Fabrication of FePO4 layer coated LiNi1/3Co1/3Mn1/3O2: Towards high-performance cathode materials for lithium ion batteries

FePO4 coated LiNi1/3Co1/3Mn1/3O2 showed an improved cycle and rate capacities. The FePO4 coating layer significantly suppressed the increase of charge-transfer resistance (Rct) upon cycling and reduced the activation energy of the charge transfer processes. The surface of layered LiNi1/3Co1/3Mn1/3O2...
