Abstract
The present disclosure relates to a method for making a carbon aerogel electrode material. The method involves initially making a wet organic sol-gel form. The sol-gel form is carbonized at a temperature of from about 900° C. to about 1000° C., for from about 2 hours to about 4 hours. The carbonized sol-gel is then activated under carbon dioxide flow, for from about 0.5 hour to about 1.5 hours, at from about 900° C. to about 1000° C.
