ABSTRACT:
The non-aqueous thin film rechargeable lithium battery described has a negative electrode comprising a polymer laminate having embedded therein carbon, and a layer of fine carbon agglomerated with a lithium compound containing organic binder carried by the polymer laminate. The positive electrode of the rechargeable lithium battery contains a layer of fine particles of vanadium oxide, manganese oxide, cobalt oxide, nickel oxide or silver vanadate, agglomerated with a lithium compound containing organic binder and the layer is supported on another polymer laminate embedding carbon. In one embodiment the lithium battery has a solid polymer electrolyte containing a lithium compound capable of releasing lithium ions, located between the positive and negative electrodes. In another embodiment a microporous polymer laminate separator which has been impregnated with an organic liquid electrolyte containing a lithium compound, is placed between the polymer laminate negative electrode and the polymer laminate positive electrode. In both embodiments the electrodes are rendered adherent to the mobile lithium ion carrying electrolyte with a coating of an organic adhesive containing a lithium compound in a concentration lower than in the electrolyte, disposed between them.
