The invention relates to a negative electrode additive of an alkaline zinc-manganese dry battery, a negative electrode zinc paste containing the negative electrode additive and an alkaline zinc-manganese dry battery. The negative electrode additive comprises a component A and a component B, wherein the component A is a high-carbon alcohol defoaming agent, and the component B is high-carbon fatty alcohol polyoxyethylene ether and / or alkylphenol polyoxyethylene ether. On the basis of a battery negative electrode reaction mechanism, the high-carbon alcohol defoaming agent and the high-carbon fatty alcohol polyoxyethylene ether and / or alkylphenol polyoxyethylene ether are added into a negative electrode formula, and therefore, electrochemical polarization is reduced, the passivation of a zincsurface under a high-power discharge condition is avoided, and the high-power discharge performance of the alkaline manganese battery is greatly improved.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a negative electrode additive for an alkaline zinc-manganese dry battery, a negative electrode zinc paste containing the same, and an alkaline zinc-manganese dry battery. Background technique [0002] Alkaline-manganese batteries refer to primary batteries that use manganese dioxide as the positive electrode, zinc as the negative electrode, and potassium hydroxide as the electrolyte. Alkaline-manganese batteries have the characteristics of high quality and low price, easy to use, safety and environmental protection, and are widely used in small electrical appliances in daily life. For example, the maximum pulse output current of LR6 alkaline-manganese battery is 1.5A, and the continuous output current is only 1A. In recent years, with the increase in the number of digital electronic products, there are higher requirements for the high-power discharge performance of the battery....
