▎ 摘 要
Nanosheet-like tungsten diselenide (WSe2)/reduced graphene oxide (rGO) hybrid has been developed for the first time by facile one-step hydrothermal route for supercapacitor applications. Electrochemical measurements show that the WSe2/rGO-based supercapacitor electrode exhibits a maximum specific capacitance of 389 F g(-1) at 1 A g(-1) with capacitance retention of 98.7% after 3000 charge/discharge cycles at a high current density of 7 A g(-1), and delivered a energy density of 34.5Wh kg(-1) at 400 W kg(-1) and 22.4Wh kg(-1) at a high power density of 4000 W kg(-1).
