Graphene is one of the most interesting matrix materials for constructing flexible supercapacitor electrodes due to its high electrical conductivity, high specific surface area, excellent mechanical properties, and ease of assembly. In this paper, the preparation and properties of graphene-based(GB) flexible electrodes based on heat transfer and convection are mainly studied. This paper firstly introduces the preparation methods of graphene materials and the research progress of flexible electrodes, and discusses the current application environment of GB flexible electrodes. In this paper, graphene oxide (GO) hydrogel was used as raw material, and water-soluble manganese salts (anhydrous manganese sulfate and manganese acetate) were used as manganese source, and graphite oxide was prepared on flexible conductive substrate (titanium foil) by doctor blade coating method. The olefin-Mn2+ composite film is then used for laser sintering. The high temperature at the laser focus reduces GO to reduced graphene oxide (RGO) and simultaneously cracks the manganese salt into manganese dioxide at high temperature, thereby fabricating a flexible composite electrode.
