Tesla secures five-year supply of lithium in deal with China’s Yahua

Mon, 01/04/2021 - 11:01 -- paul Crompton

US electric vehicle (EV) maker Tesla has signed a five-year deal to receive battery-grade lithium hydroxide from China’s Sichuan Yahua Industrial Group. 

The total value of the contract, signed by Yahua's wholly-owned subsidiary Yaan Lithium, is $630-$880 million and lasts up to 2025, according to news outlet Reuters, which quoted a filing by the Shenzhen Stock Exchange.

The cost value translated into a total lithium hydroxide procurement amount of 63,000-88,000 tonnes, or 12,600-17,600 tonnes per annum, according to analysts at Daiwa Capital Markets.

Last May, Yahua commissioned a 20,000 tonnes per year lithium hydroxide plant in Yaan city into operation, more than doubling its previous capacity.

It already sources lithium - an ingredient in EV batteries - from China’s Ganfeng Lithium, one of the world’s top lithium producers.

In 2018, Tesla signed a deal to receive a fifth of China's largest lithium compounds producer, Jiangxi Ganfeng Lithium’s production. Under the terms of the agreement, Tesla also designated its battery suppliers to buy lithium-hydroxide products from Ganfeng.

In 2019, Ganfeng Lithium finalised a $160 million investment deal to raise its stake in Argentina’s Cauchari-Olaroz lithium brine project to 50%. Ganfeng Lithium now partners with Canada’s Lithium Americas in a 50-50 joint venture that will develop and operate the project.

Battery materials manufacturer to idle portions of its US lithium production

Battery materials firm Albemarle is due to idle portions of its lithium mine and production facility in the US due to short-term supply-demand imbalances and an excess stockpile of battery-grade lithium.

The North Carolina-headquartered firm’s Silver Peak lithium mine in Nevada and Kings Mountain lithium hydroxide production facility in North Carolina are due to partially close next month until the end of the year.

Skoltech scientists use bespoke lithium-ion cell to view SEI formation

Fri, 06/12/2020 - 10:36 -- paul Crompton

Researchers from Russia’s Skoltech Center for Energy Science and Technology (CEST) have used a bespoke lithium-ion cell to visualise solid electrolyte interphrase (SEI) formation on battery-grade materials.

The specially designed cell allowed the measurements necessary for this direct observation of SEI formation on battery-grade carbonaceous electrode materials using in situ atomic force microscopy (AFM).
