Nanodiamond-derived carbon nano-onions (N-CNOs) were prepared by annealing of nanodiamonds at 1650 �C under flow of helium. The morphology and structure of N-CNOs were investigated by high-resolution transmission electron microscopy (HRTEM), X-ray diffraction, Raman spectroscopy and BET nitrogen adsorption. Due to their smaller size and number of surface defects, they exhibit higher surface area (520 m2/g) and mesoporosity. Due to their smaller size, high surface area and number of surface defects, these N-CNOs exhibit high capacity and stable cycling performance as anode materials for lithium-ion batteries at slower (C/10) and higher (C) charge-discharge rates compared with that of mesocarbon microbead (MCMB) graphite particles.
