“…Many research efforts have already been devoted to enhancing the performance of graphite in LIBs. One strategy is the creation of new graphitic structures such as carbon nanotubes [ 9 ] and graphene [ 10 , 11 , 12 ]. The other approaches are manipulating graphite structure through doping non-metal elements (B, N, P, S) [ 13 , 14 , 15 , 16 ] or disordering graphite structure by various ball-milling techniques [ 17 , 18 , 19 , 20 , 21 ].…”

Graphite, with appealing features such as good stability, high electrical conductivity, and natural abundance, is still the main commercial anode material for lithium-ion batteries. The charge-discharge rate capability of graphite anodes is not significant for the development of mobile devices and electric vehicles. Therefore, the feasibility investigation of the rate capability enhancement of graphite by manipulating the structure is worthwhile and of interest. In this study, an effective ball-milling process has been set up by which graphite nanostructures with a high surface area are produced. An in-depth investigation into the effect of ball milling on graphite structure as well as electrochemical performance, particularly rate capability, is conducted. Here, we report that graphite nanoflakes with 350 m2 g−1 surface area deliver retained capacity of ~75 mAh g−1 at 10 C (1 C = 372 mA g−1). Finally, the Li+ surface-storage mechanism is recognised by associating the structural characteristics with electrochemical properties.
