Lithium iron phosphate are not widely used in EVs. They gave poorer energy density, so lithium ion is preferred. I think electric golf carts use LiFePo batteries, to keep costs low and because range is less of an issue.
- rootusrootus 4y agoThe vast majority of EVs in China use LFP, and China has most of the EVs in the world. And even in the US, by volume I wouldn't be surprised if the RWD Model 3 is a reasonable fraction of total EV sales.
- bryanlarsen 4y agoMost EV's in China use LiFePO4 batteries, and China is the largest EV market.
- tuatoru 4y agoLFP batteries have not been widely used outside China till now because CATL[1] owns the important patents. The patents expire this year. The energy density discrepancy is not as bad at a system (whole vehicle) level as it appears at cell level, for various reasons. And there are lots of use cases where LFP has more than enough energy, provided the price is right. 1. https://en.wikipedia.org/wiki/CATL https://en.wikipedia.org/wiki/CATL
- SigmundA 4y agoThe energy density is partially offset by the higher cycle life of LFP even while charging to 100% SOC. For instance Tesla recommends an 80% charge for daily unless you know you are going to go a long trip, while on their LFP version they recommend a 100% daily charge to keep cell balance as the LFP pack will have a much longer life than a NCM pack at 80%. https://www.tesla.com/ownersmanual/model3/en_jo/GUID-7FE78D73-0A17-47C4-B21B-54F641FFAEF4.html https://www.tesla.com/ownersmanual/model3/en_jo/GUID-7FE78D7... LFP are ideal for shorter range commuter/daily driver cars and LFP tech seems to be closing the gap with cobalt energy density.
