▎ 摘  要

NOVELTY - The method involves adding graphite into graphene by mechanical shearing peeling machine (1) under dry condition. The graphene solution is prepared and re-dispersible glue powder precursor emulsion dispersion is added. The graphene solution is transmitted into spray drying tower (3). The graphene solution is dried with hot air. The redispersible rubber powder precursor emulsion is covered on graphene surface to forms a layer of glue and aggregated into powder of 5-10 microns, and then collected to obtain highly dispersible graphene conductive powder by cyclone separator (4). USE - Preparation method of highly dispersed graphene conductive powder of lithium battery (claimed). ADVANTAGE - The good electron transport duct and ion transmission channel are enhanced. The power performance of lithium ion battery is improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a lithium battery. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view illustrating the preparation process of highly dispersed graphene conductive powder.
