GM Battery – Inside General Motors’ Warren Tech Center, a new Battery Cell Development Center is built to turn its LMR battery chemistry from lab success into production—so EVs can reach the road with lower costs and an aggressive timeline that stretches to 2028.
At General Motors’ Warren Tech Center outside Detroit, the next step of the company’s electric future is housed in two plain, off-white boxes.
They don’t look like a turning point. The buildings measure 500,000 square feet in total and house GM’s new Battery Cell Development Center, a facility GM says is central to a $900 million bet on electrification—and to cutting EV battery costs by nearly 10%.
The push comes as GM tries to reboot a rollout that hasn’t matched the ambition. Last year. the automaker took a $1.6 billion charge after it reconfigured its EV production capacity and laid off thousands of workers. GM has also reportedly shelved, if temporarily, a refresh of its full-size EV trucks and SUVs.
Now, GM is trying to close the gap between promise and scale with a battery chemistry it wants to lean on heavily: LMR, short for lithium-manganese-rich.
Kurt Kelty. vice president of battery and sustainability at GM and the person who previously led battery technology at Tesla. has been explicit about where the company is putting its weight. “That is really going to be our bread and butter,” Kelty told TechCrunch. “That is going to be our main product line.”.
LMR is intended to replace the role that Ultium—GM’s current battery platform—has been playing. at least in lower and mid-end vehicles. Pressure on costs and a shifting battery landscape have forced GM to rethink its earlier plan built around NMC. nickel-manganese-cobalt. which GM has used in higher-end models.
GM’s earlier bet on NMC has been hit by rising materials costs and China’s dominance over key critical minerals, both of which have kept EV prices higher than expected. NMC won’t disappear at GM, but GM says it will be restricted to the automaker’s high-end vehicles.
LMR, GM says, is close enough on performance and cheaper enough to matter. The company says LMR is almost as energy dense as NMC, while costing comparably to cheaper chemistries like LFP—lithium-iron-phosphate—which power low-end models like the Chevrolet Bolt.
When GM introduced LMR last year. it said the chemistry could do something practical in real vehicles: in a truck like the Chevrolet Silverado EV. LMR should preserve most of the vehicle’s more than 400-mile range while slashing costs by at least $6. 000. GM also said the mid-range version could bring prices within spitting distance of the gas version.
But getting a new chemistry to work is only half the fight. Manufacturing gigawatt-hours worth of it is where many efforts break down, especially when the industry is moving fast and rival strategies keep shifting.
GM says it wants to get LMR vehicles on the road by 2028, and it needs the Battery Cell Development Center to make that timeline realistic.
The facility spans two buildings and is designed to function like a bridge between GM’s research and its production plans. GM opened its Wallace Battery Cell Innovation Center and its first gigafactory in 2022. but the company says what was missing was a way to connect breakthroughs from Wallace to factory floors in Tennessee and Ohio.
The BCDC—an internal name GM uses for the Battery Cell Development Center—plays that role. When fully operational, it will produce about 2,500 cells per day, or about half a gigawatt-hour per year. The process starts with batteries developed in small batches—about 30 to 50 per day—at the Wallace Battery Cell Research Center next door. where the company tests whether the chemistry is ready for production.
GM’s goal is to turn R&D recipes into something that survives commercial reality. Companies often don’t have the luxury of years of trial-and-error. and a McKinsey report cited in GM’s planning sets a benchmark: if a new chemistry can’t hit 85% yield within 18 months on a production line. it shouldn’t be considered commercially viable.
The mismatch is more than scale. Batteries that leave research facilities are small coin cells, but EV pack cells are closer to a small cutting board. Kelty described what that means in practice: “Once you learn how to make the recipe in Wallace. then you’ve got to figure out. well. how do you make this in high volume?” he said. “You really learn a lot going from that coin cell to the large format because it doesn’t transfer perfectly.”.
The BCDC is meant to make that “handoff” smoother.
A test run at the facility is expected to cost about $200,000—far less than at the full-size Ultium plant. GM says once the BCDC team is confident the process is dialed in. the transition to full production should be easier because the equipment is almost the same. “The equipment is almost the same between them. and so it shouldn’t be as hard of a handoff. ” Kelty said.
Even with those efficiencies, the BCDC is still a major operation. It is one or two orders of magnitude smaller than the 2.8 million-square-foot Ultium battery factory in Tennessee. The Ultium plant makes about 300,000 cells per year, or 45 gigawatt-hours’ worth. GM says the BCDC has fewer production lines. makes about a hundredth the number of cells. and its mixing tanks—where battery materials are blended—hold 40 liters instead of 2. 000. Still, GM describes the BCDC as an order of magnitude larger than the Wallace Center next door.
“The BCDC is intended to bridge the gap,” Mo Gallegos, head of BCDC at GM, told TechCrunch.
Behind the scenes, GM is also trying to compress time with digital tools. To cut costs further. the automaker has been working to simulate as many processes as possible using a variety of AI models. GM has invested heavily in computing power. and while no number is publicly pinned down. the company says it’s “national lab-scale.”.
GM has built physics-based models designed to simulate how changes to battery chemistry or production process will affect cell performance. GM says the LMR effort has already logged more than 150 million CPU hours. “On LMR. we’ve logged over 150 million CPU hours. ” Radu Theyyunni. director of global virtual electrification and powertrain at GM. told TechCrunch. “Most engine programs do not use that many core hours.”.
There’s also a digital twin of the entire BCDC. GM says it includes equipment control boards, wiring, and even the blades in the mixing tanks. Before entering the facility, GM had a reporter put on a VR headset to walk through the digital twin and follow the production line from start to finish.
As the BCDC has taken shape, GM says the digital twin has been used for practical troubleshooting. In one example. the team used it to determine whether the plans left enough clearance around equipment for regular operations and repairs. In another, they simulated the equipment’s control systems to ensure everything would behave as intended.
Gallegos described the value in plain terms: “Does the equipment run how it’s supposed to?. Does it run safely?. Is it doing all the things we think this control system is going to do?. That shortens our debug and ramp up time,” he said. GM says the simulations have saved the company millions of dollars.
The need to speed up is real. While the EV market in the U.S. has softened recently, globally it grew 20% last year. High oil prices and declining battery costs suggest the shift away from fossil fuels will continue, even if it happens unevenly.
GM’s bet is that if LMR can pass through the BCDC on time, the company can offer cost-competitive EVs with enough range to calm consumer anxiety. But first, LMR has to survive the scale-up process.
Gallegos expects the first batches to roll off the line later this year. Over the coming decade, GM says battery development will matter to automakers as much as engine development did across the last century.
Kelty often frames GM’s work as matching chemistry to mission. He says GM is developing “the right battery for the right application,” echoing an old slogan: “a car for every purse and purpose.”
LMR might be the BCDC’s first test, but GM’s message is clear—this center is being built for whatever comes next.
