LFP is rumored to be part of Tesla battery investor day, where the LFP will be used for cheap / standard range cars at $80/kwhr at PACK level, and NMC for higher performance / longer range.

And allegedly LFP is improving density further based on some chinese rumors about CATL's advances in LFP for next year's batteries.

But there's so many rumors...

That is my guess. If you treat a LFP battery well you can probably get 4000 cycles out of it. If one cycle is 250 mi then there's your 1M.

Downsides are lower energy density and higher internal resistance, so it's probably not the battery they would want in one of those super fast Roadsters with the huge range.
