Abstract

Constructing suitable nanostructures can provide a large specific surface area for storing charge. A 3D layered CoS@CoS₂ composite electrode film grown on activated shaddock peel-derived carbon (ASPC-CoS@CoS₂) was prepared by a simple hydrothermal method in this work. The specific capacitance of the ASPC-CoS@CoS₂ is 1160 F g⁻¹ at 1.0 A g⁻¹. When assembled into a supercapacitor (ASC: ASPC-CoS@CoS₂//ASPC), the ASC device achieved an energy density of 40.4 Wh kg⁻¹ at 364.5 W kg⁻¹. This enhancement in performance can be ascribed to the unique layered porous structure.
