The invention discloses a device for performing surface treatment on a pole piece of a lithium battery. In one piece-brushing process, the front side and the reverse side of the pole piece can be treated simultaneously, so that the treatment efficiency can be improved and the treatment quality can be guaranteed. The device comprises a machine frame, a workbench, an upper sponge, a lower sponge, a negative pressure device and an upper sponge driving cylinder; the lower sponge is fixed on the workbench; the upper sponge driving cylinder is arranged on the machine frame; a piston rod of the upper sponge driving cylinder faces downward; the bottom of the piston rod is fixedly connected with the upper sponge; the upper sponge is positioned above the lower sponge; the negative pressure device comprises an air compressor and a suction pipe; the suction pipe is inserted upward from the bottom of the workbench; and the pipe orifice of the suction pipe is positioned in the lower sponge. The process for brushing the piece is improved, a technology for automatically brushing the two sides of the piece simultaneously is adopted, two sponge plates which are correspondingly arranged up and down are used and when dust adsorbed to the sponge plates is more, the sponge plates can be replaced at any time. The device is high in quality for cleaning the pole piece, and high in yield, and can timely remove the dust and debris and obviously improve the quality of the pole piece, and the battery manufactured by the pole piece is low in short circuit rate.
