　　What are the precautions for UPS 18650 battery 3500mah production process?

　　UPS 18650 battery 3500mah production process precautions

　　The UPS 18650 battery 3500mah production process has some differences depending on the different 18650 battery 3500mah manufacturers, but because the principles are the same, the main 18650 battery 3500mah production processes are basically the same, generally including: batching, coating, rolling, cutting, and slitting , welding tabs, winding, packaging, baking, liquid injection, formation, molding, volumetric testing and other processes.

　　Among the necessary steps in the UPS 18650 battery 3500mah production process, five aspects should be paid attention to from material selection to volumetric testing after molding.

　　1. Improve the physical and chemical structure of the positive and negative active materials, which is the basic link in the 18650 battery 3500mah production process;

　　2. The high bonding strength of the electrode coating is conducive to reducing the cycle capacity decline rate. This is the most technical process in the 18650 battery 3500mah production process;

　　3. Optimization of the composition of the electrolyte. The UPS 18650 battery 3500mah production process requires the electrolyte to maintain capacity and extend battery life;

　　4. After the battery material preparation is completed, the 18650 battery 3500mah production process enters the assembly process. At this time, it should be noted that the negative electrode capacity is slightly larger than the positive electrode capacity;
