By adjusting voltage, electrostatic spraying needle head number of the needle head, transmission speed and other process parameters, the device can make the thickness of the coating more than 10 nm accurate and adjustable, reduce the internal resistance of the current collector and the electrode material contact and greatly reduce the production cost. DETAILED DESCRIPTION - Production equipment of graphene-coated conductive current collector has a spraying unit, the spraying unit comprises a slurry barrel (2), the top is provided with an opening. Agitator (1) is arranged on the outer side of the top of the slurry barrel, and whose stirring rod extends into the slurry barrel from the top opening of the slurry barrel. Conduit, one end of which is communicated with the bottom of the slurry barrel, and the other end is communicated with an electrostatic spraying needle (7), which is arranged inside the shell (6). The shell is parallel to the spraying direction of the electrostatic spraying needle, and two opposite walls are provided with notches, the notches being perpendicular to the spraying of the electrostatic spraying needle direction. Propulsion and flow restriction device for controlling the flow rate and flow of the paint in the conduit. Drying device (8) is arranged outside the shell and is close to one of the slots. The production equipment also includes an atmospheric thermal reduction treatment device (9), which is arranged outside the drying device and at a side away from the shell. Guide rail (11), two ends of which respectively pass through one of the slots on the shell, and two ends of which are respectively connected to the first winding wheel (5) and the second winding wheel (13). The first winding wheel is arranged outside the shell and at the side away from the drying device. The second winding wheel is arranged outside the atmospheric thermal reduction treatment device, and at a side away from the drying device. The conveying direction of the guide rail is from the first winding wheel to the second winding wheel. The guide rail passes through the drying device and the atmospheric thermal reduction treatment device. Driving device (12) is provided between the atmospheric thermal reduction treatment device and the second winding wheel, and is used for driving the conveyance of the guide rail.
