In this video I'll do a deep dive in CATL's M3P chemistry, which is an LMFP chemistry with some additional dopants. LMFP increases the energy density of LFP by 15-20% by adding some additional manganese. The question is, if that's how simple it is, why didn't this happen before? In short, it's manganese demons like Jahn-Teller effects and dissolution issues.
