What is the basic manufacturing process of lithium-ion batteries?

Objectively speaking, the production and manufacturing process of lithium-ion batteries is divided into three sections, one is pole piece construction, the other is battery cell construction, and the third is battery assembly. In the production process of lithium-ion batteries, pole piece construction is the basic, battery cell construction is the focus, and battery assembly is related to the quality of lithium-ion battery products. The detailed steps of the production process of lithium-ion batteries include positive electrode slurry drawing, negative electrode drawing slurry, positive electrode sheet, negative electrode sheet, steel shell assembly, liquid injection and testing, and packaging. At present, the core manufacturing processes of power lithium-ion batteries mainly include winding and lamination. The corresponding battery layout forms are mainly cylindrical and square, and soft packs. Cylindrical and square batteries are produced by recycling and winding processes, and soft pack batteries It is important to recycle the laminate process. The production and manufacturing of lithium-ion batteries have higher requirements for the function, accuracy, invariability and automation of the equipment. Take the preparation of electrode slurry in the production process of lithium-ion batteries as an example. The real-time front-end link of this link is also the most important link in the entire production process. What is the impact of the electrode slurry mixing process on the quality of the product More than 30%. It can be seen that each production link of the lithium-ion battery production process is closely related to the quality and safety of the product. Every link in the production process of lithium-ion batteries must be strictly and carefully managed, so as to promote the promotion of lithium-ion batteries. Product security function.
