▎ 摘　　要

NOVELTY - The electrically conductive cathode or anode comprises particles of an electroactive material, a conductive graphene polymer binder (1-15 wt.%) that bonds particles of the electro-active material together, and a conductive filler (1-15 wt.%). The graphene polymer has a length or width of 100 nm to 1 mu m, an electrical conductivity of greater than 500 S/cm and/or a thermal conductivity of greater than 300 W/(mK) when measured in a thin film form with a thickness of less than 1 mu m, an oxygen content of less than 5-25 wt.%, and a chemical functional group. USE - The electrically conductive cathode or anode is useful for an electrochemical cell such as an alkali battery, alkaline battery, a metal-air battery, a supercapacitor, a lithium metal battery, a lithium-ion battery, or a lithium-air battery (all claimed). ADVANTAGE - The electrically conductive cathode or anode enhances reliability and lifespan of the battery, exhibits reduced electrical resistance during electrical charge and discharge of the battery, and has good structural integrity. DETAILED DESCRIPTION - The electrically conductive cathode or anode comprises particles of an electroactive material, a conductive graphene polymer binder (1-15 wt.%) that bonds particles of the electro-active material together, and a conductive filler (1-15 wt.%). The graphene polymer has a length or width of 100 nm to 1 mu m, an electrical conductivity of greater than 500 S/cm and/or a thermal conductivity of greater than 300 W/(mK) when measured in a thin film form with a thickness of less than 1 mu m, an oxygen content of less than 5-25 wt.%, and a chemical functional group attached to an edge or surface of the graphene polymer. The cathode or anode has an electrical conductivity of greater than 1 S/cm when measured in a dry cathode or anode state without electrolyte. The cathode or anode is produced by preparing a precursor solution or suspension, where the graphene polymer is dissolved or dispersed in a liquid medium, mixing particles of the electro-active material in the precursor solution or suspension to form a slurry or paste, applying a coating of the slurry or paste onto a current collector, and removing the liquid medium from the coating to form the cathode or anode. INDEPENDENT CLAIMS are included for: (1) a precursor solution or suspension; (2) a binder solution or suspension; (3) a precursor paste; and (4) a process for producing cathode or anode. DESCRIPTION OF DRAWING(S) - The diagram shows a graphical view of an electrical conductivity of dry cathode or anode.
