NOVELTY - The utility model claims a coating graphene of lithium battery pole piece, comprising a frame body, the inner top surface of the frame body is slidingly connected with a sliding block, the bottom surface of the sliding block is provided with a first cylinder and a cylinder, the bottom surface of the first cylinder is provided with a plurality of nozzles, the cylinder is inserted with a movable rod, the bottom surface of the movable rod is provided with a scraping plate; the inner top surface of the frame body is provided with two telescopic rods, the extending end of the telescopic rod is provided with a connecting plate, one side opposite to the two connecting plates is provided with a pressing rod, the two telescopic rods are sleeved with a spring. The utility model model presses the pressure rod on the two ends of the pole piece, the spring continuously pushes the connecting plate, the pressure rod presses the pole piece, so as to avoid the effect of affecting the coating caused by the displacement of the pole piece when coating; adjusting the distance between the scraping plate and the pole piece according to the requirement; then moving the sliding block to drive the scraping plate to move, making the scraping plate uniformly spread the slurry on the pole piece, making the thickness of the paste coated by the pole piece consistent.
