Enhanced electrochemical performance of vanadium dioxide (B) nanoflowers with graphene nanoribbons support

Abstract

Specific VO2 (B) nanoflowers and their composite hybridized with graphene nanoribbons (GNRs) are prepared using a moderate H2C2O4 reductant to reduce V2O5 with the molar ratio of H2C2O4 : V2O5 as 3 : 1. The discharge specific capacities and the cycling stabilities of the VO2 (B) cathode material for lithium-ion batteries can be improved by graphenes support. In particular, GNRs support can improve the dispersibility and the electrical conductivity of the VO2 (B) nanoflowers. Thus, VO2 (B)/GNRs (32.2 wt%) composite exhibits excellent electrochemical performance with the high specific capacity of 471.5 mA h g−1 and the preferable cycling stability.
