An electro-active compound particulate coated with a conducting polymer composition finds use in electrochemical cell electrodes.

Conductive-polymer-coated electrode particles

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.

Method for preparing lithiated metal oxides

A metal ion intercalation compound suitable for use as the cathode material in an alkali metal battery. In one embodiment, a metal ion intercalation compound is mixed with an electrically conductive material. The metal ion intercalation compound is represented by the formula:

The subject invention provides a three-step process for electrolyte deposition. A surplus of electrolyte pre-wet material, having a relatively low viscosity, is layered onto a dry, porous electrode. Surplus pre-wet material is mechanically removed from the surface of the electrode. This also removes bubbles or foaminess which has developed in the pre-wet material. The pre-wet solution is allowed to absorb into the porous electrode, and the surface is then coated with the high-viscosity electrolyte precursor. Curing or further processing of the electrode/electrolyte then continues with standard processes.
