| 英文摘要 | generally, the fast ion/electron transport and structural stability dominate the superiority in lithium-storage applications. in this work, porous carbon nanotubes decorated with nanosized cofe2o4 particles (p-cnts@cfo) have been rationally designed and synthesized by the assistance of supercritical carbon dioxide (scco(2)). when tested as anode materials for lithium-ion batteries, the p-cnts@cfo composite exhibits outstanding electrochemical behavior with high lithium-storage capacity (1077 mah g(-1) after 100 cycles) and rate capability (694 mah g(-1) at 3 a g(-1)). these outstanding electrochemical performances are attributed to the synergistic effect of porous p-cnts and nanosized cfo. compared to pristine cnts, the p-cnts with substantial pores in the tubes possess largely increased specific surface area and rich oxygen-containing functional groups. the porous structure can not only accommodate the volume change during lithiation/delithiation processes, but also provide bicontinuous electron/ion pathways and large electrode/electrolyte interface, which facilitate the ion diffusion kinetics, improving the rate performance. moreover, the cfo particles are bonded strongly to the p-cnts through metal-oxygen bridges, which facilitate the electron fast capture from p-cnts to cfo, and thus resulting in a high reversible capacity and excellent rate performance. overall, the porous p-cnts provide an efficient way for ion diffusion and continuous electron transport as anode materials.
