Official Chinese figures confirmed that batteries utilizing lithium iron phosphate or LFP expertise accounted for 57% of whole battery manufacturing for autos in China throughout 2021, up from lower than half the earlier yr.
The LFP batteries have stormed into the lead in China as a result of they use comparatively cheap iron in the battery’s cathode in place of costlier metals resembling nickel.
Their rise has coincided with the emergence of electric vehicles as a mass-market product in China. In 2021, new-energy autos, a class that principally consists of EVs, accounted for almost one in six passenger cars sold in China, the world’s high auto market by variety of autos bought.
As Chinese automotive sellers promote extra EVs and a larger proportion of these EVs carry LFP batteries, manufacturing of the iron batteries is surging. In 2021, Chinese battery makers produced LFP batteries with 125.4 gigawatt-hours of capability, greater than triple the determine from a yr earlier, mentioned the government-backed China Automotive Battery Research Institute.
U.S. and European automotive firms historically frowned on LFP batteries as a result of they have an inclination to have decrease power density than nickel-based batteries, which means the automobiles they energy can’t journey as far on a single cost. LFP batteries are also extra possible to undergo from poor efficiency in chilly climate.
Over the final 20 years, Chinese firms attempting to meet up with Japan and the U.S. in battery expertise centered on bettering LFP expertise, not solely due to the associated fee but additionally as a result of the batteries are much less possible to catch hearth. A change in Chinese authorities EV subsidies, which beforehand favored longer-range automobiles, additionally helped the expertise acquire an edge.
One of the strongest advocates is Tesla’s Mr. Musk, who has mentioned that discovering sufficient nickel at affordable price is a significant manufacturing concern. He has pushed again in opposition to the concept that clients shopping for an LFP automotive are getting a second-class product.
“Our intent with this pack is that product expertise is roughly equal between nickel & iron,” Mr. Musk wrote on Twitter last August to a buyer who was provided earlier supply of a Tesla if he selected the LFP possibility.
“I’d personally barely go for iron pack, because it desires to be charged to 100% whereas nickel prefers ~90%,” Mr. Musk mentioned in the Twitter publish.
Car makers in the U.S., Europe and Japan are all stepping up battery manufacturing and plenty of are engaged on LFP expertise, however they typically haven’t gotten so far as Tesla and Chinese makers in bringing the expertise into mass-market manufacturing.
Tesla first used LFP batteries for its China-made Model 3 in 2020. Last October, the corporate mentioned it will prolong using the iron-based batteries to all of its standard-range automobiles. China’s Contemporary Amperex Technology Co., the world’s greatest maker of electric-vehicle batteries, provides Tesla with LFP batteries.
Other Chinese electrical car manufacturers are additionally turning into heavy customers of LFP cathodes. The Hong Guang Mini, a tiny hatchback costing as little as $4,400, was China’s bestselling EV in 2021. It is made by a three way partnership of
General Motors Co.
and two different Chinese firms.
Ltd., a Chinese firm that makes each electrical autos and the batteries that go into them, has designed an LFP battery in a blade form. It says its design has greater power density to give EVs longer vary.
“Almost all of the automotive manufacturers you may consider are in talks with us about cooperation based mostly on blade battery applied sciences,” BYD’s Vice President He Long mentioned final yr when asserting the battery, in accordance to the corporate’s social-media account.
