Herein, Agglomerated nanoflakes like perovskite lanthanum strontium manganite (La0.2Sr0.8MnO3) material fabricated using an essential-route solution combustion method followed by a post-annealing procedure. Finally screen printed electrode used as the materials for highperformance supercapacitors. The phase identification of Perovskite La0.2Sr0.8MnO3nanostructure was tested by X-ray diffractometer (XRD) and Fourier transform infrared (FT-IR) analysis confirms rhombohedral phase. Morphological studies were authenticated by Field emission scanning electron microscope (FE-SEM) showed that the well-developed agglomerated porous nanoflakes structured La0.2Sr0.8MnO3were prepared. Active surface area analysis was done by (BET) N2 physisorption technique. The electrochemical properties of the screen-printed materials were tested using a three-electrode system. As a result, the perovskite La0.2Sr0.8MnO3electrode materialshowed a higher Csp of 710F/g at a current density of 10 A/g within the potential range of -0.8 to 0.4 V in 1 M KOHelectrolyte solution. In addition, the perovskite La0.2Sr0.8MnO3electrode material delivered excellent cycling stability, retaining 72.05 % of its initial Csp after 5000 successive cyclic voltammetry (CV) cycles. These results show that the unique solution combustion synthesized perovskite La0.2Sr0.8MnO3electrode material has remarkable application potential and can achieve better characteristics for high-performance supercapacitors in energy storage applications. |
