▎ 摘　　要

NOVELTY - The device has a frame body (1) horizontally and movably connected with a working table (3) through a clamping structure. A side of the frame body is vertically fixed with a mounting piece (6) that is horizontally fixed with a top component (7). A lower portion of the mounting piece is provided with a brush head (19) for brushing cathode slurry to a copper foil on the working table. A walking component is fixed between a pressing component and the brush head. A lower portion of the walking component is provided with a heating disk for drying coated cathode slurry. USE - Device for preparing graphene battery cathode sheet. ADVANTAGE - The device ensures that the pressing component drives the walking component to move along the horizontal direction so as to drive the copper foil paved on the working table to walk. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene battery negative plate. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the device.
