摘要

构建合适的纳米结构可以提供较大的比表面积来存储电荷。本文采用简单的水热法在活化的柚子皮衍生碳（ASPC-CoS@CoS2）上制备了三维层状CoS@CoS2复合电极膜。ASPC-CoS@CoS2在1.0 A g−1时的比电容为1160 F g−1。当组装成超级电容器（ASC: ASPC-CoS@CoS2//ASPC）时，ASC器件在364.5 W kg−1时实现了40.4 Wh kg−1的能量密度。这种性能的增强可归因于独特的层状多孔结构。

A 3D Layered ASPC-CoS@Cos2 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@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.
