Vertically Aligned Carbon Nanotubes Grown on Graphene Paper as Electrodes in Lithium-Ion Batteries and Dye-Sensitized Solar Cells

Vertically aligned carbon nanotubes (VACNTs) are grown directly on a free‐standing graphene paper (GP). The desirable carrier transport ability of the VACNTs, good conductivity and mechanical properties of the GP, and strong bonding between the VACNTs and the GP endow the hybrid structure with superior performance when utilized as the electrodes of lithium‐ion batteries and dye‐sensitized solar cells.
