Abstract: This article summarized the research process of graphene supercapacitors, including graphene electrode materials, modification of graphene, compounding with pseudo-capacitance electrode, structure design, choosing of electrolytes, and flexible supercapacitors. In practial manufacturers and tis application were introduced. Future applications of supercapacitors will not be limited to consumer electronics, but extend to the field of hybrid electric vehicles.

Key words: graphene, supercapacitor, solar cell, new energy, automobile
