Abstract: A method of producing a particulate lithium metal oxide or lithium metal phosphate material comprising the steps of providing one or more metal compounds, adding sufficient water to dissolve the one or more metal compounds to form a metal compound solution, adding a first basic solution, a second basic solution and the metal compound solution at predetermined rates to a reaction vessel containing water to form a reaction mixture, heating the reaction mixture while maintaining a pH of the reaction mixture in a predetermined pH range, adding a lithium compound, adding a fatty acid, filtering a precipitate, washing and preferably drying the precipitate, calcining the dried precipitate in an atmosphere containing oxygen to form a calcined lithium metal oxide or lithium metal phosphate, cooling and sizing the calcined lithium metal oxide or lithium metal phosphate to produce a particulate lithium metal oxide or lithium metal phosphate material having a predetermined average particle size.
