| description | The invention provides a preparation method of high-capacity supercapacitor graphene conductive agent dispersion liquid. According to the preparation method, graphene powder is dispersed in a solventthrough hydroxyl anthraquinonyl quaternary ammonium salt, after a conductive agent is added, dispersion is conducted through a nano grinding machine, and thus the graphene conductive agent dispersionliquid is obtained. According to the dispersion liquid, a preparation technology is simple, raw materials are easy to obtain, and the production cost is low. Hydroxyl anthraquinonyl quaternary ammonium salt surface-modified graphene and the composed conductive agent have good wettability and electrochemical stability; and when the high-capacity supercapacitor graphene conductive agent dispersion liquid is used for a supercapacitor electrode material, a constituted supercapacitor has low internal resistance, the high electrostatic capacity, and the good circulation characteristic.
