Problems solved by technology

Although the equipment used in this process is relatively cheap, the quality consistency of the positive and negative plates produced is poor in terms of capacity and size. , the appearance quality is not good, and when the designer considers designing the battery, the final rated capacity of the battery can only be guaranteed by increasing the rated capacity of the battery by 10% to 20%. The material consumption is large, so the cost remains high, which also greatly affects Quality of products

Abstract

Disclosed is a method for making block-type pole plates for pocket type cadmium-nickel alkaline accumulators which comprises the steps of: getting positive and negative pole plates after packing, assembling and embossing, cutting, fixing and punching. The positive and negative pole plates of pocket type cadmium-nickel alkaline accumulators that made in same batches and types has tolerance less than 2% after assembled.

Description

technical field [0001] The invention belongs to a method for manufacturing a polar plate of a storage battery, and relates to a method for manufacturing a bag-type cadmium-nickel alkaline storage battery. Background technique [0002] In the prior art, the bag-type nickel-cadmium alkaline storage battery is a very important series among the nickel-cadmium alkaline storage battery, which not only has a large output, but also has a wide range of applications and is important. The positive and negative plates of bag-type cadmium-nickel alkaline batteries are currently widely used in the process route of "coating powder, embossing strips, shearing, fixing ribs, cutting ribs, and stamping", namely: (1) powder coating, Wrap the powdered positive and negative active materials uniformly mixed in a specific proportion in a flat perforated steel strip, and process them into a certain length of positive and negative plate strips; These bag-shaped long strips are stacked together to fo...
