Production process and link of Shenzhen Mottcell new energy Technology Co.,Ltd

Lithium battery production process flow diagram detailed explanation. Specifically as follows: material preparation —— homogenate —— coating —— rolling —— cutting —— baking —— winding —— into the shell —— laser welding —— baking —— liquid injection —— precharge —— sealing —— cleaning —— aging —— full inspection —— storage —— shipment; —— mixing, coating, winding and testing as the main production process of lithium battery.

1, paste mixing is an important link of lithium ion battery equipment, lithium ion battery positive paste consists of adhesive, conductive agent, cathode material, negative paste is composed of adhesive, graphite toner, etc. The preparation of positive paste includes liquid and liquid, liquid and solid material mixing, dissolution, dispersion; paste dispersion quality, directly affect the quality and performance of lithium ion battery.

2. Coating determines the consistency and superiority of the battery, and occupies a technical position in the battery manufacturing. The coater used in manufacturing is the same regardless of the production (such as cylindrical or square) batteries; different types of batteries should be equipped with different types of comachine.

3. In addition to lithium ion battery winding machine, there are capacitor winding machine, textile winding machine, etc. According to the operation mode of the machine, it can be divided into manual winding machine, semi-automatic winding machine and fully automatic winding machine.

4. Testing items are becoming increasingly more important. Lithium ion battery is easy to burn or explode due to short circuit, overcharge, and will form finished batteries with protective plate in the application; In the application field with high energy density, lithium ion battery should be combined in series and parallel into lithium ion battery pack, managed by battery management system (BMS).

It can be seen that lithium ion battery production process is long, including more than 50 processes, and more than 50 kinds of equipment. The whole manufacturing lithium battery production process can be divided into four processes: pole production, cell assembly, cell activation detection and battery packaging. In the lithium battery production process, the pole production is the foundation, the cell production is the core, and the battery assembly is related to the quality of lithium battery finished products. The specific links of lithium battery production process include positive electrode pulp, negative electrode slurry, positive electrode plate, negative electrode plate, steel shell assembly, liquid injection and testing and packaging... of which electrode plate production related equipment is called front-end equipment, cell production is related to the mid-end equipment, cell activation detection and battery packaging equipment is back-end equipment.

Shenzhen Mottcell New Energy Technology Co., Ltd. Lithium battery production in recent years, to the integration, the whole line, automatic development, Yammu new energy to provide customers with standardized products, the traditional development methods can not cope with the rapid changing needs of customers.
