Lithium battery manufacturing process and analysis of lithium battery processing raw materials

Lithium battery manufacturing process: Lithium battery manufacturing process: the first, middle and back three processes, accounting for close to 35%/30%/35%. The critical processing process includes the stirring and coating stage of electrode production (front stage), the winding and liquid injection stage of cell synthesis (middle stage), and the packaging test stage of chemical packaging (back stage). The value amount (purchasing amount) accounts for approximately It is (35~40%):(30~35)%:(30~35)%. The difference mainly comes from the difference of equipment suppliers, the difference in the ratio of imported/domestic products, etc. The process flow is basically the same, and the proportion of value is deviated, but the overall proportion is in line with this ratio. Objectively speaking, the lithium battery processing 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 detailed process flow of lithium battery processing includes positive electrode drawing, negative drawing slurry, positive electrode sheet, negative electrode sheet, steel shell assembly, liquid injection and testing, and packaging. Analysis of raw materials for lithium battery processing: The critical raw materials for processing lithium batteries include lithium cobaltate, lithium nickelate, lithium manganate, three raw materials, lithium iron phosphate, and so on. The essential components of lithium battery processing materials include: positive electrode material, negative electrode material, separator, and electrolyte. It also includes other parts such as packaging. At present, the supply of raw materials for lithium batteries is sufficient, the output of some products is sufficient, and the competition is fierce, and its market prices continue to fall; however, the output of a small number of high-end products is insufficient, and the price of high-end raw materials is too high. Overall, the lithium battery industry is still hot. In fact, in the field of lithium battery cathode materials, any small technological innovation may set off a new round of market expansion. Chinese companies should strengthen the research and development of key technologies of cathode materials, gain an international leading position, and strengthen core competitiveness. Gain advantages in international competition. 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 materials generally have an oversupply situation in the low-end and middle-end products and the supply of high-end products exceeds demand. Lithium batteries are a new generation of green high-energy batteries with excellent performance and have become one of the focuses of high-tech development.
