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.
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).
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 mixing process is the basic link in the electrode manufacturing process, and its process quality directly determines the development of subsequent process steps (e.g., coating process), which has an important impact on the comprehensive performance of lithium-ion battery .
This process is usually called drying process. There are many other steps in the lithium-ion battery manufacturing process that require the use of drying techniques, such as drying the raw material, drying the cell before the fluid is injected, and dehumidification in the air.
The electrode and cell manufacturing processes directly determine the comprehensive performance of lithium-ion batteries, with the specific manufacturing processes illustrated in Fig. 3. Fig. 3.
