CuCo₂S₄–MoS₂ nanocomposite: a novel electrode for high-performance supercapacitors

Abstract

Hydrothermal incorporation of an MoS 2 nanosheet onto ternary metal sulfide enhances the specific capacitance resulting in an asymmetric supercapacitor (CuCo 2 S 4 –MoS 2 //AC) with ultra-high energy density and power density as well as wide potential window.
