Integrated battery tank preparation method

Abstract

The present invention relates to an integrated battery tank preparation method, which comprises: 1, carrying out one-time injection molding to obtain a housing with an opening on the bottom portion, wherein the housing is provided with electrode plate group tank separation plates, an electrolyte distribution channel, electrolyte injection holes, post terminal holes, and post terminal pole separation plates; 2, carrying out one-time injection molding to obtain a large cover plate with a metal inert; 3, placing electrode plate groups into electrode plate group tanks, and adhering the bottom portion of the housing and a bottom plate to form an integrated body; and 4, adhering the large cover plate and the housing top surface periphery of the electrolyte distribution channel to form an integrated body. According to the present invention, the housing obtained through the one-time injection molding is used, the internal of the housing is the electrode plate group tanks separated by the electrode plate group tank separation plates, and the top portion of the housing is provided with the post terminal holes, the post terminal hole separation plates for separating the adjacent post terminal holes, and the electrolyte injection holes, such that the housing has the electrolyte distribution effect and the electrode plate group container effect so as to make the whole battery tank structure be simplified and compact; and with the post terminal pole separation plates, the battery short circuit caused by the contact of the terminal posts is effectively prevented so as to ensure the battery safety.

Description

technical field [0001] The invention belongs to the technical field of chemical power sources, in particular to a method for preparing an integrated battery tank. Background technique [0002] In chemical power sources, especially zinc-silver reserve batteries have unique characteristics such as high specific energy, high specific power, high current discharge, stable discharge voltage, high voltage accuracy, good reliability and safety, etc., and are widely used in various fields. Zinc-silver reserve batteries are generally composed of welding wire sockets, gas generators, liquid reservoirs, combined plate sets, electric heaters, battery pack casings and other components. Among them, the combined plate group is composed of a plurality of single plate groups (ie, single cells) in series, and is a key component in the battery pack, that is, the source of electric energy of the battery pack. In order to ensure that the battery pack can be stored for a long time, the battery p...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the known methods for preparing integrated battery tanks adopt a structure in which multiple parts are assembled into one body. The battery tank with this structure has the problems of complex structure, large volume, and poor sealing, which ultimately affects the overall performance of the zinc-silver reserve battery.
