Meet the brand new batteries unlocking cheaper electrical autos

“It is a massive deal,” mentioned Michigan governor Gretchen Whitmer in a press convention unveiling plans for the manufacturing facility. Increasing battery choices will permit Ford to “construct extra EVs quicker, and in the end make them extra inexpensive,” mentioned Invoice Ford, Ford’s govt chair. 

Also called lithium ferrous phosphate (LFP) batteries, the sort 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 at present. Whereas the know-how has grown in recognition in China, Ford’s manufacturing facility, developed in partnership with the Chinese language battery large CATL, marks a milestone within the West. By reducing prices whereas additionally boosting charging pace and lengthening lifetime, LFP batteries may assist increase 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 forged of different supplies.

The most typical type of cathode utilized in autos at present 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, that means the batteries will likely be smaller and lighter than others that may retailer the identical quantity of vitality.

Whereas these two was once the default selections for cathodes in EV batteries, lithium iron phosphate, an older chemistry, has seen a comeback prior to now few years, largely pushed by big development in China.

These iron-containing batteries are typically about 20% cheaper than different lithium-ion batteries with the identical capability at present. That is partly as a result of LFP doesn’t comprise cobalt or nickel, costly metals which have seen big worth swings in recent times. Battery makers are additionally working to scale back cobalt content material as a result of mining the metallic has been tied to significantly dangerous working circumstances. 

Making cathodes with out cobalt and nickel may assist automakers lower prices, and a few have already begun to shift battery chemistry utilized in autos offered within the US. Tesla imports LFP cells from China at present for some fashions, together with its Mannequin 3. Ford beforehand introduced that it will begin utilizing the know-how in its Mach-E in 2023 and within the F-150 Lightning in 2024. 

With its newly introduced manufacturing facility, Ford would turn out to be the primary automaker to provide LFP batteries within the US. The brand new facility, which can use know-how from CATL, may 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.
