摘要:
The present invention provides a raw material carbon composition that is converted to a carbon material for an electrode in an electric double layer capacitor that can develop a high level of electrostatic capacity with good reproducibility without producing any synthetic pitch. The raw material carbon composition is converted to a carbon material for an electrode in an electric double layer capacitor upon activation treatment and is characterized in that, when the raw material carbon composition is carbonized in an inert gas atmosphere at a temperature of 1000 to 1500° C., the true relative density (RD) and the total hydrogen content (TH %) in the carbonized material obtained after the burning satisfy the following formula (1): RD=−0.75TH %+intercept (1) wherein the intercept is 2.160 or greater.
