Production steps in lithium-ion battery cell manufacturing summarizing electrode manufacturing, cell assembly and cell finishing (formation) based on prismatic cell format. Electrode manufacturing starts with the reception of the materials in a dry room (environment with controlled humidity, temperature, and pressure).
Conventional processing of a lithium-ion battery cell consists of three steps: (1) electrode manufacturing, (2) cell assembly, and (3) cell finishing (formation) [8, 10]. Although there are different cell formats, such as prismatic, cylindrical and pouch cells, manufacturing of these cells is similar but differs in the cell assembly step.
The manufacture of the lithium-ion battery cell comprises the three main process steps of electrode manufacturing, cell assembly and cell finishing. The electrode manufacturing and cell finishing process steps are largely independent of the cell type, while cell assembly distinguishes between pouch and cylindrical cells as well as prismatic cells.
The manufacturing process for the Li-Ion battery can be divided roughly into the five major processes: 1. Mixing, kneading, coating, pressing, and slitting processes of the positive electrode and negative electrode materials. 2. Winding process of the positive electrode, negative electrode, and separator.
There is no continuous automation technology, making it difficult for cell manufacturers to transform lithium-ion cell manufacturing into a mass-production process. Overall, the current structures lead to considerable disparities in the quality of the end product.
The products produced during this time are sorted according to the severity of the error. In summary, the quality of the production of a lithium-ion battery cell is ensured by monitoring numerous parameters along the process chain.
