▎ 摘　　要

NOVELTY - Graphene negative electrode material preparation device includes a workbench (1), and a vertical plate (2) is installed at the top left and right ends of the workbench. A clamping mechanism (3) is respectively rotatably connected to the two vertical plates, and graphene (4) is installed between the two clamping mechanisms. A rotating mechanism (5) for driving the clamping mechanism to rotate is installed on the worktable. A grinding mechanism (6) is installed on the workbench below the graphene. USE - Graphene negative electrode material preparation device. ADVANTAGE - The graphene negative electrode material preparation device is convenient for fixing graphene and has high grinding efficiency for graphene. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic front view of graphene negative electrode material preparation device.
