dc.description.abstract | Sn-aminoclay (SnAC)-templated Fe3O4 nanocomposites (SnAC-Fe3O4) were prepared through a facile approach. The morphology and macro-architecture of the fabricated SnAC-Fe3O4 nanocomposites were characterized by different techniques. A constructed meso/macro-porous structure arising from the homogeneous dispersion of Fe3O4 NPs on the SnAC surface owing to inherent NH3+ functional groups provides new conductive channels for high-efficiency electron transport and ion diffusion. After annealing under argon (Ar) gas, most of SnAC layered structure can be converted to SnO2; this carbonization allows for formation of a protective shell preventing direct interaction of the inner SnO2 and Fe3O4 NPs with the electrolyte. Additionally, the post-annealing formation of Fe-O-C and Sn-O-C bonds enhances the connection of Fe3O4 NPs and SnAC, resulting in improved electrical conductivity, specific capacities, capacity retention, and long-term stability of the nanocomposites. Resultantly, electrochemical measurement exhibits high initial discharge/charge capacities of 980 mA h g(-1) and 830 mA h g(-1) at 100 mA g(-1) in the first cycle and maintains 710 mA h g(-1) after 100 cycles, which corresponds to a capacity retention of approximate to 89%. The cycling performance at 100 mA g(-1) is remarkably improved when compared with control SnAC. These outstanding results represent a new direction for development of anode materials without any binder or additive. | - |
