Claim 43:
44. A method of producing a bipolar electrode, the method comprising:
A) mixing particles of a cathode active material, a conductive additive, a nitrile, and a reactive liquid electrolyte to form a reactive cathode layer and depositing the reactive cathode layer to a primary surface of a current collector, wherein the reactive liquid electrolyte comprises (i) a first liquid solvent that is polymerizable, (ii) an initiator and/or curing agent, and (iii) a lithium salt dissolved in the first liquid solvent, wherein the cathode active material occupies from 35% to 95% by weight based on the total weight of the reactive cathode layer;
B) mixing particles of an anode active material, a conductive additive, and a reactive liquid electrolyte to form a reactive anode layer and depositing the reactive anode layer to a second primary surface of the current collector, wherein a reactive additive comprises (i) a third liquid solvent that is polymerizable, (ii) an initiator and/or curing agent, and (iii) a lithium salt dissolved in the third liquid solvent, wherein the anode active material occupies from 35% to 95% by weight based on the total weight of the reactive anode layer; and
C) partially or totally polymerizing the first solvent and the third solvent to obtain the 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.
