Furthermore, in the ball milled mixture of 3Mg(NH2)2 and 8LiH, 7mass % of hydrogen is reversibly stored in the temperature from 140 to 220C, indicating one of the suitable hydrogen storage materials. In graphite containing a small amount of nanometer sized Fe (2 at.%), a large amount of hydrogen (7mass%) is chemisorbed by ball milling for 80 h under less than 1MPa of H2-gas pressure.

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.
