Gasket, coating device, pole piece, battery monomer and electric device

The invention relates to a gasket, a coating device, a pole piece, a battery monomer and a power utilization device. The first ends of the two side striker plates are connected to the two ends of the main plate respectively, and an outlet is formed between the second ends; the at least one spacing plate is arranged between the two side baffle plates at intervals, one end of the spacing plate is connected with the main plate, and the other end of the spacing plate extends to the outlet and divides the outlet into at least two sub-outlets; and the baffle groups are in one-to-one correspondence with the spacing plates and are convexly arranged on the same sides of the corresponding spacing plates along the thickness directions of the spacing plates. According to the invention, the plurality of sub-tank groups are respectively used for independently storing slurry and do not influence each other; each sub-groove group corresponds to one feeding hole, and different sub-groove groups realize coating of different co
