3D cuboidal vanadium diselenide embedded reduced graphene oxide hybrid structures with enhanced supercapacitor properties

Hydrothermal synthesis of VSe₂/reduced graphene oxide (RGO) has been reported and its supercapacitor performance was evaluated in a typical CR2032 coin cell setup. A specific capacitance of 680 F g⁻¹and an ultra-high energy density of 212 W h kg⁻¹were achieved.
