For the first time, WO2.72 nanowires were in-situ grown on carbon cloth by a simple solvothermal reaction. The nanowire WO2.72 /carbon cloth (NW WO2.72 /CC) electrode showed good electrochemical performance with specific capacitance ( C s ) reaching up to 398 F g - 1 at a current density of 2 A g - 1 . The capacitance of 240 F g - 1 was retained at a high current density of 16 A g - 1 . To further evaluate the energy storage performance, flexible asymmetric supercapacitors (FASCs) were fabricated using the activated carbon/carbon cloth (AC/CC) as negative electrode and NW WO2.72 /CC as positive electrode, respectively. The FASCs delivered a high energy density of 28 Wh kg - 1 at a power density of 745 W kg - 1 and 13 Wh kg - 1 even at a high power density of 22.5 kW kg - 1 . More impressively, 81％ of the specific capacitance of the FASCs was retained after 10,000 cycles, indicating excellent cycle stability. This work indicates the NW WO2.72 /CC holds a great potential for application in energy storage devices.
