Abstract

The invention discloses a processing technique of lead-acid green plate batteries, and belongs to the technical field of lead-acid batteries. The processing technique is characterized in that lead paste is prepared firstly; the lead paste comprises the following components in percentage by mass: 95.8-91.5 of lead powder, 0.9-2 of dilute sulfuric acid, 0.5-1 of short fibers, 2.5-5 of tetrabasic lead sulfate and 0.3-0.5 of selenium; semi-finished products are obtained by using the lead paste to coat, cure and assemble; then the charging formation processing is implemented; finally, finished products are obtained through water washing. The solution reduces the power consumption of the formation part in the production process, and the power saving effect can achieve 30%; the water washing consumption is also reduced for 70%; about 16% of production period is shortened; the manpower cost of corresponding technique links and the hardware scale of the formation shop are necessarily decreased; considerable economic benefit is achieved. On the other hand, the charging-discharging circulation times is increased.

Description

technical field [0001] The invention relates to the field of accumulators, and relates to a processing technique for a lead-acid raw plate battery. Background technique [0002] Lead-acid batteries have already possessed quite mature technology, and have the characteristics of high reliability, large capacity, strong discharge capacity at high rate, good temperature coefficient, many charge and discharge cycles, and reasonable cost. They are widely used in motor vehicles, industrial and mining equipment, electric power reserve systems, etc. [0003] The main type of lead-acid battery, its core components include the plate, the plate is made of a grid made of lead material, and then filled with lead paste on the grid to obtain a green plate, and finally formed. The current raw electrode plates need to be chemically treated before being loaded into the battery body, and then can be packaged after being washed and dried. The chemical synthesis process before packaging often c...
