117 “This is simply a large deal,” said Michigan politician Gretchen Whitmer successful a press conference unveiling plans for the factory. Expanding artillery options volition let Ford to “build much EVs faster, and yet marque them much affordable,” said Bill Ford, Ford’s enforcement chair.
Also known arsenic lithium ferrous phosphate (LFP) batteries, the benignant to beryllium produced astatine the caller works are a lower-cost alternate to the nickel- and cobalt-containing batteries utilized successful astir electrical vehicles successful the US and Europe today. While the exertion has grown successful popularity successful China, Ford’s factory, developed successful concern with the Chinese artillery elephantine CATL, marks a milestone successful the West. By cutting costs portion besides boosting charging velocity and extending lifetime, LFP batteries could assistance grow EV options for drivers.
Lithium-ion batteries each incorporate lithium, which helps store complaint successful a portion of the artillery called the cathode. But lithium doesn’t bash this occupation alone: it’s joined successful the cathode by a supporting formed of different materials.
The astir communal benignant of cathode utilized successful vehicles contiguous contains nickel, manganese, and cobalt successful summation to lithium. Some automakers, similar Tesla, usage different cathode chemistry made with nickel, cobalt, and aluminum. Both these cathode types person risen to prominence successful portion due to the fact that they person precocious vigor density, meaning the batteries volition beryllium smaller and lighter than others that tin store the aforesaid magnitude of energy.
While those 2 utilized to beryllium the default choices for cathodes successful EV batteries, lithium robust phosphate, an older chemistry, has seen a comeback successful the past fewer years, mostly driven by immense maturation successful China.
These iron-containing batteries thin to beryllium astir 20% cheaper than different lithium-ion batteries with the aforesaid capableness today. This is partially due to the fact that LFP doesn’t incorporate cobalt oregon nickel, costly metals that person seen immense terms swings successful caller years. Battery makers are besides moving to trim cobalt contented due to the fact that mining the metallic has been tied to peculiarly harmful moving conditions.
Making cathodes without cobalt and nickel could assistance automakers chopped costs, and immoderate person already begun to displacement artillery chemistry utilized successful vehicles sold successful the US. Tesla imports LFP cells from China contiguous for immoderate models, including its Model 3. Ford previously announced that it would commencement utilizing the exertion successful its Mach-E successful 2023 and successful the F-150 Lightning successful 2024.
With its recently announced factory, Ford would go the archetypal automaker to nutrient LFP batteries successful the US. The caller facility, which volition usage exertion from CATL, could assistance kick-start LFP accumulation successful the US much broadly. “It’s a pivotal constituent for the North American manufacturing landscape,” says Evelina Stoikou, a artillery exertion expert astatine BloombergNEF, an energy-focused probe firm.
Several smaller LFP accumulation facilities could besides travel online astir the aforesaid clip arsenic the Ford plant.
In October 2022, the US national authorities announced a astir $200 cardinal investment to assistance a institution called ICL-IP America physique a mill successful Missouri. The works volition marque worldly for LFP cathodes, which volition past beryllium utilized to marque batteries. It should statesman accumulation successful 2025.
Meanwhile, a Utah-based institution called American Battery Factory is planning a accumulation installation for LFP batteries successful Tucson, Arizona. That installation is expected to outgo astir $1.2 cardinal and should travel online successful 2026.
While the expanding availability of alternate artillery chemistries could importantly grow options for automakers and drivers, LFP astir apt won’t afloat regenerate different technologies. “It’s not the beatified grail for batteries,” Stoikou says.
LFP batteries are cheaper than different chemistries and tin person a longer lifetime, but they besides thin to beryllium heavier and bulkier. That tin beryllium a occupation for vehicles, due to the fact that if a artillery is heavier, it volition instrumentality much vigor to cart around, limiting range. And larger batteries could instrumentality up abstraction for seating oregon cargo.
Drivers successful the US and Europe thin to similar bigger vehicles with longer range. That makes it indispensable to battalion much vigor into a constrained space, truthful LFP mightiness ne'er predominate successful the West arsenic it has successful China, Stoikou says.
LFP maturation volition apt level disconnected aft this year, stabilizing astatine astir 40% of the planetary artillery marketplace for EVs, Stoikou says. And looking ahead, we’ll apt soon spot other, newer chemistries making their mode into cars.
Adding manganese to iron-containing batteries could boost efficiencies portion keeping costs low. Automakers could determination distant from lithium-ion chemistries altogether, alternatively shifting to solid-state lithium-metal batteries, which could person adjacent higher vigor density. And EVs mightiness not adjacent trust connected lithium successful the future, since sodium-ion batteries could connection a cheaper enactment down the road.
Each of those chemic combinations mightiness beryllium cardinal to proscription successful the future. It's LFP's infinitesimal now, but determination are plentifulness of others conscionable down it.
