Most Chinese-built EVs use LFP. And China is the world's largest EV market, bigger than the rest of the world combined. So presumably, the majority of EVs shipping globally are using LFP batteries today.
Absolutely. Likewise most of the battery-electric buses in London (and presumably, other European cities) have always used LFP. Safety is a big consideration there as nobody wants a bus-sized battery fire in the middle of a dense city.
