Abstract
A process for forming an active cathode material. The process comprises forming a precursor comprising a lithium salt and a multi-carboxylic acid salt of at least one of nickel, manganese or cobalt; heating the precursor in a metal lined vessel to a temperature of no more than 600° C. to form an intermediate material; and heating the intermediate material to a temperature of over 600° C. to form said active cathode material.
