SiC/C composite mesoporous nanotubes as anode material for high-performance lithium-ion batteries

The demand for high energy-storage lithium-ion batteries (LIBs) encourages the development of novel anode materials to substitute graphite. Herein, novel SiC/C composite mesoporous nanotubes derived from resorcinol-formaldehyde resin/silica composites were designed and fabricated towards LIBs anode materials, which contained 31 wt% amorphous C and 69 wt% cubic beta-SiC. The electrochemical measurements showed that the SiC/C electrode delivered a high reversible capacity of 527 mAh g(-1) after 250 cycles at a current density of 0.1 A g(-1), higher than the theoretical capacity of graphite, implying that SiC nanomaterials are potential anode candidate for LIBs.
