A battery cathode comprising MoO.sub.2 or MoS.sub.2 particles coated with MoO.sub.2 and methods of making same are disclosed.

Battery cathode and method of making same

A battery comprising a lithium anode and a cathode, the cathode-active material of which comprises MoO.sub.2 or MoS.sub.2 particles coated with MoO.sub.2 is disclosed.

Battery

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.

Battery cathode and method

A battery having a layered transition metal dichalcogenide cathode in which has been incorporated by intercalation a relatively small amount of a dopant material having a relatively large atomic or ionic size so as to spread apart adjacent molecular layers in the cathode material and permit more rapid intercalation of cations during the battery discharge, an anode, and an electrolyte which will permit the migration of cations from the anode to the cathode. The preferred dopants are sodium or potassium and the invention is chiefly applicable to a battery having a molybdenum disulphide cathode.

Electrical storage device

A cathode material for use in lithium batteries which exhibits several distinct phases of operation. Cathode potential may be reversibly cycled in each phase. Phase changes occur at constant potential as concentration of lithium in the cathode material varies.
