Control measures for roll bending of lithium batteries

　　1. Optimize coating process:

　　By improving the coating process, the difference in active material surface density between the edge and the middle area of the polarizer is controlled to reduce uneven edge thickness. At the same time, strengthen quality control during the coating process to ensure that the surface of the polarizer is uniform, free of impurities and defects.

　　2. Accurate control of rolling process parameters:

　　Accurately set parameters such as pressure, speed, and temperature of the roller according to the material and process requirements of the polarizer. By real-time monitoring and feedback adjustment, ensure the stability and reliability of various parameters during the rolling process. In addition, advanced automation control systems can be used to achieve precise control and optimized adjustment of roll parameters.

　　3. Strengthen equipment maintenance and calibration:

　　Regularly maintain and calibrate the rolling equipment to ensure that it is in good condition. Check the coaxiality, cylindricity, and surface roughness of the rolling mill, and replace the severely worn rolling mill in a timely manner. At the same time, strengthen the training and management of equipment operators to improve the standardization and accuracy of equipment operation.
