Problems solved by technology

Hydrogen accumulates continuously in the battery. When the air pressure reaches the pressure of the explosion-proof ditch of the sealing ring, the explosion-proof ditch opens to leak liquid inside the battery. The leaked liquid will corrode the electrical appliances, and the leaked liquid will corrode the components, copper foil and solder joints on the electrical circuit board. Cause electrical appliances to be scrapped, resulting in losses much higher than the value of the battery itself, seriously affecting customers' confidence in the brand
Therefore, the manufacturers of alkaline zinc-manganese batteries control the metal impurities very strictly during the production process. However, if the metal impurities inside the battery are too high due to negligence, and after the high temperature detection is found, the batteries can only be isolated and scrapped in batches.
In addition to battery leakage in severe cases, alkaline zinc-manganese batteries may also suffer from poor electrical performance due to formula errors during the production process, which can be downgraded for use or scrapped in batches
Both of them will cause serious losses to the manufacturer, and even lead to the bankruptcy of the manufacturer in severe cases.

Abstract

The invention provides a novel maintainable alkaline zinc-manganese battery and a maintaining method of the alkaline zinc-manganese battery, and aims at solving the problem that when liquid leakage hidden danger occurs or the electrical performance is poor in the batch finished products of the alkaline zinc-manganese battery, the finished products can be only scraped. The alkaline zinc-manganese battery provided by the invention can be supplemented and maintained. When the condition that cylindrical alkaline zinc-manganese batteries in batch production have liquid leakage hidden danger due tocopper nails, zinc cream and positive electrode impurity existence is found, a corrosion inhibitor or other additives are injected into the maintainable alkaline zinc-manganese battery through an airpressure reverse sealing device; when the electrical property is insufficient, electrolyte or zinc cream can be injected; when the inside air pressure is very high, the pressure can be released; inertgas is injected; the battery self-discharging reaction is reduced; the risk of battery liquid leakage or explosion is reduced. The preparation process is simple; the battery batch rejection rate is comprehensively reduced; the loss of the alkaline zinc-manganese battery in the production process can be greatly reduced.

Description

technical field [0001] The invention relates to the field of chemical power sources, in particular to a maintainable alkaline zinc-manganese battery and a maintenance method for the alkaline zinc-manganese battery. Background technique [0002] The huge share of zinc-manganese batteries in the battery market is inseparable from its wide range of uses. It is the leading product of civilian primary batteries. Almost all low-voltage DC appliances can use alkaline manganese batteries as power sources. Alkaline zinc-manganese batteries have excellent electrochemical performance and high cost performance, and have been welcomed by consumers. Since mercury-free alkaline zinc-manganese batteries were put into the market, safe, environmentally friendly and high-performance alkaline zinc-manganese batteries have become more and more popular. The praise of the market, now and in the next few decades will be dominated by alkaline zinc-manganese batteries. [0003] The negative pole of ...
