“This can be a massive deal,” stated Michigan governor Gretchen Whitmer in a press convention unveiling plans for the manufacturing unit. Increasing battery choices will permit Ford to “construct extra EVs quicker, and finally make them extra inexpensive,” stated Invoice Ford, Ford’s government chair. Also called lithium ferrous phosphate (LFP) batteries, the kind to be produced on the new plant are a lower-cost different to the nickel- and cobalt-containing batteries utilized in most electrical autos within the US and Europe right this moment. Whereas the know-how has grown in recognition in China, Ford’s manufacturing unit, developed in partnership with the Chinese language battery large CATL, marks a milestone within the West. By chopping prices whereas additionally boosting charging velocity and lengthening lifetime, LFP batteries might assist develop EV choices for drivers.
Lithium-ion batteries all comprise lithium, which helps retailer cost in part of the battery referred to as the cathode. However lithium doesn’t do that job alone: it’s joined within the cathode by a supporting solid of different supplies. The commonest sort of cathode utilized in autos right this moment comprises nickel, manganese, and cobalt along with lithium. Some automakers, like Tesla, use one other cathode chemistry made with nickel, cobalt, and aluminum. Each these cathode sorts have risen to prominence partially as a result of they’ve excessive vitality density, which means the batteries will likely be smaller and lighter than others that may retailer the identical quantity of vitality.
Whereas these two was the default decisions for cathodes in EV batteries, lithium iron phosphate, an older chemistry, has seen a comeback previously few years, largely pushed by large development in China. These iron-containing batteries are typically about 20% cheaper than different lithium-ion batteries with the identical capability right this moment. That is partly as a result of LFP doesn’t comprise cobalt or nickel, costly metals which have seen large value swings in recent times. Battery makers are additionally working to cut back cobalt content material as a result of mining the metallic has been tied to notably dangerous working circumstances. Making cathodes with out cobalt and nickel might assist automakers reduce prices, and a few have already begun to shift battery chemistry utilized in autos offered within the US. Tesla imports LFP cells from China right this moment for some fashions, together with its Mannequin 3. Ford beforehand introduced that it could begin utilizing the know-how in its Mach-E in 2023 and within the F-150 Lightning in 2024. With its newly introduced manufacturing unit, Ford would turn out to be the primary automaker to supply LFP batteries within the US. The brand new facility, which is able to use know-how from CATL, might assist kick-start LFP manufacturing within the US extra broadly. “It’s a pivotal level for the North American manufacturing panorama,” says Evelina Stoikou, a battery know-how analyst at BloombergNEF, an energy-focused analysis agency.
