Storage battery with light side negative plates as well as lamination method thereof

Abstract

The invention relates to a storage battery with light side negative plates as well as a lamination method thereof. The storage battery comprises a shell as well as polar groups arranged in the shell, wherein the polar groups comprise negative plates, paper blocking plates and positive plates; the negative plates comprise plate surfaces and plate ears, and include two side negative plates and middle negative plates; the thicknesses of the two side negative plates are less than the thicknesses of the middle negative plates; the weights of the two side negative plates are less than the weights of the middle negative plates. According to the invention, the two side negative plates are lighter than the middle negative plates, so that the lead using quantity can be reduced; the normal using of each positive plate is ensured; the battery acid content is improved; the battery capacity is increased; the phenomena of expansion and deformation of too fast water loss of the battery are reduced; the service life of the battery is prolonged; manual lamination is replaced by mechanical automation; five automatic conveying belts in the storage battery with light side negative plates respectively correspond to the corresponding polar plates or the paper blocking plates or the polar groups, so that the lamination sequence of the positive and negative polar plates and the paper blocking plates are difficult to be disordered; the product quality is ensured; the mechanical lamination of the side negative plates and the middle negative plates cannot lead to disorder; the cost is saved.

Description

technical field [0001] The invention relates to the field of storage battery production, in particular to a light-side negative plate storage battery and a stacking method thereof. Background technique [0002] At present, the thickness of the positive plate and the thickness of the separator inside the conventional battery are the same, the positive plate is thicker than the negative plate, the negative plate is one more than the positive plate, the thickness and weight of the negative plate are the same, and the weight of the negative plate on both sides is the same as that in the middle . The positive and negative plates are separated by paperboards, which are used to store sulfuric acid and isolate the positive and negative plates to avoid short circuit; the positive and negative plates are made of porous lead materials, and under the action of sulfuric acid, the positive and negative plates react with each other to achieve storage or release power function. If only th...

Problems solved by technology

But the negative plates on both sides have only one positive plate to react with it, and there is no positive plate to react with it on the outer side, so the two negative plates on the side have the same weight as the negative plate in the middle, which is a waste of material

Secondly, because only the inner side of the negative plate on the side has a positive plate reaction, the positive plate close to it is sandwiched between two negative
