　　Solution to lithium coating bubbles in lithium batteries

　　1. Improve the cleanliness of the production environment: Strengthen the cleaning and maintenance of the production environment, reduce the mixing of impurities such as dust, moisture, and burrs. Adopting measures such as automatic feeding equipment, sealed storage of slurry, and wearing dust-proof clothing to improve the cleanliness of the production environment. Strictly control the dust in the battery production environment and reduce the mixing of foreign objects.

　　2. Strengthen the airtightness of the production process: use automatic feeding equipment, reduce personnel involvement, and maintain the cleanliness of the slurry mixing workshop.

　　3. Proper storage and transportation of slurry: The stirred slurry should be sealed and stored to prevent foreign objects from entering.

　　4. Use of defoamer: add an appropriate amount of defoamer in the slurry to eliminate foam.

　　5. Optimize material selection: Choose suitable coating materials and solvents to ensure their volatility and wettability meet process requirements.

　　6. Strengthen mixing uniformity: thoroughly stir the slurry before coating to ensure a uniform and bubble free system. Vacuum stirring or ultrasonic stirring can be used to improve the mixing effect.

　　7. Improve drying process: Adjust parameters such as temperature and air volume in the drying chamber to ensure complete evaporation of the solvent. The drying effect can be improved by staged heating or extending the drying time.

　　8. Adjust process parameters: Adjust the coating rate, drying temperature, and other process parameters according to the actual situation to reduce the generation of bubbles. The optimal combination of process parameters can be determined through experimental verification and data analysis. Adjust process parameters: Reasonably adjust stirring speed, time, and coating speed to improve the leveling of the slurry.

　　Lithium coating bubbles in lithium batteries are one of the key issues that need to be paid attention to in the production process of lithium batteries. By optimizing material selection, strengthening mixing uniformity, improving drying processes, enhancing production environment cleanliness, and adjusting process parameters, the generation of bubbles can be effectively reduced, and the performance and safety of lithium batteries can be improved.

　　In the actual production process, it is necessary to closely monitor the changes in coating technology, adjust process parameters and operating methods in a timely manner to ensure the production quality of lithium batteries.
