2.1. State-of-the-Art Manufacturing 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].
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 presence of pits, R-angle injuries, hard printing, and other defects on the end face of lithium battery shells severely affects the production safety and usage safety of lithium battery products. In this study, we propose an effective defect-detection model, called Sim-YOLOv5s, for lithium battery steel shells.
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.
Considering the fact that LIB is prone to be short-circuited, shell material with lower strength is recommend to select such as material #1 and #2. It is indicated that the high strength materials are not suitable for all batteries, and the selection of the shell material should be matched with the safety of the battery. Table 3.
