Abstract: The present invention is a simple and reliable method for producing lithiated metal oxides such as those useful as cathode materials in lithium ion electrochemical cells. The method is based on the use of an organic solvent that dissolves both lithium sulfide and elemental sulfur without dissolving the metal oxide or the lithiated product. Lithium sulfide and the metal oxide as a powder are refluxed in the organic solvent under an inert atmosphere. The organic solvent dissolves the lithium sulfide and the dissolved sulfide reduces the metal oxide allowing the intercalation of lithium. At the same time the sulfur that results from the oxidation-reduction reaction is carried away by the solvent thereby promoting the reaction and preventing contamination of the product with sulfur.

Abstract: In a new process for making a cathode current collector assembly, a cathode composition is positioned on a substrate between the substrate and a releasable layer. Next, force is applied on the releasable layer and directed toward the substrate so as to provide a smooth cathode surface in contact with the releasable layer. The cathode composition having the releasable layer maintained thereon is cooled to reduce the tackiness of the cathode composition and then the releasable layer is removed while the cathode composition remains in its condition of reduced tackiness. In an alternative process, the cathode composition is applied and then force is applied immediatly before or simultaneously with cooling the composition to a state of reduced tackiness. An electrolyte composition is applied to the smooth surface cathode and the cathode and electrolyte compositions are cured together. In a final step, an anode layer is applied onto the electrolyte composition to form a cell assembly and further curing may occur.
