“One advantage of LFP batteries is that they don’t use cobalt, which is an expensive and sometimes controversial mineral.

Tesla has talked about phasing out cobalt in its batteries in the past, and its NCA battery cells already use less cobalt than most other cells of similar chemistry.

The main disadvantage of LFP batteries is their lower-energy density, but CATL, which is believed to be Tesla’s supplier, has made improvements in LFP energy density and longevity.”
