The process mainly includes the following steps: 1. Preparatory work 2. Size mixing 3. Prepare the electrode sheet 4. Dry 5. Equipped with button battery

In the manufacturing process of lithium-ion batteries, there are three very key items that must be strictly controlled: first, dust; Second, metal particles; The third is water. Dust and metal particles are not well controlled, which will directly lead to internal short circuit of the battery, fire and burning safety accidents; If the moisture is not effectively controlled, it will also cause greater harm to the battery performance and lead to serious quality accidents! Therefore, for the control of the water content of the main materials such as electrode sheets, separators, and electrolytes in the process, it is very critical, and there can be no relaxation. The following is detailed from three aspects: the harm of water to lithium batteries, the source of water in the process, and the control of water in the process.
