| description | This study reports on the synthesis and characterization of a novel electrode material for supercapacitor applications based on a clustered heterostructure of indium sulfide (In<sub>2</sub>S<sub>3</sub>) and single-walled carbon nanotubes (SWCNTs). The In<sub>2</sub>S<sub>3</sub>-SWCNT (INSC) sample was prepared using the facile successive ionic layer adsorption and reaction (SILAR) method and demonstrated a higher specific capacitance (258 Fg<sup>−1</sup> at 1 Ag<sup>−1</sup>) compared to the bare indium sulfide (In<sub>2</sub>S<sub>3</sub>) electrode. The enhanced electrochemical performance is attributed to the synergistic effect between the In<sub>2</sub>S<sub>3</sub> and SWCNTs, which improves electron transportation, catalytic nature, and specific capacitance. Moreover, the cyclic stability of the INSC electrode was significantly improved, retaining 96.8% of the initial capacitance after 3000 cycles. The high voltage holding capacity and high cyclic efficiency of the fabricated INSC-based supercapacitor devices suggest their potential for next-generation energy storage devices. Additionally, the INSC electrode-based supercapacitor devices exhibit excellent flexibility and bendability, retaining similar performance even at a bending angle of 180°, making them suitable for flexible energy storage applications. |
