摘要

The uninterruptible and renewable energy is a major challenge for this current era. It is therefore important to fabricate new energy storage devices to attained uninterruptible energy. Supercapacitors (SCs) is a well-known storage device which has greater stability, high charge and discharge rates, good power, and energy density. For SCs, its electrode is known as a vital part and here, delafossite CuMnO2 and PANI nanohybrid electrode was fabricated via a simple hydrothermal technique. The generated hybrid material was characterized physically through various techniques like X-ray diffraction, Brunauer-Emmett-Teller, scanning electron microscopy, Fourier Transform infrared spectroscopy, and energy dispersive X-ray spectroscopy to confirm the crystallinity, high surface area, pore radius, morphological, functional group, and elemental composition respectively. The electrochemical investigation of CuMnO2/PANI nanocomposite was invested via three electrodes and asymmetric in 3 M KOH. The analysis showed a noteworthy Csp of 1411 F g−1 at 1 A g−1 and cyclic stability was 3000th cycles. The asymmetric device showed the ideal Csp of 146.82 F g−1 with a current density of 1 A g−1 and Ed of 90 Wh kg−1. SCs can also be utilized as dependable energy storage devices in urgent door-opening technologies for different air buses.
