摘要 Nitrogen was doped into chemically-reduced mesocarbon microbead oxide (CR-MCMBO) through simple annealing in ammonia at 800 _C, and the Li-ion storage properties of the prepared nitrogen-doped CR-MCMBO (NR-MCMBO) was studied. It was found that NR-MCMBO shows a highly reversible capacity of 762 mAh g_1 at 20 mA g_1 during the first charge process, which is much higher than that of the pristine MCMB (289 mAh g_1), and the specific capacity of NR-MCMBO still had a value of 535 mAh g_1 after 200 cycles. When the current density reaches 1000 mA g_1, the specific capacity of NR-MCMBO is 388 mAh g_1. The high reversible capacity of NR-MCMBO is attributed to the high amount of pyridinic nitrogen and the large number of defects induced by oxidation and nitrogen-doping. Moreover, the open pores constituted by graphene-like nanoplatelets on the spherical NR-MCMBO surface
facilitate the diffusion of Li ions.
 
; Nitrogen was doped into chemically-reduced mesocarbon microbead oxide (CR-MCMBO) through simple annealing in ammonia at 800 degrees C, and the Li-ion storage properties of the prepared nitrogen-doped CR-MCMBO (NR-MCMBO) was studied. It was found that NR-MCMBO shows a highly reversible capacity of 762 mAh g(-1) at 20 mA g(-1) during the first charge process, which is much higher than that of the pristine MCMB (289 mAh g(-1)), and the specific capacity of NR-MCMBO still had a value of 535 mAh g(-1) after 200 cycles. When the current density reaches 1000 mA g(-1), the specific capacity of NR-MCMBO is 388 mAh g(-1). The high reversible capacity of NR-MCMBO is attributed to the high amount of pyridinic nitrogen and the large number of defects induced by oxidation and nitrogen-doping. Moreover, the open pores constituted by graphene-like nanoplatelets on the spherical NR-MCMBO surface facilitate the diffusion of Li ions. Crown Copyright (C) 2011 Published by Elsevier Ltd.
