摘要

The global demand for energy is rising, prompting researchers to develop energy systems to meet the continuous energy requirements. To enhance the supercapacitor properties, perovskite nanomaterial was proven to be an efficient electrode material. The hydrothermal technique is useful for producing Ba-doped SrSnS3 nanomaterial and a pure SrSnS3 material. To analyze the crystal structure, surface area and texture of the materials being studied, scanning electron microscopy, Brunner–Emmet–Teller analysis, and X-ray diffraction were employed. The dopant (Ba-doped SrSnS3) nanomaterial exhibits a remarkable surface area with a value of 107 m2/g, while the pristine material has a value of 73.1 m2/g. Additionally, material tested through electrochemical characterizations in 3.0 M KOH, and the doped material demonstrated high specific capacitance of 1265 F/g (5 mV/s) and 1418 F/g (1 A/g) along with the power and energy density values were recorded 235 W/kg and 43 Wh/kg. Therefore, the dopant material Less resistance (Rs = 0.53 Ω) as observed from impedance measurements, suggesting the enhanced conductivity compared to the undoped material which boosted the ion movement and quick charge-storage technique demonstrated by the Ba-doped SrSnS3 nanomaterial indicated that the Ba-doped SrSnS3 could potentially be used in the forthcoming energy storage devices.
