Structure-engineering of core-shell ZnCo₂O₄@NiO composites for high-performance asymmetric supercapacitors.

ABSTRACT: The implementation of a structure-designed strategy to construct hierarchical architectures of multicomponent metal oxide-based electrode materials for energy storage devices is in the limelight. Herein, we report NiO nanoflakes impregnated on ZnCo₂O₄ nanorod arrays as ZnCo₂O₄@NiO core-shell structures on a flexible stainless-steel mesh substrate, fabricated by a simple, cost-effective and environmentally friendly reflux condensation method. The core-shell structure of ZnCo₂O₄@NiO is used as an electrode material in a supercapacitor as it provides a high specific surface area (134.79 m² g^-1) offering high electroactive sites for a redox reaction, reduces the electron and ion diffusion path, and promotes
