The ball milling process is carried out for approximately 100–150 h to obtain uniform-sized fine powder. In high-energy ball milling, vacuum or a specific gaseous atmosphere is maintained inside the chamber. High-energy mills are classified into attrition ball mills, planetary ball mills, vibrating ball mills, and low-energy tumbling mills.

Herein, the chemistries of the binary Li 3 N·P 2 S 5 solid electrolytes, produced by ball milling, are studied in detail and reaction mechanisms are proposed. We show that less nitrogen is present in Li 3 N·P 2 S 5 solid electrolytes after ball milling than is expected due to the evolution of N 2 during the early stages of milling.

) without the ball milling time of 30 min, but the C total after ball milling for 60 min decreases slightly to about 1650 mAh/g (Li 4.4 C 6). This indicates that the ball milling for 60 min results in a decrease in the Li insertion capacity in the SWNT bundles, which are converted to the disordered/amorphous carbon by the increased ball milling.
