Currently, the advancement in energy storage technology is a worldwide-based vital challenge, so researchers focused on the development and design of promising electrode materials for energy storage equipment. Perovskite oxide and transition metal selenide nanocomposites can achieve better cycle stability, efficient electric conductivity, high capacity, excellent redox reaction, and inattentive flexibility as electrode materials for energy storage devices and supercapacitor applications. Herein, we present the designed, fabricated, and electrochemical properties of MnSe-supported SrZrO 3 nanocomposite via the Pechini method that exhibited more efficient capacitive performance than pristine SrZrO 3 and MnSe. The result of electrochemical testing indicates that the SrZrO 3 –MnSe nanocomposite electrode possessed a battery-type pseudocapacitive nature and displayed a boosted specific capacitance of 1204 Fg-1 at a 5 mV/s scan rate in aqueous 1 M KOH solution under a three-electrode setup and maintained 95.2% retention after 3000th cycles. It also showed a higher electrochemical active surface area (1680.5 cm2), higher energy density (40 Wh/Kg), long-term cyclic stability performance, and enhanced rate capability compared to other prepared products. As a result, these findings have shown that SrZrO 3 –MnSe nanocomposite can be considered as potential electrode materials and might have emerging applications in commercial products for energy storage devices and supercapacitors.
