Abstract:
Through the combined method of a low-temperature reflux and calcination, porous sandwich-like CNT@Fe3O4@C coaxial nanocables were cleverly constructed, which exhibited a favorable specific capacity of 724.8 mA h g-1 at 1000 mA g-1, a satisfying rate performance and admirable Coulombic efficiency (ca. 100%) for anodes of lithium-ion batteries. Due to the enlarged contact surface area, shortened Li+ diffusion distance, hierarchical porosity, reasonable structural design and good structural stability, the electrochemical performance of the CNT@Fe3O4@C nanocomposites was greatly enhanced in comparison with the traditional iron oxide anodes. So, it is a good candidate for anode materials with high performance.
