Meanwhile, a series of MoS_2-<i>x</i> nanostructures with sulfur vacancies have been successfully obtained in an Ar/H₂ mixed atmosphere at different annealing temperatures. The prepared materials were characterized by XRD, HR-TEM, Raman and XPS to identify their morphology and crystal properties. MoS_2-<i>x</i> assembled by interconnected nanosheets (MoS_2-<i>x</i> -700) provides a maximum specific capacitance of 143.12 F g^-1 at a current density of 1.0 A g^-1 with 87.1% of initial capacitance reserved after 5000 cycles.
