Abstract: The invention relates to the technical field of lithium battery slurry materials, in particular to a conductive carbon material dispersing agent which comprises one of modified polyvinyl alcohol, alkyl ammonium salt copolymer, olefin block maleic anhydride copolymer and pyrrolidone copolymer, or mixtures thereof, and can effectively disperse carbon nanotube, graphene and other conductive carbon materials in a solvent to obtain uniform conductive slurry; further disclosed is a high-conductivity slurry for the lithium battery, which comprises 0.5-15.0% by weight of a conductive carbon material and 0.1-3.0% by weight of a dispersing agent, and can remarkably reduce the bulk resistivity of a positive electrode system of the lithium battery and improve the conductivity of a pole piece.
