▎ 摘　　要

NOVELTY - Graphene slurry comprises graphene, modified polyvinyl alcohol and foaming agent. The modified polyvinyl alcohol is modified with aromatic groups and amino groups. The foaming agent comprises ammonium sulfate or ammonium phosphate. USE - The graphene slurry is useful in battery (claimed). ADVANTAGE - The graphene slurry overcomes the ππ interaction and van der Waals force between graphenes, avoids the agglomeration of graphene, and obtains the graphene slurry with good dispersion stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of graphene slurry.
