▎ 摘  要

NOVELTY - A graphene conductive solution comprises 0.5-20 wt.% graphene, 0.1-5 wt.% dispersant, 0.1-5 wt.% stabilizer, 0.1-5 wt.% wetting agent and 70-99 wt.% solvent. The solvent is methyl pyrrolidone, dimethylformamide, dimethyl sulfoxide, dichloromethane, chloroform and/or tetrahydrofuran. USE - Graphene conductive solution is used in lithium ion battery, coating, aerospace, rubber, communication, electronics and energy applications (all claimed). ADVANTAGE - The graphene conductive solution has excellent storage stability, and is prepared by simple process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene conductive solution.
