Graphene Oxide Annealing Procedures for Graphene-Based Supercapacitors

Abstract

Graphene is an excellent material for energy storage devices such as supercapacitors. Graphene can be deposited onto a substrate for device construction in multiple ways. One method is to deposit graphene oxide (GO) onto a surface and reduce it, resulting in reduced graphene oxide (rGO). There are many methods of reduction possible; this report discusses thermal reduction. Our goal is to outline a procedure for the thermal reduction of GO to optimize the performance of supercapacitors. We also demonstrate thermally assisted ionic liquid electrolyte wetting of the electrodes, as well as our initial attempts at making high operating temperature supercapacitors.
