Natural Graphite Grinding
Purification process of natural graphite as anode for Li ...
Grinding the natural graphite before or after purification had no significant effect on electrochemical performance at low currents. However, grinding to a very small particle size before purification permitted optimization of the size distribution of the particles, which gives rise to a more homogenous electrode.

Ultrasonic Grinding of Natural Graphite - NASA/ADS
FINE grinding of graphite is usually carried out in a mortar or in a ball mill. The reduction of the particle size proceeds rather slowly due to the lubricating action of the grain surfaces, and the ground crystals contain various kinds of lattice imperfections including stacking faults-the extent of the imperfections being subject to the period and method of grinding.
