Abstract
The urgent demand for efficient and sustainable energy storage systems presents a critical challenge in the development of high-performance electrode materials . This study addresses this gap by synthesizing a novel g-C 3 N 4 @SnS 2 heterostructure aimed at advancing supercapacitor technology. The engineered composite demonstrated a superior specific capacitance of 787 F/g at 0.8 A/g and a notable energy density of 56.8 Wh/kg, surpassing the performance of its individual components. Electrochemical impedance spectroscopy (EIS) revealed a reduction in charge transfer resistance, indicating enhanced ion transport and improved conductivity within the composite. The promising electrochemical characteristics, coupled with structural integrity and stability, position g-C 3 N 4 @SnS 2 as a viable candidate for industrial applications in next-generation energy storage devices.
