Abstract:

In this work, a scalable approach of preparing Co3O4/Co@N-C composite derived from metal organic frameworks (MOFs) is developed. After consecutive carbonization and oxidation of MOFs at different calcination temperatures, a series of nanocomposite consisting of Co3O4, conductive Co nanoparticles, and Nitrogen doped (N-doped) mesoporous carbon are obtained via in-situ polymerization strategy. When employed as anode materials for lithium-ion batteries (LIBs), the Crystalline-Co3O4/Co@N-C-700 (Cry-Co3O4/Co@N-C-700) electrode has shown high reversible specific capacity of 896.5 mAh g(-1) at 0.1 A g(-1), excellent rate capability of 376.2 mAh g(-1) at a large current density of 2 A g(-1), and robust longterm capacity retention rate of 96.0% at 0.2 A g(-1) after 50 cycles. Such superior lithium storage performance could be attributed to the unique porous structure which composed of well-dispersed Co(3)O(4)and conductive Co nanoparticles together with N-doped carbon skeleton. The unique structure can effectively improve the conductivity and act as a buffer medium to alleviate the volume change, which shows potential application for new energy storage materials.
