Light side negative plate battery and lamination method thereof

Abstract

The invention relates to a light-edge negative-plate accumulator and a stacking method thereof. The accumulator includes a casing and an electrode group arranged in the casing. The electrode group includes a negative plate, a paper separator, and a positive plate. The negative plate Including the plate surface and the lug, the negative plate includes two side negative plates and a middle negative plate, the thickness of the side negative plates is smaller than the thickness of the middle negative plate, and the weight of the side negative plates is less than the weight of the middle negative plate. In the present invention, the negative plates on both sides are lighter than the negative plate in the middle, which can reduce the amount of lead, ensure the normal use of each positive plate, increase the acid content of the battery, increase the battery capacity, reduce the phenomenon of rapid bulging and deformation of the battery due to water loss, and increase the service life of the battery. , Mechanical automatic instead of manual stacking, the five automatic conveyor belts in the light-side negative plate battery stacking device correspond to the corresponding plates or separators or electrode groups, so it is not easy to confuse the stacking order of positive and negative plates and separators, The quality of the product is guaranteed, and the mechanical stacking of the side negative plates and the middle negative plates is not easy to cause confusion and saves costs.

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 plates, so the positive plate is easily overutilized, and the utilization rate of the positive plate near the negative plates on both sides Too fast, easy to cause softening failure

Therefore, the negative plates on both sides are as heavy as the negative plate in the middle, which not only wastes the material of the negative plate, but also causes premature failure of the positive plate close to it, affecting the service life of the battery
