Electric vehicles often differ based on different battery technologies. America’s electric automaker Tesla has set the trend for years. According to Yang Jie in the Wall Street Journal, “a less-expensive battery technology championed by Tesla” Inc. Of Elon Musk dominated the world’s largest auto market last year.”
Batteries are Lithium Iron Phosphate – often called LFP batteries. The WSJ’s G reports, “One of the strongest advocates is Tesla’s Mr. Musk, who has said that getting enough nickel at a reasonable cost is a major production concern.”
“Our intention with this pack is that the product feel is almost on par between Nickel and Iron,” Mr. Musco wrote on twitter last august To a customer who was offered first delivery of Tesla if he had opted for the LFP option.
“I personally would opt for the iron pack a bit, as it wants to charge to 100% while nickel prefers ~90%,” Mr Musk said in a Twitter post.
“Tesla first used LFP batteries for its China-made Model 3 in 2020. Last October, the company said it would expand the use of iron-based batteries to all of its Standard-class cars. The contemporary Amperex Technology Company, the world’s largest manufacturer of electric-vehicle batteries, supplies LFP batteries to Tesla,” notes the WSJ.
Meanwhile, “other Chinese electric vehicle brands are also becoming heavy users of LFP.” In fact, China’s EV brands have wholeheartedly adopted LFP, “not only because of the cost, but also because the batteries are less prone to fire,” according to the WSJ, translating into a better safety profile. In turn, the adoption of LFP in China has accelerated.
Numbers tell the story. “Batteries using lithium iron phosphate, or LFP technology, accounted for 57% of total battery production for vehicles in China during 2021, less than half of the previous year. LFP batteries have moved into the lead in China because They use relatively cheap iron. The cathode of the battery in place of expensive metals such as nickel,” reports G.
Although Tesla’s move to LFP batteries has caught up with China’s EV brands, traditional automakers (in Europe in the US) have been left behind. It has been reported that, “they have generally not progressed as far as Tesla and the Chinese manufacturers in bringing the technology into mass-market production.”
