Electrochemical studies of modified carbon black in supercapacitors

Abstract

The development of energy storage systems, in particular, supercapacitors, is associated with the development of new materials and technologies for their processing. In the modern world, the production of supercapacitors, as a promising class of pulsed energy storage devices, is actively developing in communication, with the expansion of their applications ranging from portable electronics and the Internet of things to application in «MicroGrid» and alternative energy. Therefore, work on the manufacture and study of new carbon materials for SC electrodes is an important task. In this work, comparative electrochemical studies of carbon-carbon nanocomposites based on carbon black with a commercial sample of active carbon used in the manufacture of SC were carried out. It has been established that experimental samples of nanocomposites with increased current loads have higher performance characteristics: specific capacity and stability during cycling.The development of energy storage systems, in particular, supercapacitors, is associated with the development of new materials and technologies for their processing.
