Abstract

The invention discloses a continuous type welding-free lead storage battery pole plate and a manufacturing method thereof. The continuous type welding-free lead storage battery pole plate is characterized in that a continuous type lead storage battery grid is adopted and comprises a plurality of plate coating areas (2); the adjacent plate coating areas (2) are connected by a connecting area (3); one end or both ends of the continuous type lead storage battery grid are provided with terminal areas (1); the plate coating areas (2) and the connecting areas (3) are integrally formed; each plate coating area (2) of the continuous type lead storage battery grid is coated with an active matter layer, so as to obtain a pole plate area. The continuous type welding-free lead storage battery pole plate has the advantages that by adopting the integrated continuous type design, the procedure of welding multiple pole plates in a pole plate group of a single unit in the production process of the storage battery is eliminated, and the serial and parallel welding procedures of bridge-crossing welding, wall-penetrating welding and the like between multiple units of the storage battery are also eliminated; the lead usage amount of the storage battery is effectively reduced, the piece falling and welding missing in the pole plate group and between the units of the storage battery are avoided, andthe quality and reliability of the storage battery product are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of chemical power source materials, and relates to a continuous welding-free lead storage battery plate and a manufacturing method thereof. Background technique [0002] The pole plate is the key component of the lead-acid battery. The pole plate used in the traditional lead-acid battery is a single-piece structure. The battery pole plate group is composed of multiple positive and negative plates and separators. The positive and negative electrodes in the plate group The 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. [0003] Some people have carried out research on continuou...
