Abstract

For the purpose of stable performance in energy storage systems, a new hollow nanostructure of sea-sponge-C/SiC@SiC/C (SCS/SiC@SiC/C) has been successfully fabricated by the SCS/SiC nanospheres coated with SiC/C shells through an in situ reduction process. Based on SCSs and the carbon shells, the stable hollow structures of SCS/SiC@SiC/C can contain large proportion of active SiC layers, which are adhered to both SCSs and the inner surfaces of carbon shells. Such nanostructured anode enables an excellent cycling stability with a capacity of 612 mAh g-1 at a current density of 0.5 A/g after 1,800 cycles, achieving an excellent stable Li+-storage capability.
