Abstract

The invention relates to the technical field of batteries, in particular to an alkaline battery anode surfactant and a preparation method thereof. The alkaline battery anode surfactant comprises the following raw materials in parts by weight: 48-55 parts of potassium hydroxide, amphoteric metal oxide 18‑23 parts, 36‑41 parts of deionized water. The alkaline battery anode surfactant of the present invention is added to the battery formula, which can improve the utilization rate of the anode and the storage life of the battery at normal temperature, greatly reduce the leakage rate of the battery, and can effectively prevent the passivation of the battery anode during the manufacturing and storage process. At the same time, the concentration polarization phenomenon of the system reaction carrier electrolyte is prevented, and the preparation method is simple and convenient in operation, convenient in control, high in production efficiency and low in cost, and can be applied to industrialized production.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a method for an alkaline battery anode surfactant. Background technique [0002] Alkaline batteries are also known as alkaline dry batteries, alkaline zinc-manganese batteries, and alkaline-manganese batteries. They are the varieties with superior performance in the series of zinc-manganese batteries. Generally, the same type of alkaline battery is 3-7 times the capacity and discharge time of ordinary batteries, and the gap between the two is even greater in low-temperature performance. Alkaline batteries are more suitable for high-current continuous discharge and high working voltage. Occasions, especially suitable for cameras, flash lights, shavers, electric toys, CD players, high-power remote controls, wireless mice, keyboards, etc., have been increasingly widely used, [0003] However, the anode of the existing alkaline battery is prone to passivation during the manufactur...
