The automaker says that it had directly sourced over 95% of the lithium hydroxide, 50% of the cobalt, and more than 30% of the nickel used in its high-energy density cells (NCA and NCM) in 2021. Tesla even released some very rare and interesting details about the effort. It also enables more transparent and traceable supply chains and better environmental and social data. Direct sourcing from mining companies allows Tesla to engage directly in local contexts instead of having to rely on multiple midstream companies that typically sit between EV makers and mining. While cobalt, nickel, and lithium go through multiple processing steps by different companies, some of the more important environmental and social risks in this supply chain are present at mine sites. Tesla explained in its latest Impact Report: This approach enables Tesla to have direct relationships with miners of critical minerals and helps secure supply while allowing the company to monitor quality closely and ensure responsible environmental and social sourcing. While Tesla sources the vast majority of its battery cells from suppliers, it actually sources a large part of the materials used to build those batteries directly from mines. This approach is going to be critical as companies fight to secure those minerals for battery production to support electric vehicle growth. Tesla released interesting and rare details about its approach to sourcing lithium, nickel, and cobalt directly from mines instead of through its cell suppliers.
