Abstract

Graphene/carbon nanotube/silicon nanotube (GN/CNT/Si) ternary composites were synthesized by a expedient hydrothermal method. The as-prepared GN/CNT/Si composite shows three dimensional architectural structure, in which Si particles are uniformly distributed among the wrinkled graphene thin sheets and twisted carbon nanotubes. The movement of electrons and lithium ions can be accelerated through the interconnection of graphene sheets and carbon nanotubes, optimizing their transport efficiency. Electrochemical tests have shown that GN/CNT/Si composite can retain a specific discharge capacity of 760 mAh/g after 100 cycles at 0.1C. The electrochemical properties of the GN/CNT/Si composite are superior to the pristine silicon powder and graphene-nanosilicon composite.
