Construction of Li3PO4 nanoshells for the improved electrochemical performance of a Ni-rich cathode material

Abstract

A Li₃PO₄ nanocoating around a nickel-rich cathode material was successfully constructed via controlling the reaction between the electrode material and a preformed phosphorus-containing polymeric nanoshell; this not only effectively tackles the alkali residue challenge, but it also contributes to much-improved electrochemical performance being shown by a high-energy cathode.
