Tesla will start using a so-called “M3P battery” with lithium manganese iron phosphate (LMFP)-based anodes from partner CATL for its Model Y crossovers in the fourth quarter of this year, Chinese media outlet LatePost reported Thursday, citing people familiar with the matter. LMFP is a variation on the LFP batteries which have been used in its standard-range electric vehicles at a relatively low cost to date, with the addition of manganese, and can offer longer ranges for the same weight. The Chinese battery giant has previously supplied Tesla with nickel-manganese-cobalt (NMC) batteries for the long-range version of the Model Y, those batteries are more costly and less thermally stable than LFP cells.
