The as-prepared CFs were investigated as anode materials for sodium ion batteries (SIBs). Remarkably, due to their weakly ordered turbostratic structure and a large interlayer spacing between graphene sheets, the CFs exhibit a dominant adsorption/insertion sodium storage mechanism that shows high reversibility. As a result, the CFs show excellent electrochemical performance, especially cycle stability (97.7% capacity retention ratio over 200 cycles). Reversible capacities of 233 and 82 mA h g-1 are obtained for the CFs at a current density of 0.05 A g-1 and even a high current density of 2 A g-1, respectively. The excellent cycle performance, high capacity and good rate capability make the CFs promising candidates for practical SIBs. © 2014 The Royal Society of Chemistry.||Source Title:||Journal of Materials Chemistry A||URI:||http://scholarbank.nus.edu.sg/handle/10635/86295||ISSN:||20507488||DOI:||10.1039/c3ta14806h|
