Description
Technical Field
The utility model relates to an alkaline environmental protection zinc-manganese cell manufacturing field especially relates to an alkaline environmental protection zinc-manganese cell mass flow body.
Technical Field
With the increasing awareness of environmental protection, people purchase and use products which tend to be environment-friendly. The alkaline environment-friendly zinc-manganese battery is one of the environment-friendly products and is more and more favored by consumers. The current collector is one of the most important components in the battery, and mainly serves as a carrier for electron flow of the positive electrode and the negative electrode of the battery. The performance and conductivity of the battery can directly affect the discharge pressure and discharge time of the battery. The current collector of the alkaline environment-friendly zinc-manganese battery on the current market and the alkaline environment-friendly zinc-manganese battery are assembled to have the problem of untight sealing, and the problem of liquid leakage caused by chemical reaction inside the battery also exists, and the problems directly influence the service life of the battery. Moreover, the problems of substandard battery discharge pressure and short discharge time caused by the current collector structure problem also occur frequently.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a current collector of alkaline environmental protection zinc-manganese battery with good conductivity, long discharge time and long service life. The technical scheme is as follows:
the alkaline environment-friendly zinc-manganese battery current collector comprises a cover plate, a neck part and a needle body, wherein the diameter of the neck part is larger than that of the needle body, and a natural arc transition part is arranged at the joint of the neck part and the needle body; the needle body is vertical to the cover plate, the curvature of the needle body is less than 0.1mm, and the ovality of the needle body is less than 0.04mm; the cover plate, the neck, the arc transition part and the needle body are of an integrated structure, and a protective layer is plated on the surfaces of the cover plate, the neck, the arc transition part and the needle body.
Preferably, the cover plate, the neck, the arc transition part and the needle body are made of pure copper.
Preferably, the protective layer is indium, and the indium can well protect a current collector in the battery, so that the chemical reaction of the current collector in the battery is greatly reduced.
The arc transition part can well ensure that the current collector is convenient, smooth and tightly matched in the process of assembling the alkaline environment-friendly zinc-manganese battery. Has obvious effect on improving the production efficiency and the product quality.
The utility model provides an in the mass flow body because the diameter of neck is greater than needle body diameter to they belong to the integrated configuration so can not adopt general method to make out, the utility model relates to a personnel have designed special mould, with the neck part of needle body inflation processing and obtain the neck structure of mass flow body in the mould.
The utility model provides a pair of alkaline environmental protection zinc-manganese dioxide battery mass flow body can reach good closely cooperating with the battery at the in-process of assembling the battery, has overcome the weeping problem because of the leakproofness is not good and takes place to the product quality of battery has been improved and the life of battery has been prolonged. Meanwhile, the alkaline environment-friendly zinc-manganese battery current collector also has the advantages of simple structure, high conductivity, capability of effectively improving the discharge time of the battery, stable performance and the like.
