Abstract
A method is disclosed for increasing the reversible capacity of lithium transition metal oxide materials for use as cathodes in non-aqueous lithium batteries. The method involves reduction of oxide materials of the form Li.sub.x M.sub.y O.sub.z, wherein M represents transition metals whereby oxygen is removed while still maintaining the original phase of the material. Use of the method of the invention is particularly useful for oxide materials synthesized at low temperatures and where M is Mn.
