. GM’s battery VP Kurt Kelty told CNBC that “the potential for sodium-ion is just much greater than LFP,” citing performance across a wider range of temperatures and more cycles. GM is also pursuing lithium-manganese-rich cells: LMR cells are expected to deliver around 33 percent higher energy density than LFP batteries at a comparable cost level. Critically, GM says LMR cell production is intended to support more responsible sourcing of critical materials like lithium, graphite, and manganese from North America, addressing raw-material dependency rather than just rerouting it.

The political tailwind is real and, for now, durable. Duffy’s letter identified CATL as a company that appears on the Department of War’s list of banned companies and criticized Ford’s China ties, including agreements involving CATL and Geely. Ford pushed back hard, stating that Duffy’s letter was “a wrongheaded attempt to capture headlines at the expense of a company that has done more for American manufacturing than virtually any other in the nation’s history.” But the political pressure lands regardless of whether Ford’s rebuttal is correct, and GM helped engineer it: a GM source familiar with the company’s lobbying said it has supported tighter restrictions on business ties to China, and Crain’s Detroit Business reported that GM has backed language aimed at licensing-style arrangements like Ford’s CATL deal in Marshall.

The Bear Case for GM

GM’s domestic battery path is expensive, early-stage, and measured in years, not quarters. “We’re developing a supply chain such that, two years from now, three years from now, it will be domestic,” Kelty told CNBC. That is an honest timeline and a commercially uncomfortable one. Meanwhile, Ford says its Michigan project is already producing full LFP prismatic cells and is on track to ship batteries in 2026, positioning it to be the first to deliver LFP batteries made in the U.S. for mainstream consumer automotive use.

The cost math also complicates GM’s position. U.S. battery project announcements saw about $11 billion in cancellations during 2025, reflecting market volatility and the difficulty Western companies face in securing long-term capital for new battery chemistries amid shifting government policies. GM itself has been inconsistent: the company has disclosed roughly $7.6 billion in EV-related charges in the second half of 2025 tied to its EV strategic realignment, including impairments and cash costs such as supplier settlements and contract cancellations. And while GM publicly condemns Ford’s CATL arrangement, it is not clean on the same issue: GM has said it plans to source LFP cells from CATL for the next-generation Chevrolet Bolt as a pragmatic step to introduce lower-cost batteries into its lineup quickly, with the Bolt slated to reach dealers in 2026. The credibility of GM’s “we build it here” message takes a hit when the company is simultaneously importing the competitor chemistry it condemns.

There is also a technology risk specific to sodium-ion. In 2026, CRU Group said it has tracked 370 GWh of announced sodium-ion cell production capacity, with much of the announced buildout centered in China, meaning GM risks building domestic expertise in a chemistry where China again dominates manufacturing scale.

Where the Evidence Leads

Seven Chinese companies together controlled 72.8 percent of the global EV battery market between January and July 2026, with CATL alone accounting for 39.9 percent. Competing against that concentration through domestic R&D is a decade-long project, not a two-year one. Battery expert Sam Abuelsamid noted that it will likely take years to domesticate a battery supply chain, and China continues to develop and produce new types of chemistries, including sodium-ion, in the interim.

GM’s long-term bet is intellectually defensible and politically fortified for as long as this administration holds. But Ford’s near-term cost advantage is real: cheaper licensed chemistry and cells moving through a Michigan line that Ford says is on track to ship batteries in 2026. The bear case for GM is not that its technology is wrong. It is that by the time GM’s domestic sodium-ion or LMR cells reach volume production, the political climate that made Ford’s CATL ties toxic may have shifted, and Ford will have banked the margin savings in the interim. Watch GM’s Spring Hill LFP conversion timeline and any congressional action on the CATL licensing rules for the clearest read on which path is actually winning.
