As a result of testing by UC San Diego, I've confirmed the 4680 uses synthetic anode. The question is, what are the implications of that? To answer that question, today I’m going to walk you through the analysis done by UC San Diego, the differences between synthetic and natural graphite anodes, why Tesla may have chosen synthetic graphite, and what that choice could mean for Tesla’s supply chain.
