Lithium battery manufacturing process: the front, middle and back three processes, accounting for nearly 35%/30%/35%

The production process of Li-ion battery is complex, and the main production process mainly covers the stirring and coating stage of electrode production (front section), the winding and liquid injection stage of core synthesis (middle section), and the packaging and testing stage of chemical packaging (back section), with a value (purchase amount) ratio of about (35~40%): (30~35)%: (30~35)%. The differences mainly come from different equipment suppliers, differences in the ratio of imported / domestic, etc. The process flow is basically the same, and the value volume share has deviations but is generally in line with the ratio.

The lithium equipment corresponding to the front process of lithium production mainly includes vacuum mixer, coating machine, roller press, etc.; the middle process mainly includes die-cutting machine, winding machine, laminating machine, liquid injection machine, etc.; the back process includes chemical formation machine, sub-volume testing equipment, process storage logistics automation, etc. In addition, the production of battery packs also requires Pack automation equipment.
