Abstract
- Supercapacitors have been extensively studied due to their advantages of fast-charging and discharging, high-power density, long-cycling life, low cost, etc. Exploring novel nanomaterial schemes for high-performance electrode materials is of great significance. Herein, a strategy to combine vertical graphene (VG) with MoO<subscript>3</subscript> nanosheets to form a composite VG/MoO<subscript>3</subscript> nanostructure is proposed. VGs as transition layers supply rich active sites for the growth of MoO<subscript>3</subscript> nanosheets with increasing specific surface areas. The VG transition layer further improves the electric contact and adhesion of the MoO<subscript>3</subscript> electrode, simultaneously stabilizing its volume and crystal structure during repeated redox reactions. Thus, the prepared VG/MoO<subscript>3</subscript> nanosheets have been demonstrated to exhibit excellent electrochemical properties, such as high reversible capacitance, better cycling performance, and high-rate capability.
