Modification of the surface of the Ni-rich material Li[Ni0.6Co0.2Mn0.2]O2 by H3PO4 induces the formation of a Li3PO4 nanolayer by reaction with residual LiOH and Li2CO3 on the surface, so that the amounts of residual lithium compounds are significantly reduced, and this solves the problem considered as one of the main causes of degradation during electrochemical cycling. In addition, the formed Li3PO4 surface layer has multi-functions such as absorption of water in the electrolyte that lowers the HF level, HF scavenging, and protection of the active materials from deleterious side reactions with the electrolyte.
