Abstract:

Perovskite oxides represent an important class of functional materials with the general formula ABX₃. Their distinctive crystal framework offers high electrical conductivity, structural robustness and tunable properties, making them attractive for supercapacitors (SC_s). In this work, SrMoO₃/PANI composite was prepared through a hydrazine-assisted wet-chemical route, followed by heat treatment in a muffle furnace and explored as an innovative supercapacitor electrode. This straightforward and low-cost method enables the successful formation of a phase for pure SrMoO₃. The incorporation of PANI into SrMoO₃ enhances the overall properties of the composite , as analyzed via different characterization techniques. The electrochemical study shows a superior specific capacitance (C_s) of 675.5 F g⁻¹, power density (P_d) of 1601.2 W kg⁻¹ and an energy density (E_d) of 37.9 Wh kg⁻¹. These improvements are due to the synergistic interplay between the perovskite phase and the conducting polymer, leading to enhanced charge mobility and ion diffusion. The excellent electrical properties and structural stability ofperovskite-based materials such as SrMoO₃ are promising candidates for supercapacitor electrodes. This study reports a novel, scalable and economical approach for fabricating SrMoO₃-based composites, underscoring their applicability for practical high-performance energy storage applications.
