Abstract
Provided is a positive electrode active material for a lithium-ion battery, the positive electrode active material including a blend of a doped lithium manganese iron phosphate (dLMFP) according to the formula: LiMnFeMPO, wherein 0.9<x+y<1; and M is one or more selected from the group consisting of Mg, Ca and Ba with one or both of a lithium nickel cobalt manganese oxide (NMC) compound having a Ni content greater than 0.6 relative to a total amount of metals other than Li and a lithium nickel cobalt aluminum oxide (NCA) compound. In particular, provided is a blend at a weight ratio of dLMFP to NMC and/or NCA (i.e., dLMFP:(NMC+NCA)) of >70:<30, such as 75:25, 80:20, 85:15, 90:10, etc.
