Claim 28:
29. A method of producing the bipolar electrode of claim 1, the method comprising:
a. providing the current collector comprising a conductive material foil having a thickness from 10 nm to 100 μm and two opposing primary surfaces;
b. depositing a reactive cathode layer onto a first primary surface of a current collector to form a reactive cathode layer-coated current collector, wherein the reactive cathode layer comprises a mixture of multiple particles of the cathode active material, a conductive additive, a nitrile, and a reactive liquid electrolyte composition comprising at least a polymerizable first liquid solvent, a lithium salt dissolved in the first liquid solvent, and a crosslinking agent and/or an initiator, wherein the first liquid solvent occupies from 1% to 99% by weight based on the total weight of the reactive liquid electrolyte composition; and
c. partially or totally polymerizing the first liquid solvent to obtain a cathode active layer-coated current collector wherein from 30% to 100% by weight of the polymerizable first liquid solvent is polymerized to become a quasi-solid or solid-state electrolyte that chemically bonds the multiple particles of the cathode active material and the conductive additive together to form a cathode active layer that adheres to the first primary surface.
