| 英文摘要 | Recently, Fe3O4-based materials have been widely studied as anodes in lithium-ion batteries (LIBs) because of the large theoretical capacity (924 mAh g(-1)) and environmental benignity. Unfortunately, these materials suffer from the low practical capacity and poor cycling stability. Herein, we developed a simple "soft-templating" approach to fabricate multiple Fe3O4 nanoparticles-embedded and N-doped hierarchically porous carbon nanospheres (Fe3O4@N-HPCNs) as anodes for LIBs by utilizing the self-assembly among polystyrene-b-poly(acrylic acid), cetyltrimethylammonium bromide, and hydrophobic Fe3O4 nanoparticles in oil/water system. The resultant Fe3O4@N-HPCNs present a well-defined spherical morphology, high specific surface area, and unique dual-mesoporous core structures with multiple Fe3O4 nanoparticles in the large-mesopore channels. More importantly, the Fe3O4@N-HPCNs anode exhibits high reversible specific capacities of 1240 mAh g(-1) (after 100 cycles at 0.1 A g(-1)) and 581 mAh g(-1) (after 400 cycles at 1 A g(-1)). Even at 10 A g(-1), a specific capacity of ca. 290 mAh g(-1) is still retained, indicating its excellent rate capability. Therefore, such a "soft-templating" approach is expected to provide us a new pathway to design and prepare other nanoparticles@porous carbon anodes for LIBs. |
