LFP batteries use a lithium-ion-derived chemistry and share many of the advantages and disadvantages of other lithium-ion chemistries. However, there are significant differences. Iron and phosphates are very common in the Earth's crust. LFP contains neither nor, both of which are supply-constrained and expensive. As with lithium, human rights and environmental concerns have been raised concerning the use of cobalt. Environmental concerns have also been raised regardi.
