Abstract

This paper describes the construction of hierarchical CuCo₂S₄ hollow spheres via a bubble-supported solvothermal method as electrodes for enhanced electrochemical performance. A high specific capacitance of 1137.5 F g⁻¹ has been obtained at 2 A g⁻¹ with exceptional rate capability (84.8% capacitance retention from 2 to 20 A g⁻¹) and good cycling stability (94.9% of the initial capacitance after 6000 cycles), making them promising electrodes for supercapacitors.
