Abstract

The invention relates to the technical field of chemical power supply materials and in particular relates to a welding-free storage battery and a production method thereof. A continuous type welding-free lead storage battery pole group comprises continuous type positive electrode plates, continuous type negative electrode plates, a single-body-spanning connection sheet, a continuous type bipolar pole plate and a separation plate, wherein the continuous type bipolar pole plate is composed of the continuous type positive electrode plates, the continuous type negative electrode plates and the separation plate, which are inserted and matched. According to the welding-free storage battery provided by the invention, an integrated continuous design is carried out on the lead storage battery polegroup and a welding procedure of a plurality of pieces of the positive electrode plates or negative electrode plates in a pole plate group during a storage battery production process is eliminated; aserial and parallel connection welding procedure of bridge-spanning welding, wall-penetrating welding and the like of a plurality of single bodies of the storage battery is also eliminated. Therefore,the use amount of lead of the storage battery is reduced and sheet falling and missing welding phenomena do not happen between the pole plate group of the storage battery and the single bodies; the product quality and reliability of the storage battery are effectively improved.

Description

technical field [0001] The invention relates to the technical field of chemical power source materials, in particular to a welding-free storage battery and a manufacturing method thereof. Background technique [0002] The pole group in the battery cell is formed by overlapping several positive plates, several negative plates and separators. The pole group is the key component of the lead-acid battery. The pole plate in the traditional lead-acid battery pole group is a single-piece structure. These positive and negative plates need to be further welded separately to form a single pole group. For multi-cell batteries, each cell pole group needs to be further welded across the bridge or through the wall to achieve a higher nominal voltage. The above-mentioned processing method not only consumes a large amount of lead raw materials, but also is prone to problems such as chip drop and solder leakage. In view of this, we propose a welding-free storage battery and a manufacturing...
