Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide an alkaline zinc-manganese battery that prevents leakage due to over-discharge caused by series use on the premise that the size and appearance meet the current national standards, and overcomes the problem of existing alkaline zinc-manganese batteries used in series. , due to the uncontrolled over-discharge depth, the unexpected occurrence of over-discharge depth is too high, resulting in a large amount of gas evolution and liquid leakage in the battery; the semiconductor diode is connected in series with the ordinary alkaline manganese battery, and the dead-zone voltage property of the low-cost semiconductor diode is used to fully limit The lower limit of the voltage of each battery during the discharge process fundamentally reduces the over-discharge depth of the battery and the over-discharge leakage rate

Abstract

The invention discloses an alkaline zinc-manganese battery preventing overdischarge liquid leakage caused by the application in series, and aims at solving the problems of the liquid leakage caused by a great amount of precipitated gas inside the battery after the battery is over-discharged. The alkaline zinc-manganese battery comprises an overdischarge protection part and an alkaline zinc-manganese battery main body, wherein the overdischarge protection part is mainly of a semiconductor diode, and the protection part and the alkaline zinc-manganese battery main body are serially connected to obtain the alkaline zinc-manganese battery with improved discharging leakage prevention performance. The alkaline zinc-manganese battery is simple in preparation process, and the overdischarge liquid leakage prevention performance caused by the application in series of the alkaline zinc-manganese battery can be remarkably improved.

Description

technical field [0001] The invention relates to an alkaline zinc-manganese battery, in particular to an alkaline zinc-manganese battery that prevents liquid leakage caused by overdischarge caused by serial use. 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] For high current performa...
