| 英文摘要 | In this work, we present a facile strategy for the synthesis of well-structured transition metal oxides based composites by the decomposition of nitrate and polyvinylpyrrolidone (PVP) followed by simple oxidation at a low temperature and using them as high performance materials for reversible lithium storage. As proofs of this simple strategy, three kinds of TMOs, namely NiO, Fe2O3 and Co3O4, based composites have been prepared with this simple strategy. The morphology and structure analyses indicate that TMOs nanoparticles with a size of 10 nm are tightly coated by the in situ formed graphene-like carbon shell and evenly dispersed in the microsized nitrogen-doped carbon sheets (C@TMOs@NCSs) derived from the PVP. As lithium storage materials, the as-prepared C@NiO@NCSs composites show excellent electrochemical performances in terms of cycle stability (651 mAh g(-1) after 1500 cycles at 1 Ag-1 and 518mAh g(-1) after 1400 cycles at 2 A g(-1)) and rate capability (400 mAh g(-1) at 4 A g(-1)). Such superior electrochemical performance is attributed the well-structured composites with features of tight carbon coating layer, evenly dispersed TMOs nanoparticles and robust carbon supports.
