Wide Facets ZnCo₂O₄ Nanosheets for High Electrochemical Supercapacitor Performances

Abstract

ZnCo 2 O 4 nanosheets show excellent supercapacitive performance due to their well-developed and uniform architecture. The unique nanosheets with wide facets deliver outstanding electrochemical supercapacitor performance. As a result, the catalyst exhibits a specific capacitance of 700 F/g at a current density of 1 A/g. Interestingly, the material also shows outstanding cycling stability and loses only 2.75% even after 5000 cycles. The study confirms that ZnCo 2 O 4 based materials can be applied in high-energy as well as high-power density applications (energy storage, electric vehicles, and flexible electronic devices) due to their excellent morphology, wide facets, outstanding stability, and capacitance.
