This tutorial review provides a brief summary of recent research progress on carbon-based electrode materials for supercapacitors, as well as the importance of electrolytes in the development of supercapacitor technology. The basic principles of supercapacitors, the characteristics and performances of various nanostructured carbon-based electrode materials are discussed. Aqueous and non-aqueous electrolyte solutions used in supercapacitors are compared. The trend on future development of high-power and high-energy supercapacitors is analyzed.read more

Features of a Double Electric Layer on Carbon in a Broad Temperature Range. Measurements in Water
TL;DR: In this paper, a double electric layer on carbon material has been studied for the first time in water in the temperature range from room temperature to 300° ˚ ǫ, and a decisive contribution of pseudocapacity was determined by the processes with surface groups, and the slowness of these processes has been stated from the dependence of current voltage curves on temperature and the voltage sweep rate.
