▎ 摘　　要

NOVELTY - Preparation of nitrogen- and sulfur-doped graphene-graphene nanobelts aerogel involves preparing graphene oxide nanobelts, preparing graphene oxide, mixing graphene oxide nanobelt and graphene oxide, adding deionized water, ultrasonically processing, obtaining 2 mg/ml mixture (I), adding pyrrole and thiophene to mixture (I), hydrothermally processing at 165-180 degrees C for 3-5 hours, obtaining hydrogel, placing hydrogel in 2 M potassium nitrate solution, further carrying out hydrothermal reaction at 120-130 degrees C for 2-3 hours, cooling to room temperature, filtering, washing, freeze-drying and thermally cracking at 1050-1100 degrees C for 2 hours in argon atmosphere. USE - Preparation of nitrogen- and sulfur-doped graphene-graphene nanobelts aerogel used for preparing electrode material (claimed) of supercapacitor. ADVANTAGE - The electrode material formed using nitrogen- and sulfur-doped graphene-graphene nanobelts aerogel has excellent electrochemical performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use of nitrogen- and sulfur-doped graphene-graphene nanobelts aerogel for preparing electrode material. Nitrogen- and sulfur-doped graphene-graphene nanobelts aerogel, acetylene black and polytetrafluoroethylene are added to same weighing bottle in the mass ratio of 90:5:5, stirred, and obtained paste material is applied to nickel foam as current collector. The resultant material is dried under vacuum at 120 degrees C for 24 hours to obtain electrode.
