  "abstract": "The growing need for sustainable and eco-friendly energy solutions has intensified the efforts to develop advanced electrode materials with superior electrochemical traits. In this study, we synthesized Ni₉S₈ (NS), and its carbon nanotube (CNT) based composites containing 3, 6, and 9% CNTs (NS-3, NS-6, and NS-9) for supercapacitor applications. NS exhibited an initial plate-like morphology, which transformed into a CNT-entangled structure in composites. NS-6 showed an increased surface area of 61.72 m² g⁻¹, reflecting the coexistence of both micro and mesopores. Cyclic voltammetry revealed well-defined redox peaks across multiple scans, signifying a hybrid charge storage behavior, as validated through Dunn's model analysis. Among all composites, NS-6 showed the best electrochemical performance, achieving a specific capacity of 1382.47 C g⁻¹ at 2.0 A g⁻¹ and excellent cyclic stability with 95.5% retention after 10 000 cycles. The composite also presented enhanced ionic conductivity (4.4 × 10⁻² S cm⁻¹), reduced charge transfer resistance (2.51 Ω), and a diffusion coefficient of 7.48 × 10⁻¹¹ cm² s⁻¹. Based on these optimized results for NS-6, an asymmetric device was assembled, delivering 301.11 C g⁻¹, an energy density of 50.18 Wh kg⁻¹, and a power density of 705.88 W kg⁻¹. These results highlight NS-6 as a leading contender for efficient electrode materials for future energy solutions.",
