▎ 摘　　要

NOVELTY - Preparation of graphene oxide three-dimensional self-assembled aerogel comprises ultrasonically mixing chemically synthesized graphene oxide in water for obtaining a graphene oxide suspension; adding sugar solution; ultrasonically dispersing for obtaining a mixed solution of sugar and graphene oxide; hydrothermally treating for obtaining graphene oxide three-dimensional self- assembled hydrogel; and lyophilizing the hydrogel for obtaining the aerogel. The synthesized graphene oxide three-dimensional self-assembled aerogel is pressed for preparing an electrode applied to a supercapacitor. USE - A preparation method of graphene oxide three-dimensional self-assembled aerogel used for energy storage, preferably supercapacitor (claimed) and battery. ADVANTAGE - The prepared material has excellent performances, such as high specific surface area and porous property, and has long cycle life when applied to an electrode material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene oxide three-dimensional self-assembled aerogel prepared by the above method.
