In terms of defect detection in battery shells, the major relevant studies have mainly focused on photovoltaic cells or button cells, whereas there are few studies on cylindrical lithium batteries and defects of the end face of the battery shell.
In the past, manual visual inspection was the main detection method chosen by battery manufacturers to detect defects in battery shells.
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.
