The application of battery-like electrode materials with complex hollow structures, huge surface areas, and good redox properties is an appealing approach towards the boosting performance of hybrid supercapacitors. This work proposes a facile strategy for the fabrication of copper-cobalt selenide hollow spheres (CCSe-HSs) as a new battery-type electrode for hybrid supercapacitors. Benefiting from the considerable electrical conductivity and rationally porous structures, this electrode exhibits a higher capacitance/capacity of 1775.4F g⁻¹/295.9 mAh g⁻¹ compared with copper-cobalt sulfide hollow spheres (CCS-HSs) and copper-cobalt oxide hollow spheres (CCO-HSs). Besides, an advanced device (CCSe-HSs//AC) constructs by combining copper-cobalt selenide hollow spheres (positive electrode) and activated carbon (AC, negative electrode). Our device reflects reasonable energy and power densities (53.86 …
