Abstract: The composite electrolyte for use in a thin plate rechargeable lithium battery comprises a porous or microporous inert polymer separator laminate which carries another porous polymer containing a dissociable lithium compound, and the adherent polymer layers are impregnated with an organic liquid containing a lithium salt. The porous or microporous separator laminate may be a single polymer layer or a multiple polymer layer. The composite electrolyte is inserted between the electrodes of a rechargeable lithium battery. In another embodiment the porous polymer separator sheet has an adherent dissociable lithium compound containing polymer layer on each of its major faces.

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.

Abstract: A lithium battery constructed of lithium ion containing folded and stacked electrochemical cells is described, having a folded continuous, flexible lithium ion containing polymer laminate electrolyte sandwiched between first and second polarity lithium containing discrete electrode plates. The first and second polarity discrete electrode plates are carried, respectively, by first and second electrical current conducting flexible polymer laminates. The assembled polymer laminates are folded and stacked, connected to current collectors and packed into a lithium battery case.
