▎ 摘　　要

NOVELTY - The method involves dispersing graphene i.e. commercial graphene slurry, into water. Stirring process is performed to obtain graphene mixture. Vibration i.e. ultrasonic vibration, filtering and freeze-drying operations are performed on the graphene mixture to obtain a graphene thin film. Rolling process on the graphene thin film. Annealing process is performed under protection of argon gas. A graphene anode pole piece is obtained after completing cooling process, where freeze-drying temperature is about minus 70 degrees centigrade to minus 50 degrees centigrade and freeze-drying time is about 24h to 60h. USE - Method for preparing a Graphene anode pole piece of an aluminum-graphene battery (all claimed). ADVANTAGE - The method enables achieving high grain orientation of the Graphene anode pole piece, reducing defects of the Graphene anode pole piece, and improving performance of an aluminum-graphene battery, realizing constant current charging and discharging of the aluminum-graphene battery at 100A/g, and maintaining capacity of the aluminum-graphene battery at 0.10Ah/g. DESCRIPTION OF DRAWING(S) - The drawing shows a photograph view of a Graphene anode pole piece.
