Lithium battery production methods and laser production process analysis

Lithium batteries are produced and used in a wide range of applications to meet the detection requirements at home and abroad. Lithium battery production.jpg1. The solution to the negative electrode material must first separate the large particle size and ultrafine powder from the required particle size, prevent chemical reactions from occurring, and improve the safety of the lithium battery cell. The method of increasing the surface porosity of the material can increase the capacity by more than 10%, and at the same time, the safety performance of the lithium battery can also be improved when the C/A ratio remains unchanged. 2. Control of the pulping process The pulping process generally uses special chemical reagents to minimize the tension between the positive and negative slurry. Improve the compatibility between the groups and prevent the agglomeration of materials during the mixing process. During coating, the gap between the base material and the nozzle should be kept below 0.2mm, so that the surface of the plate formed is smooth and free of defects such as particles, dents, scratches, etc. The storage time of the slurry is maintained at more than 6 hours, and it is ensured that there is no self-agglomeration inside the slurry. The average slurry is the uniformity of the distribution on the substrate of the positive and negative electrodes of the lithium battery, which improves the consistency of the battery cell. In order to guard against danger, the laser production process of lithium battery is more suitable for production. Compared with traditional mechanical production, laser has the advantages of no tool wear, flexible cutting shape, edge quality control, higher accuracy and lower operating costs. Relative to the traditional die-cutting method, high-power, online laser cutting has no consumables, which greatly reduces the cost; in addition, the production speed is faster, which can greatly improve the processing efficiency; third, the flexibility is high, and the size of the lithium battery processing process can be Freedom in control. Lithium batteries, as the core components of new energy vehicles, directly determine the performance of the entire vehicle. With the gradual explosion of the new energy vehicle market, laser cutting machines will have great market potential in the future.
