Abstract

Bir süperkapasitör elektrot malzemesi olarak, çiçek benzeri ZnCo2O4 nanotel (NW) dizileri hidrotermal yöntem kullanılarak doğrudan 3D-Ni köpük üzerinde büyütülmüştür. Elektrot malzemesinin yapısal ve morfolojik analizi XRD, FE-SEM ve EDS ile karakterize edilirken elektrokimyasal analizi ise CV, GCD ve EIS ile karakterize edilmiştir. Elektrot malzemesi, 0,5 mA cm-2 akım yoğunluğunda maksimum 1,01 F cm-2 'lik alansal kapasitans ile mükemmel bir elektrokimyasal performans göstermiştir. 2,000 şarj-deşarj döngüsünden sonra elektrot, başlangıçtaki alansal kapasitansın % 72'sine sahip olarak mükemmel bir döngü kararlılığı sergilemiştir.

Investigation of Flower-like ZnCo2O4 Nanowire Arrays Growth on 3D-Ni Foam as Supercapacitor Electrode Material

Abstract

As a supercapacitor electrode material, flower-like ZnCo2O4 nanowire (NW) arrays were directly grown on 3D-Ni foam using the hydrothermal method. Structural and morphological analysis of the electrode material was characterized by XRD, FE-SEM, and EDS, while its electrochemical analysis was characterized by CV, GCD, and EIS. The electrode material demonstrated excellent electrochemical performance with a maximum areal capacitance of 1.01 F cm-2 at a current density of 0.5 mA cm-2. After 2.000 charge-discharge cycles, the electrode showed excellent cycle stability, having 72% of the initial areal capacitance.
