▎ 摘  要

NOVELTY - A graphene-containing conductive liquid preparing method involves centrifugally separating raw material graphene oxide, taking upper layer liquid, drying at a low temperature to obtain a graphene oxide powder having a small number of layers. The graphene oxide powder having a small number of layers is vacuum-dried to form a crude product. The crude product is mixed with an additive, dissolved in a heated organic phase, stirred uniformly, filtered while hot and dried the filtrate under vacuum to obtain a finished product Q. The finished product Q is configured to obtain the finished product, where the graphene-containing conductive liquid is composed of 1-25 wt.% finished product Q, 0.1-3 wt.% dispersing agent, 5-10 wt.% stabilizer and remaining solvent balance and the additive is diiodooctane or chloronaphthalene. USE - Method for preparing graphene-containing conductive liquid. ADVANTAGE - The method enables preparing graphene-containing conductive liquid with improved battery performance.
