General Motors is working with LG to produce lithium manganese (LMR) batteries for its electric trucks and SUVs. The new chemistry is more safe, more energy -dense, and less expensive than current technology, the automated maker says.
GM aims to become the first automaker to deploy LMR batteries in EV, which plans to start trade production in the United States by 2028. Last month, Ford announced that she would start adopting LMR batteries for her EV, but not until 2030.
In EV batteries, cathode, or negative electrodes, are usually made with NCM – nickel, cobalt, and magnesium. Is cobalt A key component in this mixtureBut it is also the most expensive content of the battery and Mining under these conditions that often violate human rightsIt is called “batteries’ blood diamond”. As a result, other companies like GM and Tesla are running away to make a coal -free battery. As an alternative, LMR battery cells use more affordable and high proportion of manganese, while also providing high capacity and energy density.
GM has typed about 300 300 full -sized LMR cells as it has worked with LG Energy Solution to break the code in chemistry.
“We like to joke that it’s cheaper like dirt,” says Andrew Ary, a GM battery engineer.
The current crop of GM uses high nickel batteries of electric shivs and cadelox, which provides enough energy to a extent of about 300-320 miles. GM says new LMR batteries are less than their livestock performance due to their domestic shape, which enables up to 400 miles. Perizatic cells are packed flat in rigorous cases and it is generally believed that they are less complicated for preparation than cylindrical cells.
It is hoped that low complexity and cheap content will lead to low -cost EVs, which has been an important challenge for the auto industry’s change in electrical vehicles.
“EV rate growth is really up to how we can reduce costs over time,” says GMKVP for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries for batteries. “And it’s the biggest lever we have. The batteries make up about 30 to 40 percent of the cost of cars. And if you can leave it significantly as we are here, it becomes a low price for the user.”
The cells will be manufactured by a joint venture of ultim cells, GM and LG, which is expected to predict at the end of 2027. The final design will be verified at the GM battery cell development center in Michigan warns, which opens earlier this year, as well as the LG energy solution. Last year, GM sold his stake to LG at a Lancing -based EV battery factory.
“We like to joke that it’s cheap like a mess.”
GM says LMR batteries are the result of “decades of research and technology investment” that will move it ahead of its rivals. GM began researching manganese -rich lithium -ion battery cells in 2015, including prototyping LMR cell at the Walis Battery Cell Innovation Center.
There may be some challenges to create LMR batteries. LMR content is known to experience significant loss of capacity, which can reduce driving limits and thermal stability.
GM says he is aware of these challenges and is confident that he can innovate the production process to minimize these risks. Engineers from the car maker say that LMR batteries were expected to perform the same as the first -generation of GM’s first -generation of batteries, even at high temperatures.
President Donald Trump’s trade war is racing to reduce the costs of EVA, which is the most important producer of the world’s EV batteries, producing more than 70 % of the global lithium -ion battery.
“We expect our content for the battery supply chain to increase between the localization now and 2028,” says the Cally. “And LMR is part of this story, because we get more content locally.”
