MoS 2 /MoO x nanostructures were grown on activated carbon cloth through a facile one‐step microwave‐assisted hydrothermal method. The growth of MoS 2 /MoO x on activated carbon cloth creates a unique structure that favors ion intercalation. The conductive activated carbon cloth, MoO 3− x , and monoclinic MoO 2 provide fast electron transport, whereas the MoS 2 nanosheets/MoO 3− x nanoparticles structure improves the capacitance. As a result, MoS 2 /MoO x ‐nanostructure‐decorated activated carbon cloth shows a high specific capacitance of 230 F g −1 at a scan rate of 5 mV s −1 with a low contact resistance of approximately 1.91 Ω. Moreover, the activated carbon cloth acts as a template for the growth of a perpendicular MoS 2 layer, which gives an excellent utilization rate of the active MoS 2 /MoO x material. We also demonstrate that the MoS 2 /MoO x /activated carbon cloth nanocomposite shows excellent electrochemical stability with retention up to 128 % after 1500 cycles. Finally, we show the use of a microwave‐assisted hydrothermal method for the synthesis of the MoS 2 /MoO x /activated carbon cloth nanocomposite as an alternative and clean route to improve the kinetics of the intercalation redox reaction.
