The specific steps in the lithium-ion battery production process include positive electrode slurry drawing, negative electrode slurry drawing, positive electrode sheet, negative electrode sheet, steel shell assembly, electrolyte injection and testing, and packaging.
Currently, there are two main manufacturing processes for power lithium-ion battery cells: winding and stacking. The corresponding battery structures are mainly cylindrical, prismatic, and pouch. Cylindrical and prismatic batteries are mainly produced using the winding process, while pouch batteries are mainly produced using the stacking process.
The production of lithium-ion batteries places high demands on the performance, precision, stability, and automation level of equipment. Taking the preparation of electrode slurry in the lithium-ion battery production process as an example, this step, being the very beginning, is also the most crucial step in the entire production process, as the mixing and dispersion process of the electrode slurry has a greater than 30% impact on the quality of the product.
It is evident that every stage of the lithium-ion battery production process is closely related to product quality and safety. Each stage of lithium-ion battery production must be managed rigorously and meticulously in order to improve the safety performance of lithium-ion battery products.
