Abstract

In the last few years, perovskites have been getting a lot of attention towards energy storage devices. Herein, to increase the energy density of supercapacitors, solgel technique was employed to fabricate sandwich like DyMnO₃ nanostructure. The DyMnO₃ structural, morphological, and elemental analysis as well as its electrochemical characteristics, are meticulously investigated via different techniques. Due to the large surface area (97.9 m²/g) of the DyMnO₃ resulted in a high specific capacitance of 1929 F/g, while it has a high energy density of 72.3 Wh/kg at a scan rate of 5 mV/s via cyclic voltammogram. This is due to the fact that these devices are more durable, with the DyMnO₃ retaining 95 % of their particular capacitance after 10,000 cycles.
