Patent ID: 11881580

Abstract:
A bipolar electrode for a lithium battery, the bipolar electrode comprising: (a) a current collector comprising a conductive material foil having two opposing primary surfaces, wherein one or both of the primary surfaces is optionally coated with a layer of graphene or expanded graphite material; and (b) a negative electrode layer and a positive electrode layer respectively deposited on the two primary surfaces, 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 nitrile and 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 a curing agent, and (iii) a lithium salt. Also provided is a bipolar battery that comprises a plurality of bipolar electrodes connected in series.
