Effect of extended ball milling on graphite

However, no data was presented on the mass loss in an inert atmosphere during heating and the difference may simply be attributed to adsorption of oxygen as graphite is substantially more reactive towards oxygen after milling [7], [8], [31]. Increased intercalation of lithium ions has also been reported for milled graphite [7], [32].

In-plane defects produced by ball-milling of expanded graphite

During the milling process (up to 100 h), the crystallite size (L c) of EG decreases gradually from 15.4 to 11.3 nm. Compared with most of natural graphite, this L c decrease degree of EG is far lower. In the EG after ball-milling for 100 h, plenty of in-plane defects are produced, which rarely occur in most of ball-milled natural graphite.
