Abstract: An improved dielectric layer of an electroluminescent laminate, and method of preparation are provided. The dielectric layer is formed as a thick layer from a ceramic material to provide:a dielectric strength greater than about 1.0.times.10.sup.6 V/m;a dielectric constant such that the ratio of the dielectric constant of the dielectric material to that of the phosphor layer is greater than about 50:1;a thickness such that the ratio of the thickness of the dielectric layer to that of the phosphor layer is in the range of about 20:1 to 500:1; anda surface adjacent the phosphor layer which is compatible with the phosphor layer and sufficiently smooth that the phosphor layer illuminates generally uniformly at a given excitation voltage.The invention also provides for electrical connection of an electroluminescent laminate to voltage driving circuity with through-hole technology. The invention also extends to laser scribing the transparent conductor lines of an electroluminescent laminate.

Abstract: An electrode apparatus is disclosed including an electrode which forms a porous, exterior, amalgamated deposit thereon; and means for applying a compressive load to the electrode such that the deposit, when formed, is compressed so as to enhance stripping from the outer surface of said amalgamated deposit. Also a battery, a method of making a battery and a method of operating a battery including such an electrode apparatus are also disclosed.

Abstract: A battery cell and a method for preparing a battery cell are disclosed in which a substantially fixed volume container includes the cell components therein in voltaic relationship, with the cell components including an anode comprising lithium metal, a non-aqueous electrolyte and a cathode in a spatial relationship to the anode within the fixed volume container, wherein the cathode comprises cathode active material which upon discharge intercalates lithium and undergoes a phase transition to a distinct structural phase in which phase the cathode active material can reversibly operate and which phase provides a cathode expansion greater than the anode volume decrease upon discharge, and wherein the spatial relationship and the cathode expansion within the substantially fixed volume are sufficient to produce a compressive load on the anode which inhibits the formation of a porous deposit of exterior, irregularly oriented, amalgamated lithium grains on the anode when the cell is reversibly operated with the cath

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

Abstract: 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.

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.

Abstract: 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.

Abstract: 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.
