Reuters is reporting that Tesla is partnering with Chinese battery supplier CATL, to build Lithium Iron Phosphate (LFP), Cobalt-free, Prismatic battery cells for the Made In China Model 3. WHAT!? This is huge/totally unexpected news about Tesla's battery supply chains, and brings up far more questions than answers. Why is Tesla using less energy dense cells? Are they that much cheaper? Is Maxwell's DBE tech involved?!
