Nanocrystalline V2O5 particles were successfully entrapped by graphene nanoribbons (GNRs) derived from unzipped carbon nanotubes. The electrical conductivity of V2O5 nanoparticles was enhanced after introducing the GNRs. The 3-dimensional conductive framework in the composites plays a significant role in improving the rate performance and cyclability of the material when used as a cathode in lithium-ion batteries. By tailoring the mass ratio between the GNRs and the V2O5 nanoparticles, the… CONTINUE READING
