1. A method of forming a coated lithium ion cathode material comprising:
in one pot;
forming a first solution comprising a digestible feedstock of a first metal suitable for formation of a cathode oxide precursor and a multi-carboxylic acid;
digesting said digestible feedstock to form a first metal salt in solution wherein said first metal salt precipitates as a salt of deprotonated said multi-carboxylic acid thereby forming an oxide precursor wherein said first metal salt comprises lithium and at least one of Mn, Ni, Co, Al or Fe;
adding a coating metal precursor salt after said digestion;
heating said oxide precursor to form said lithium ion cathode material with an oxide of said coating metal precursor salt as a coating on said lithium ion cathode material.
