How many sections are the manufacturing process of lithium batteries divided into?

Lithium battery manufacturing process Objectively speaking, the lithium battery processing and manufacturing process is divided into three sections, one is pole piece production, the other is battery cell production, and the third is battery packaging. In the lithium battery processing technology, the production of pole pieces is the foundation and the production of battery cells is the core. The packaging of the battery is related to the quality of the finished lithium battery. The specific steps of the lithium battery processing process include positive electrode slurry drawing, negative electrode slurry drawing, positive electrode sheet, negative electrode sheet, steel shell assembly, liquid injection and testing, and packaging. At present, the core manufacturing processes of power lithium batteries mainly include winding and lamination. The corresponding battery structures are mainly cylindrical and square, and soft-packed. Cylindrical and square batteries are mainly processed by winding technology, while soft-packed batteries are The lamination process is important. The processing and manufacturing of lithium batteries have higher requirements for the performance, accuracy, stability and automation of the equipment. Take the preparation of electrode slurry in the lithium battery processing process as an example. This link is the foremost link in time and is also the most important link in the entire processing process. After all, the electrode slurry mixing and dispersion process has an impact on product quality greater than 30 %. It can be seen that each processing link in the lithium battery processing process is closely related to product quality and safety. Every link in the lithium battery processing process must be strictly and carefully managed, so as to improve the safety performance of lithium battery products. . Lithium battery processing process flow and control: raw material → raw material inspection → raw material pretreatment → ingredients → ingredient inspection → vacuum induction melting → rapid cooling ingot casting → semi-finished product inspection → heat treatment → coarse crushing → powder making → sieving → Post-processing→vacuum or nitrogen-filled packaging→finished product inspection→product.
