In this field, sealing nails play a vital role in the power battery of vehicles, and the industrial piece needs strict quality inspection according to its visual appearance before application. However, many difficulties exist, such as the lack of defect samples, low visibility of defects, and irregular shapes in the defect detection of ...
There are various types of LiBs, depending on their constituent parts such as electrodes and their shapes. Since the optimal inspection method differs for each type, the choice of inspection method is very important in LiB quality control. For example, the three most common battery shapes are "cylindrical", "square", and "pouch (laminated)".
The Raman spectra of the anodes show contributions from three major components: graphite, carbon black, and fluorescence. The Raman spectra of the cycled anode exhibits two peaks at 1346 and 1582 cm-1, corresponding to the D and G bands, respectively.The D band corresponds to the presence of defects, and the G band …
