What Tesla’s bet on iron-based batteries means for manufacturers – TechCrunch

Elon Musk earlier this week made his most bullish statements but on iron-based batteries, noting that Tesla is making a “long-term shift” towards older, cheaper lithium-iron-phosphate (LFP) cells in its power storage merchandise and a few entry-level EVs.

The Tesla CEO mused that the corporate’s batteries could ultimately be roughly two-thirds iron-based and one-third nickel-based throughout its merchandise. “And this is actually good because there’s plenty of iron in the world,” he added.

Musk’s feedback mirror a change that’s already underway inside the automotive sector, primarily in China. Battery chemistries exterior of China have been predominantly nickel-based — particularly nickel-manganese-cobalt (NMC) and nickel-cobalt-aluminum (NCA). These newer chemistries have change into engaging to automakers attributable to their increased power density, letting authentic gear manufacturers (OEMs) enhance the vary of their batteries.

If Musk’s bullishness is heralding a real shift throughout the EV business, the query is whether or not battery makers exterior of China will be capable of sustain.

Musk shouldn’t be the one automotive govt to sign a return to the LFP components. Earlier this yr, Ford CEO Jim Farley stated the corporate would use LFP batteries in some business autos. Meanwhile, Volkswagen CEO Herbert Diess introduced through the firm’s inaugural battery day presentation that LFP could be utilized in some VW entry-level EVs.

On the power storage entrance, Musk’s feedback about utilizing LFP-based chemistries in Powerwall and Megapack are in step with different stationary power storage firms pushing for iron-based formulation. “The stationary storage industry wants to move to LFP because it’s cheaper,” Sam Jaffe, who heads the battery analysis agency Cairn Energy Research Advisors, instructed TechCrunch.

LFP battery cells are engaging for a couple of completely different causes. For one, they’re not dependent on ultra-scarce and price-volatile uncooked supplies like cobalt and nickel. (Cobalt, which is predominantly sourced from the Democratic Republic of Congo, has undergone extra scrutiny attributable to inhumane mining situations.) And whereas they’re much less energy-dense than nickel-based chemistries, LFP batteries are less expensive. This is nice information for these trying to spur the shift to electrical autos as a result of reducing the associated fee per car will probably be key to better EV adoption.

Musk clearly sees a serious future for iron-based chemistries at Tesla, and his feedback have helped thrust LFP again into the highlight. But there’s one place the place they’ve remained the star of the present: China.

China’s monopoly on LFP

“LFP is pretty much only produced in China,” Caspar Rawles, head of worth and knowledge assessments on the analysis agency Benchmark Mineral Intelligence, defined in a current interview with TechCrunch.

China’s dominance in LFP battery manufacturing partially pertains to a collection of key LFP patents, that are managed by a consortium of universities and analysis establishments. This consortium got here to an settlement with Chinese battery makers a decade in the past underneath which the manufacturers wouldn’t be charged a licensing charge offering that the LFP batteries have been used solely in Chinese markets.

Hence, China cornered the LFP market.

Battery makers in China could profit most from a possible tectonic shift towards LFP — particularly BYD and CATL, the latter of which already manufactures LFP batteries for Tesla autos constructed and offered in China. (Volkswagen, in the meantime, has a considerable stake in Chinese LFP maker Gotion High-Tech.) These battery makers aren’t slowing down: In January, CATL and Shenzhen Dynanonic signed an settlement with a neighborhood Chinese province to construct an LFP cathode plant at a value of $280 million over three years.

The LFP patents are attributable to expire in 2022, business analyst Roskill explains, which may give battery manufacturers exterior China time to start out shifting a few of their manufacturing towards iron-based formulation. However, the entire deliberate battery factories in Europe and North America, lots of that are joint ventures with South Korean business giants like LG Chem or SK Innovation, are nonetheless targeted on nickel-based chemistries.

“For the U.S. to take advantage of LFP’s strengths, North American manufacturing will be necessary,” Jaffe defined. “Everyone building a gigafactory in the U.S. today is planning on making high nickel chemistries. There’s an enormous unmet need for locally manufactured LFP batteries.”

Rawles stated he expects some LFP capability in North America and Europe within the coming years, notably after the patents expire. He identified that each CATL and SVOLT, one other battery maker, have been making strikes in Germany — however each of those firms are Chinese, which leaves open the query of whether or not different Asian or Western firms can compete within the LFP market. (Stellantis selected SVOLT as one in every of its battery suppliers from 2025 onwards.)

On the power storage entrance, Jaffe stated he thinks “it’s inevitable that most stationary storage systems will eventually be LFP.”

However, not all is misplaced for home manufacturing within the United States. “The good news for building local LFP manufacturing is that the supply chain is simple: Outside of lithium, it’s iron and phosphoric acid, two cheap materials already made [in the U.S.] in large quantities,” Jaffe added.

In the tip, it’s not a query of 1 battery chemistry versus one other. What’s extra probably is what we’ve already began to see from automakers, together with Tesla: Iron-based batteries can be used predominately in entry-level and cheaper autos, whereas nickel-based cells can be used for higher-end and efficiency automobiles. Many customers will probably be content material with a 200- to 250-mile-range car that’s 1000’s of {dollars} cheaper than one with a spread of 300 to 350 miles.

Automakers have additionally begun making strikes to take management of the battery provide, whether or not by vertical manufacturing or joint ventures with established battery firms. That means that rising LFP capability in North America and Europe shouldn’t be solely probably, however inevitable.
