Description

Technical Field

[0001] The utility model belongs to the technical field of soft-pack battery cleaning, and in particular relates to a laser cleaning fixture for a pole ear of a new energy soft-pack battery. Background Art

[0002] Common new energy batteries include lithium-ion batteries and sodium-ion batteries. Sodium-ion batteries are secondary batteries that mainly rely on the movement of sodium ions between the positive and negative electrodes to work, similar to the working principle of lithium-ion batteries.

[0003] In the process of liquid injection packaging, soft-pack batteries using the lamination process will cause the tabs to be contaminated with electrolyte, and the electrolyte will corrode the tabs of the soft-pack batteries. The dirt and corrosion of the tabs will have a serious impact on the subsequent formation and capacity separation of the battery, affecting the battery performance. Traditional cleaning methods are not only inefficient, but also have unsatisfactory cleaning effects. Using lasers to clean the tabs of soft-pack batteries is not only more environmentally friendly, but also has a wider range of applications. However, when using lasers to clean soft-pack batteries, the position of the laser is not convenient to adjust, making it difficult to clean the tabs in all directions, which can easily affect the cleaning effect.
