Graphene and Polymer Composites for Supercapacitor Applications: a Review
Abstract Supercapacitors, as one of the energy storage devices, exhibit ultrahigh capacitance, high power 924 density, and long cycle.High specific surface area, mechanical and chemical stability, and low cost are often required for supercapacitor materials.Graphene, as a new emerging carbon material, has attracted a lot of attention in energy stor
