摘要

Binder-free (BF) homogeneous Molybdenum disulfide (MoS2) nanosheets showing an average crystallite size of 34.59 nm, are deposited on nickel foam (NiF) by chemical vapor deposition process. The MoS2/NiF electrode exhibited a surface area of 109 m2/g, specific capacitance of 2726 F/g at 5 mV/s, charge transfer resistance of 2.36 Ω, and diffusion resistance of 1.16 for 10,000 cycles. The electrode is presented cyclic stability and Coulombic efficiency of 83% and 95% after 10,000 cycles. The capacitive contributions are remained lower than diffusion across scan rates 5–140 mV/s. The assembled device delivers capacitance of 191 F/g at 1.5 A/g, with maximum energy density of 68Wh/kg at minimum power density of 1200 W/kg. The theoretical model simulations is confirmed that the synthesized electrode showed excellent electrochemical performance due to combined current contributions of capacitive and diffusion controlled processes. Therefore, the MoS2/NiF electrodes are suitable for hybrid supercapacitive performance.
