You responded to a comment about cobalt with vague references to cell chemistry, cycle count, and energy density.

What does any of that have to do with cobalt?

The post you're replying to didn't explain it well, but: LFP batteries don't use cobalt (or nickel).

LFP production is starting to pass NMC (lithium + nickel manganese cobalt oxide). Slightly lower density but a lot of advantages in lack of easily catching on fire, longer lifetime -- and lack of cobalt. LFP (LiFePo4) is the battery chemistry of choice today for solar installations, where the longer lifetime and increased safety are a big win and the slightly lower density doesn't matter, unlike mobile applications.
