Pieces of lithium metal, h-BN and graphite powders, with a 1/1.1/1.1 M ratio, were ball-milled using a vibratory ball mill machine and annealed at 700 °C for 2 h under argon atmosphere. After milling, Li-GICs and a small amount of Li 3 N were produced, as well as some unreacted and defective Li metal and h-BN.

Therefore, graphite has been previously treated with a ball mill for different times (1–16 h) to enhance its lubricating action. We checked an improvement in stiffness, yielding strength, thermal stability, and, in particularly, wear resistance that increased by 65% with respect to that of polyethylene (PE).

Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.

The Description and Function of Ball Mill： Ball mill is the key equipment for recrushing the materials after they are primarily crushed. Ball mill is widely used for the dry type or wet type grinding of all kinds of ores and other grindable materials in cement, silicate product, new building material, refractory, fertilizer, black and non-ferrous metals and glass ceramic industry.
