Hybrid type supercapacitors store electrical energy through a combination of
double layer charging and Faradic processes. The active electrode material plays a pivotal
role on the performance of these supercapacitors. In this article, the use of different metal oxide-
carbon nanomaterial-conducting polymer ternary nanocomposites as working electrode
materials in hybrid supercapacitors is presented.
Keywords: Composites, conducting polymers, electrode material, graphene, metal
oxide, supercapacitors, ternary.
