▎ 摘　　要

NOVELTY - Supercapacitor comprises a working electrode formed with a first activated material with nitrogen-doping porous graphene, a counter electrode formed with a second activated material with nitrogen-doping porous graphene, and a separator arranged between the working electrode and the counter electrode, where the working electrode, the counter electrode and the separator are soaked in an organic electrolyte. USE - As supercapacitor. ADVANTAGE - The method provides a simple and efficient production method of nitrogen-doping porous graphene: by fast increasing temperature and continuously injecting nitric oxide (NO) gas to make nitrogen-doping porous graphene by one step, and add it into activated carbon electrodes to make supercapacitor with high performance, such as high conductivity and capacitance. The method can reduce remaining functional groups and simplify the steps for making supercapacitor with efficiency and convenience. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a production method of supercapacitor, comprising: making an activated material with nitrogen-doping porous graphene; deposing the activated material on a conductive substrate to form a working electrode and a counter electrode; and adsorbing organic electrolyte on surfaces of the working electrode and the counter electrode.
