▎ 摘　　要

NOVELTY - Conductive carbon material dispersion liquid comprises conductive carbon material, conductive carbon material dispersant and solvent. The conductive carbon material dispersant is phenyl organic substance. The phenyl organic compound has lipophilic end alkyl chain, pyrrolyl group and hydrophilic group on the side chain of the benzene ring, and pyrrolyl group has an organic functional salt ion group. USE - The conductive carbon material dispersion liquid is useful as raw material of conductive binder including matrix composed of water-soluble polymer and water-soluble cellulose ether, polyvinyl alcohol, polystyrene sulfonic acid and/or polyethylene glycol, cross-linking agent composed of sodium polyacrylate, lithium polyacrylate, ammonium polyacrylate, sodium carboxymethyl cellulose, lithium carboxymethyl cellulose, ammonium carboxymethyl cellulose, sodium alginate and ammonium alginate, conductive carbon material dispersion and water-soluble solvent for lithium batteries (claimed). ADVANTAGE - The conductive carbon material dispersion liquid: concentrates hydrophilic groups, ionic hydrophilic groups, conductive organics and functional salts on the ring, which can improve the binding force with conductive carbon materials; has uniform and stable dispersion. The conductive binder of the lithium battery can maintain the stable conductive performance of the binder. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing conductive carbon material dispersion liquid, comprising (1) adding conductive carbon material dispersant into solvent, heating it in a water bath at 40-60degrees Celsius for 5-25 minutes, stirring until all the conductive carbon materials are dissolved to obtain dispersant solution, and cooling the dispersant solution to room temperature, (2) adding conductive carbon material into the dispersant solution in step (1) to form a mixed solution, placing the mixed solution in a water bath, maintaining the temperature of the water bath at room temperature, and carrying out ultrasonic treatment for 5-25 minutes under the conditions of the water bath, mechanically stirring the mixed solution intermittently in a water bath until the conductive carbon material is completely dissolved to obtain conductive carbon material dispersion.
