Claim 39:
40. A bipolar lithium metal battery comprising at least two bipolar electrodes, wherein at least one of the bipolar electrodes comprises (A) a current collector comprising a conductive material foil having two opposing primary surfaces; (B) a positive electrode layer deposited on one of the two primary surfaces, wherein the positive electrode layer comprises a mixture of particles of a cathode active material, a nitrile, and a quasi-solid or solid-state electrolyte and the electrolyte comprises a polymer, which is a polymerization or crosslinking product of a reactive additive comprising (i) a first liquid solvent that is polymerizable, (ii) an initiator or curing agent, and (iii) a lithium salt, wherein the first liquid solvent occupies from 1% to 99% by weight of the total weight of the reactive additive; and (C) initially no lithium metal deposited on the other of the two primary surfaces which constitutes a negative electrode layer; wherein the at least two bipolar electrodes are connected in series in such a manner that an ion-permeable separator is disposed between the negative electrode layer of the one of the bipolar electrodes and the positive electrode layer of a neighboring bipolar electrode, wherein the nitrile is selected from succinonitrile (SN), glutaronitrile (GLN), butyronitrile (BN), adiponitrile (ADN), acrylonitrile (AN), a derivative thereof, or a combination thereof, and the first liquid solvent is selected from the group consisting of vinylene carbonate, fluoroethylene carbonate, vinyl sulfite, vinyl ethylene sulfite, vinyl ethylene carbonate, 1,3-propyl sultone, 1,3,5-trioxane (TXE), 1,3-acrylic-sultones, methyl ethylene sulfone, methyl vinyl sulfone, ethyl vinyl sulfone, methyl methacrylate, vinyl acetate, acrylamide, 1,3-dioxolane (DOL), fluorinated ethers, fluorinated esters, sulfones, sulfides, dinitriles, acrylonitrile (AN), sulfates, siloxanes, silanes, N-methylacetamide, acrylates, ethylene glycols, phosphates, phosphonates, phosphinates, phosphines, phosphine oxides, phosphonic acids, phosphorous acid, phosphites, phosphoric acids, phosphazene compounds, derivatives thereof, and combinations thereof.
