General Motors has It has just announced its latest and likely final song in what now seems to be a three -sided strategy of cellular chemistry to feed a series of several EV to the end of the decade and later.
GM today stated that at Spring Hill, Tennessee, it will build budget-friendly lithium iron phosphate battery cells (LFP), starting from the end of 2027. The cell plant in the Spring Hill elaborate is owned and supported by Ultium Cells, Company battery battery GM with Energy LG solution. The GM assembly plant in the same elaborate builds Cadillac Lyriq and Acura ZDX SUV -Y.
For Kurt Kelta, Vice President for the GM for battery, propulsion and sustainable development, the company diversified its earlier strategy “one cell for all EVs”. Kelta was employed in February 2024 after his stay in Tesla and Panasonic and is widely respected in the industry.
LFP cells made by Ultium are expected will be used in the 2026 Chevrolet Bolt EV, which GM should reveal within two to three months. Before the end of this year, it will enter production at the Kansas plant. For the first two years he will have to employ LFP cells imported from another LG plant – just one in South Korea. This imported GM allows to obtain inexpensive iron phosphate batteries for American roads for a full three years before the next cell chemistry, called LMR, which, he claims, costs no more than LFP, but has a higher energy density.
Despite this, the transformation of the plant – indefinite cost – building LFP cells suggests that they will be used for a while in the composition.
LMR promise came
Until now, all EV GM after EV Chevrolet EV 2017-2023 used nickel-Man-Cobalt-aluminum (NMCA) cells. These have the most energy in a given volume, but they are also right because of their nickel and cobalt. Delays in Production of Ultium modules Keeping these cells pushed the delivery of EV GM by 12 to 18 months, from the end of 2022 to the beginning of 2024 (Sales of GM EV increased constantly for three quarters, which suggests that troubles can be in the past).
In this maybe Ultium announced the second chemistry of the cell, which he calls “Mangan rich in litan” or LMR. He claims that LMR chemistry provides one-third of a higher energy density than the same volume of lithium iron phosphate cells (LFP)-the resourceable cost of cells-and reduces the costs of the highest EV and SUVs. These vehicles from Cadillac, Chevrolet and GMC employ giant battery packages from 109 to 205 kilowats.
The first LMR cells will leave the pilot line in 2027; The production of the full volume is expected to plan in 2028. In the Ultium plant it has not disclosed. In the case of Spring Hill, it now has LFP cell production, it seems that probably LMR cells come from other ultium cell plants in production – in Warren, Ohio.
Compact chemistry
The addition of lithium-spray-phosphate complements the GM Chemistries package will probably be used in EV from this year to the early 1930s. This applies to at least people produced outside China; Various models he builds in China have long included LFP chemistry, dominant chemistry in this country.
A significant part of intellectual property around Chemistries LFP is the property of Chinese companies, which caused trouble for Ford because it tries to add LFP cells to future EV models. GM spokesman told Wired that no intellectual property for LFP cells will be produced with the LG Energy Solution partner, is the property of every Chinese entity.
