▎ 摘　　要

NOVELTY - A graphene current collector preparing method involves preparing oxidized graphene solution by oxidative intercalation method, followed by concentrating by dialysis, packing in a container and opening the container mouth in a reductive atmosphere. The graphene gel is spin-coated onto a smooth substrate to control film thickness and gel density of a precursor graphene gel film using a film coating machine, followed by placing in a blast drier, introducing reducing gas, coating, dried by blowing, evaporating, drying, circulating, reducing, stripping and rolling to obtain finished product. USE - Method for preparing a graphene current collector. ADVANTAGE - The method enables preparing the graphene current collector with high mechanical strength, better flexibility, better conductivity, high chemical stability and corrosion resistance effect. DETAILED DESCRIPTION - A graphene current collector preparing method involves preparing oxidized graphene solution by oxidative intercalation method, followed by concentrating by dialysis to obtain a high viscous graphene liquid crystal yellow sugar syrup, packing in a container and opening the container mouth in reductive atmosphere. The graphene gel is spin-coated onto a smooth substrate to control the film thickness and gel density of a precursor graphene gel film using a film coating machine. The precursor graphene gel film is placed in a blast drier, followed by introducing reducing gas, coating on the smooth substrate, drying by blowing, evaporating, drying, circulating, reducing, stripping and rolling to obtain finished product.
