Lithium phosphate (Li 3 PO 4 ) is a well-known solid electrolyte for lithium-ions. In this study, we analyzed the effects of Li 3 PO 4 coating on the electrochemical performance of LiNi 0.6 Co 0.2 Mn 0.2 O 2 (NCM), a nickel-rich cathode. In particular, the coated materials exhibited enhanced cycle s...
