Lithium battery, as an important energy storage device, has been widely used in modern society. Its manufacturing process control technology is the key to ensure battery performance and safety. This article will analyze the manufacturing process control technology of lithium battery, including coating, lamination, slitting, chemical formation and volume separation.

Coating Technology

coating Technology is one of the key links in the manufacturing process of lithium batteries. Through coating technology, the electrode materials of positive and negative electrodes are evenly coated on aluminum foil or copper foil to form the positive and negative electrodes of the battery. The coating process needs to control the coating thickness, uniformity, drying time and other parameters to ensure the performance and stability of the electrode.

Lamination technology

lamination technology is to stack the positive and negative electrode electrode plate and the diaphragm layer together according to the design specifications to form the cell structure of the battery. Lamination technology needs to control lamination layers, compaction strength and alignment degree to ensure compact and uniform structure of cell and avoid internal short circuit or electrode material damage.

Slitting technology

slitting technology is to cut lamination good battery pieces into appropriate sizes to meet the needs of different types of batteries. The cutting process needs to accurately control the cutting position, angle and precision to ensure the accurate size of the battery slice and avoid waste and bad products.

formation technology

the forming technology is to form the cut battery pieces, including embossing, hot pressing, molding and other processes. The formation process needs to control parameters such as temperature, pressure and time to make the battery sheet form well and ensure the structure and stability of cell.

Capacity distribution technology

separation technology is to test the capacity of the formed battery to ensure that the capacity of the battery meets the design requirements. The separation process needs to accurately control the precision and stability of the test equipment, timely discover and eliminate batteries with unqualified capacity, and ensure the product quality and performance.

The importance of manufacturing process control technology

manufacturing Process Control technology plays a vital role in lithium battery manufacturing. The stable, safe and reliable performance of the battery can be ensured by accurately controlling the links such as coating, lamination, slitting, chemical formation, and volume separation. Coordination and precise control between each link are the key to ensure the quality and production efficiency of lithium batteries.

Lithium battery manufacturing process control technology it is a key link to ensure battery performance and safety.Processes such as coating, lamination, slitting, chemical formation, and volume separation need to be accurately controlled to ensure that the quality and performance of the battery meet the requirements. The continuous improvement and innovation of manufacturing process control technology will further promote the development and progress of lithium battery industry.
