The major use of the conventional ball milling is to fracture the particles and to reduce the size, which is different from the newly established high energy ball milling (HEBM) method. In this new method a magnet is placed close to the cell to apply a strong magnetic pulling force on the magnetic milling balls, and therefore the impact energy is much higher than the conventional ball milling
