Abstract
Although particle shape plays a paramount role as much as particle size in the micronization and flotation stages used in the production of graphite material as LIB anode material, the relationship between graphite grinding and particle shape is almost non-existent. Therefore, this study aims to compare the particle shape of graphite particles at various grinding times with "tumbling" and "non-tumbling" mills, such as the most used laboratory ball mill and vibrating disc mill, by using DIA. According to both DIA and XRD, SEM, and stereo microscope results, VDM produced rounder particles in a shorter time than BM.
