Supercapacitive performance of hydrothermally grown ZnO on activated Carbon fiber cloth
Abstract
Activated carbon fiber cloth (ACC) with hydrothermally grown zinc oxide is investigated to see its supercapacitive performance as an electrode for supercapacitor. Here, we demonstrate how ZnO can be grown on ACC to enhance its surface area and thereby its capacitance and energy density. Electrochemical characterizations carried out on the samples revealed that ZnO/ACC showed less internal resistance and good conductivity as compared to ACC alone. It also exhibits high areal capacitance of 37.42mF/cm2, and high energy density of 3.33 μWh/cm2. In this regard, the fabricated ZnO/ACC electrode can be used for energy storage and microscale on-chip applications.
