Keep Improving: Production Process And Quality Control of Cylindrical Lithium Batteries

In the production process of cylindrical lithium batteries, process and quality control are the key to ensure product performance and safety. As a professional cylindrical lithium battery manufacturer, we use advanced production processes and strict quality control systems to ensure that each battery meets the highest standards.

Production process

Electrode preparation: We use high-precision coating equipment to ensure uniform coating of electrode materials. By precisely controlling the coating thickness and density, we are able to achieve high energy density and long cycle life of the battery.

Winding process: During the winding process, we use automated equipment to accurately wind the positive and negative electrode sheets and separators into a cylindrical shape. This process requires extremely high precision to ensure that the internal structure of the battery is tight and defect-free.

Assembly and packaging: The assembly and packaging process of the battery is carried out in a dust-free workshop to prevent any impurities from entering the battery. We use advanced laser welding technology to ensure the sealing and safety of the battery.

Formation and capacity separation: After the battery production is completed, we perform formation and capacity separation tests. This process activates the battery's chemicals through multiple charge and discharge cycles and selects batteries with consistent performance.

Quality Control

Raw Material Testing: We conduct strict testing on all raw materials to ensure that they meet international standards. Only raw materials that pass the test can enter the production line.

Process Control: During the production process, we implement full-process monitoring to ensure that every link meets the process requirements. Any product that does not meet the standards will be immediately eliminated.

Finished Product Testing: Each battery undergoes multiple tests before leaving the factory, including voltage, internal resistance, capacity and safety performance. Only batteries that pass all tests can be delivered to customers.

We are well aware that only through strict production processes and quality control can high-performance and high-safety cylindrical lithium batteries be produced. We will continue to uphold the spirit of excellence and provide customers with the best products and services.
