Reduced graphene oxide incorporated NiWO for high-performance energy storage.

Xing, Xuteng; Wang, Jihui

In this work, reduced graphene oxide (RGO) was incorporated into NiWO to obtain the RGO/NiWO composites by a facile hydrothermal method. The supercapacitive properties of these composites were studied by cyclic voltammetry and galvanostatic charge/discharge. It is surprised that the RGO/NiWO composite exhibits twice specific capacitance and better stability than NiWO. RGO acts as the conductive substrate for NiWO nanoparticles, which can not only inhibit the aggregations of the NiWO nanoparticles and RGO flakes to obtain the high specific surface area, but also improve the electrical conductivity to accelerate the charge transmission. Moreover, RGO is also an electrical double layer capacitor electrode material. Therefore, the RGO/NiWO composite is a good supercapacitive material.
