The present study investigates MoS2@NiCoFe2O4 nanocomposites with different weight ratios and their influence on the electrochemical storage properties. The synthesized ferrite nanoparticles were combined with molybdenum disulfide (MoS2) nanosheets. To improve overall electrochemical storage performance, the prepared composite aimed to combine the high surface area and layered structure of MoS2 with the superior electrical conductivity and redox activity of NiCoFe2O4. The morphological, chemical, and physical characteristics of the produced nanocomposites were investigated and confirm the formation of the composites. NiCoFe2O4 nanoparticles were uniformly distributed over the MoS2 nanosheets, according to the morphological results, demonstrating a well-connected hybrid structure that facilitated ion diffusion and electron transport. The MoS2@NiCoFe2O4 nanocomposites electrochemical performance was assessed using half-cell studies and an asymmetric supercapacitor coin cell setup. After testing a variety of NiCoFe2O4 loadings, the sample with 10 % MoS2@NiCoFe2O4 showed the highest specific capacitance (84.6 F/g). Furthermore, self-discharge analysis confirmed strong voltage retention (0.89 V at 5000 s and 0.58 V after 20,000 s) and consistent performance across multiple cycles, underscoring the device’s excellent leakage resistance and durability. 98% of the capacitance was retained in 10000 repeated charge-discharge cycles.
