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

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 ZnCoO nanorod arrays as ZnCoO@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 ZnCoO@NiO is used as an electrode material in a supercapacitor as it provides a high specific surface area (134.

Marigold micro-flower like NiCoO grown on flexible stainless-steel mesh as an electrode for supercapacitors.

Nanostructured NiCoO is a promising material for energy storage systems. Herein, we report the binder-free deposition of porous marigold micro-flower like NiCoO (PNCO) on the flexible stainless-steel mesh (FSSM) as (PNCO@FSSM) electrode by simple chemical bath deposition. The SEM and EDS analysis revealed the marigold micro-flowers like morphology of NiCoO and its elemental composition.
