Abstract

The invention relates to the technical field of chemical power supply materials, in particular to a continuous solderless lead-acid battery electrode group and a manufacturing method thereof. The continuous solder-free lead-acid battery electrode group comprises a continuous positive electrode plate, a continuous negative electrode plate, a cross-unit connecting piece, a continuous bipolar electrode plate and a separator, wherein the continuous bipolar electrode plate is composed of a continuous positive electrode plate, a continuous negative electrode plate and a separator which are insertedand matched. A lead storage battery electrode group is integrally and continuously design, and that welding procedure of a plurality of positive plate or negative plates in the electrode plate group in the production process of the storage battery is eliminated, and the series and parallel welding procedures such as cross-bridge welding and through-wall welding between a plurality of monomers of the storage battery are also eliminated. This not only reduces the lead consumption of the battery, but also does not appear the phenomenon of chips falling off and missing welding between the electrode plate group and the monomer of the battery, which effectively improves the product quality and reliability of the battery. In addition, the electrode group of the invention has high manufacturing process efficiency and is convenient for production and processing.

Description

technical field [0001] The invention relates to the technical field of chemical power source materials, in particular to a continuous welding-free lead storage battery electrode group 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 continuous solde...
