摘要

Recently, two-dimensional materials have been extensively utilized in fabricating supercapacitors (SCs). Particularly, the layered materials have gained much attention among researchers and engineers owing to their unique morphological diversity, larger area, higher conductivity, and splendid charge storage capability. In this perspective, the present work affords the synthesis of a hybrid MoS2/GO/h-BN nanocomposite (NC) electrode via a hydrothermal-assisted liquid-phase exfoliation process. The synthesized NCs were examined through several physico-chemical and electrochemical techniques. Concurrently, the electrochemical investigation suggests that the designed electrode renders a maximum specific capacitance of 329 Fg−1 at a current density of 0.5 Ag−1. However, the fabricated asymmetric supercapacitor device assembled with MoS2/GO/h-BN as the positive electrode and activated carbon (AC) as the negative electrode (MoS2/GO/h-BN//AC), which displays an energy density (Ed) of 36.5 Wh kg−1 and the power density (Pd) of 1043 W kg−1. Besides, it exhibits an excellent capacitive retention of 94.0% even after 10,000 continuous charge/discharge cycles.
