Polymer battery tab repair clamp and tab repair method

Abstract

The polymer battery tab repairing clamp comprises a first shell, a second shell is arranged on the outer wall of one side of the first shell, anti-skid stripes are fixedly installed on the upper surface of the first shell and the upper surface of the second shell, a step structure is arranged on the upper surface of the first shell, and two sets of welding point positions are arranged on the upper surface of the first shell; the first shell is provided with a clamping groove through the welding point, and the first shell is provided with a copper block through the clamping groove. According to the polymer battery tab repairing clamp, a specific nickel strap can be effectively connected to a battery cell tab, so that the overall size and length of the battery cell tab are increased, the purpose that the battery cell can be continuously used can be achieved, the repairing problem of the battery cell due to the fact that the polymer tab is broken is effectively solved, and meanwhile, the repairing efficiency of the battery cell is effectively improved according to batteries of different sizes. And the overall positioning structure is automatically adjusted, so that the use requirements of batteries with different specifications are met, and the overall flexibility and adaptability are greatly improved.

Description

technical field [0001] The invention relates to the technical field of polymer battery tabs, in particular to a fixture for repairing polymer battery tabs. [0002] The invention also relates to a method for repairing tabs of polymer batteries. Background technique [0003] Tabs are a raw material for lithium-ion polymer battery products. There are three kinds of materials: the positive electrode of the battery uses aluminum material, the negative electrode uses nickel material, or the negative electrode also has copper nickel-plated material, and they are all composed of film and metal strip. The film is the insulating part on the tab, and its function is to prevent short circuit between the metal strip and the aluminum-plastic film when the battery is packaged, and to prevent leakage by heating and sealing with the aluminum-plastic film during packaging. [0004] At present, in the production and manufacture of polymer batteries, many battery tabs are found to be broken....

AI Technical Summary

Problems solved by technology

As a result, the battery cells cannot be connected to the protection board, making the battery cells unusable. Although the current treatment methods in the same industry are different, the battery cells with broken tabs during the production process cannot be connected to the protection board due to the short tabs. The battery cells basically belong to Scrap status

Unable to continue to use, the solution of each manufacturer is to control the occurrence of defective products

Does not solve the problem of repairing defective products

[0005] At the same time, in the process of repairing it, it is also impossible to adjust the structure of the overall fixture independently according to the different battery sizes of different models and specifications, making some types of batteries unusable, thus greatly shortening its polymer capacity. The scope of use of the battery tab rework fixture reduces the overall flexibility and adaptation
