Abstract
A method for producing electrodes for use in secondary cells. A suspension in oil of fine particles of electrode material is applied as a film to a metal foil substrate which is then baked in an inert atmosphere at temperatures high enough to drive off the oil yet below the melting point of the metal foil substrate. Oxygen is introduced to the baking atmosphere at selected times to slightly oxidize or carbonize the electrode material. The preferred electrode material is molybdenum disulphide and the invention is chiefly applicable to the fabrication of molybdenum disulphide battery cathodes on aluminum foil.
