▎ 摘　　要

NOVELTY - Preparing graphene composite conductive slurry comprises (1) sequentially acidifying the graphite and intercalating, washing, and drying to obtain expandable graphite, (2) performing a microwave expansion treatment on the expandable graphite) under the protection of an atmosphere to obtain expanded graphite, (3) mixing the expanded graphite with a solvent and a carbon black conductive agent, and subjecting the obtained mixture to a secondary microwave expansion treatment under atmosphere protection to obtain a pre-slurry, where the solvent is N-methylpyrrolidone, dimethylformamide, diethylformamide, dimethylsulfoxide, methanol, ethanol, ethylene glycol and/or tetrahydrofuran and (4) mixing the pre-slurry and glue solution and performing ultrasonic stirring to obtain a graphene composite conductive paste, where the glue liquid is a mixed liquid of polyvinylidene fluoride, polytetrafluoroethylene, carboxymethyl cellulose or styrene butadiene rubber and a solvent. USE - The method is useful for preparing graphene composite conductive slurry. ADVANTAGE - The graphene composite conductive paste has a complete sheet structure, good stability, and good electrical conductivity. DETAILED DESCRIPTION - AN INDEPENDENT CLAIM is also included for graphene composite conductive paste.
