A 3D Layered ASPC‐CoS@Cos<sub>2</sub> Composite Electrode Film via Simple Hydrothermal Method for High‐Performance Supercapacitors
Constructing suitable nanostructures can provide a large specific surface area for storing charge. A 3D layered CoS@CoS 2 composite electrode film grown on activated shaddock peel‐derived carbon (ASPC‐CoS@CoS 2 ) was prepared by a simple hydrothermal method in this work. The specific capacitance of the ASPC‐CoS@CoS 2 is 1160 F g −1 at 1.0 A g −1 . When assembled into a supercapacitor (ASC: ASPC‐CoS@CoS 2 //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.
