Claim 0:
1. A bipolar electrode for a lithium battery, wherein said bipolar electrode comprises:
a) a current collector comprising a conductive material foil having a thickness from 10 nm to 100 μm and two opposing primary surfaces; and
b) a negative electrode layer and a positive electrode layer respectively deposited on the two opposing primary surfaces, each in contact with a primary surface of said conductive material foil, wherein the positive electrode layer comprises a mixture of particles of a cathode active material and a quasi-solid or solid-state electrolyte and the electrolyte comprises a mixture of a nitrile and a polymer, wherein the polymer 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, 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, phosphoric acids, phosphorous acid, phosphites, phosphoric acids, phosphazene compounds, derivatives thereof, and combinations thereof.
