Three-electrode battery



The utility model belongs to the technical field of lithium ion batteries and particularly relates to a three-electrode battery. The three-electrode battery comprises an upper cover, a lower cover buckled with the upper cover, a positive plate, a negative plate, isolating membranes, an electrolyte solution and a reference electrode, wherein the positive plate, the negative plate, the isolating membranes, the electrolyte solution and the reference electrode are arranged between the upper cover and the lower cover; the isolating membranes are arranged between the reference electrode, the positive plate and the negative plate, the reference electrode extends to the outer side of the upper cover, and an insulation membrane is arranged on the upper cover. The structural miniaturization of the three-electrode battery is achieved so as to achieve the better sealing performance, raw materials are saved, and the manufacturing time is shortened.
