The acceleration of urbanization has made environmental problems increasingly prominent. With the continuous increase in the volume of urban sewage discharged annually, the problem of urban sludge pollution has gradually become an environmental problem in our country. At the same time, the expansion of grid-connected new energy has also continuously raised new challenges to low-cost and high-efficiency energy storage technology. This paper uses municipal sludge to prepare low-cost supercapacitors, that is, using municipal sludge as a raw material, through a series of physical and chemical processes such as drying, doping, impregnation, and activation, to prepare carbon-based porous electrode materials that can be used for supercapacitors. On the one hand, it solves the problem of sludge disposal. On the other hand, it greatly reduces the cost of supercapacitors and provides a new idea for preparing supercapacitors.
