Abstract: Supercapacitors are energy storage devices which combine the advantages of secondary batteries and dialectical capacitors. Supercapacitors boast such characteristics as high power density, high charge/discharge efficiency, long cycle life and wide operation temperature. CO2 conversion into various carbon materials is recently developed and is considered as a promising technique towards green fabrication of carbon-based energy-storage materials. This review starts from different strategies for fabricating high-performance carbon-based electrodes, introduces the development of CO2 conversion methods, including direct combustion, high-temperature magnesiothermic reduction and self-propagating high-temperature synthesis, and then gives a detailed discussion of application of CO2-derived carbon in supercapacitors. At the end of this review, the prospect of CO2 conversion in production of carbon materials and fabrication of supercapacitors is given.

Key words: supercapacitor, CO2 conversion, carbon materials, energy storage
