Abstract

The invention discloses pitch-based spherical capacitor carbon and a preparation method thereof. According to the preparation method, one or a combination of Pluronic F127 and Pluronic P123 is selected as a template agent, the pitch-based spherical capacitor carbon is prepared by adopting a template method and a one-step carbonization and activation method, and the specific surface area and pore size distribution of the pitch-based spherical capacitor carbon are controlled by controlling the use amount of the template agent and activation conditions, so that the pitch-based spherical capacitor carbon is obtained. The problem that the pore structure of capacitor carbon prepared in a traditional process is difficult to regulate and control is solved; asphalt is used as a raw material and is wide in source, low in price and easy to obtain, and the preparation cost of the asphalt-based capacitor carbon is reduced; meanwhile, the preparation method is simple and environment-friendly, the problems that alkali sewage is difficult to treat and pollution is caused by follow-up washing of a traditional alkali activation method are solved, the green preparation requirement is met, and the method is suitable for large-scale production and has potential application value in the field of preparation of supercapacitor electrode materials and the like.
