Double layer capacitor with high capacitance carbonaceous material electrodes

A double layer capacitor with electrodes produced from a carbonaceous material having a large capacitance obtained by heat-treating an activated carbon precursor at a temperature below 700 DEG C., preferably from 400 DEG to 500 DEG C., in an alkali metal hydroxide bath. In particular, its capacitanc...

Abstract A double layer capacitor with electrodes produced from a carbonaceous material having a large capacitance obtained by heat-treating an activated carbon precursor at a temperature below 700 DEG C., preferably from 400 DEG to 500 DEG C., in an alkali metal hydroxide bath. In particular, its capacitance per unit volume is several times larger, in some cases 7 or more times larger, as compared with conventional activated carbons for capacitors.
