What's wrong with this?

"If all Li-ion were replaced with LiFePO4 ebike fires would cease."

Figures here suggest that the space for a 500Wh Li-ion battery would hold about 450Wh of LiFePO4.

LFP batteries don't explode but still burn. This is because they don't produce oxygen when entering thermal runaway.

That sounds like a potential gain - if LFP fires don't develop as fast (through needing air) that would be some improvement.

I don't know if they're right but a couple of places say LFP don't catch fire on impact/puncture or shorting. I didn't find anything about other causes nor about LFP ebike fires, only that LFP batteries are used on a few cargo bikes.
