“…Nematzadeh et al also synthesized the hardly oxidized silicene nanosheets as the electrodes of Li metal half-cells by using the same method. 44 However, the battery performance was much worse than that reported in the previous work, 43 which might be ascribed to the different binders and solvents for the electrolyte. Compared with the results from ref.…”

“…[15][16][17] The lattice constant of multilayer silicene is larger, and its theoretical capacity can reach about three times that of graphite. 18,19 In order to further improve the electrochemical properties of silicene materials, various modification methods have been widely used, especially light atom doping, which has been widely studied. For example, doping with B atoms can significantly improve the conductivity and theoretical lithium capacity of graphene and silicene anode materials.…”

In this study, silicene nanosheets (SNs) were synthesized using molten salt chemical exfoliation. Polythiophene (PTh) and SNs/PTh nanocomposites were prepared through an in-situ chemical oxidative polymerization method. Raman spectroscopy confirmed the formation of SNs, PTh, and various SNs/PTh nanocomposites at different ratios. X-ray diffraction (XRD) analysis verified the presence of crystalline SNs, the amorphous nature of PTh, and the combination of crystalline SNs with amorphous PTh in the nanocomposites. Field-emission scanning electron microscopy (FESEM) revealed the morphology of silicene sheets and the distribution of PTh granular globes and flakes in the SNs/PTh nanocomposites. Transmission electron microscopy (TEM) showed transparent and reduced-stacking SNs, as well as aggregated PTh flakes and evenly distributed PTh flakes over the SNs surface in the nanocomposites. Electrochemical tests indicated that SNs/PTh nanocomposites exhibited higher specific capacitance, energy density, and stable cycling performance compared to individual SNs and PTh. Cyclic voltammetry (CV) measurements showed that the best performing supercapacitor electrode, SNs/PTh-67 nanocomposite displayed a specific capacitance of 276.25 F/g at a scan rate of 5 mV/s and delivered an energy density of 13.8 Wh/kg. The SNs/PTh-67 nanocomposite also exhibited excellent cycling stability with a capacitance retention of 85.9% after 2000 consecutive charge–discharge cycles at a current density of 4 A/g. This study demonstrates the potential of SNs/PTh-67 nanocomposite as a stable and high-performance electrode material for supercapacitors.
