Manufacturing process of high-power environment-friendly alkaline zinc-manganese dry battery

Abstract

The invention belongs to the field of alkaline zinc-manganese dry batteries, and discloses a manufacturing process of a high-power environment-friendly alkaline zinc-manganese dry battery. The process comprises the following steps of 1, uniformly mixing a positive electrode material of the alkaline zinc-manganese dry battery with a release agent, and carrying out compression molding to obtain a positive electrode ring; 2, inserting the positive electrode ring into a steel shell, filling the bottom of the steel shell with a blocking agent to form a blocking layer, inserting a diaphragm paper, enabling the outer wall of the diaphragm paper to be in close contact with the inner wall of the positive electrode ring, enabling the bottom of the diaphragm paper to be in contact with the blocking layer, and then injecting alkaline electrolyte into the diaphragm paper; and 3, injecting a negative zinc paste containing composite conductive emulsion into the diaphragm paper, assembling a negative electrode end, a sealing ring and a negative current collector copper needle into a sealing body, inserting the sealing body into the negative zinc paste, and sealing the positive steel shell and the sealing body to prepare the alkaline zinc-manganese dry battery. According to the alkaline zinc-manganese dry battery prepared by the scheme, the internal resistance of the battery is greatly reduced and the high-power discharge performance of the battery is improved through the negative electrode zinc paste with the composite conductive emulsion.
