Problems solved by technology

[0004] Often when conducting material verification experiments, the number of material samples provided by the material manufacturer is small, and there is not enough material for size adjustment, and then there will be many positive and negative electrodes with dressings on the tabs, and the dressings on the tabs will cause damage. There are the following problems: 1. Normal ultrasonic welding cannot be carried out. When the dressing is carried on the lug of the pole piece for ultrasonic welding, it is easy to cause false welding or even fall off; 2. It cannot meet the principle that the negative dressing must cover the positive dressing

Abstract

The invention discloses a method for removing a dressing at a tab part of a pole piece for an experiment. The method specifically comprises the following steps of a preparation operation step, a stripping operation step and a post-treatment operation step. The stripping operation comprises the following steps that a, a container is placed on one side of an operation table top, hot water at the temperature of 60-80 DEG C is poured into the container, and the distance between the liquid level of the hot water and the upper edge of the container is 2-3 cm; b, the tab of the pole piece is placed at the lower part, the tab of the pole piece is slowly put into hot water to a specified position, stays for 15-20 seconds and then is taken out; c, the dressing layer on the tab of the pole piece treated in the step b isscraped off by using a plastic hard board; and d, the tab of the pole piece treated in the step c iswiped by using a rag, toilet paper is dipped in a small amount of alcohol, and the two sides of the tab arewiped cleanly. The method can be used for removing the dressing carried by the tab part of the pole piece due to special reasons, and is simple in removal method and suitable for being used in laboratories.

Description

technical field [0001] The present invention relates to a method for removing the dressing on the lugs of pole pieces for experiments, in particular to a dressing used for removing the lugs of the positive and negative poles of lithium-ion batteries due to special reasons, and is mainly used in It is used for experimental testing of materials, which can effectively increase the number of battery products when a small amount of raw materials are used, and is of great help to fully verify the performance of materials. It is suitable for the method of removing the dressing on the pole piece and ear part for the experiment of stacked lithium-ion batteries, which belongs to new energy. The field of battery technology. Background technique [0002] In recent years, with the increasing scarcity of petroleum resources and increasingly serious environmental pollution, it is imminent to develop new energy sources to replace traditional petrochemical energy sources. In this context, it...
