摘要： The present disclosure provides an electrolytic capacitor for middle or high voltage application of 160 V or more, which can suppress the total amount of gas generated inside the electrolytic capacitor. An electrolytic capacitor includes anode foil on which dielectric oxide film is formed, and a cathode body. The cathode body includes cathode foil formed of valve action metal and a carbon layer formed on the cathode foil. The anode foil and the cathode body have capacitance so that when capacitance X of the anode foil per unit area is 1, ratio of capacitance Y of the cathode body per the same unit area is equal to or more than 10.

摘要： The present invention provides a conductive carbon which enables the achievement of an electricity storage device that has high energy density, while exhibiting improved charge/discharge cycle stability even during high voltage application. A conductive carbon according to the present invention is produced by a method which comprises: an oxidation step wherein a carbon starting material is subjected to an oxidation treatment, thereby obtaining an oxidation-treated carbon that spreads in a paste-like state when a pressure is applied thereto; and a heat treatment step wherein the oxidation-treated carbon is subjected to a heat treatment under a vacuum or in a non-oxidizing atmosphere. Since CO 2 is separated from the oxidation-treated carbon during the heat treatment process, the amount of CO 2 generated from the thus-obtained conductive carbon in the temperature range of from 25 °C to 200 °C is smaller than the amount of CO 2 generated from the oxidation-treated carbon in the temperature range of from 25 °C to 200 °C. It is preferable that the heat treatment is carried out in such a manner that the amount of CO 2 generated from the thus-obtained conductive carbon in the temperature range of from 25 °C to 200 °C is within the range of from 0.015 % by mass to 0.050 % by mass of the entire conductive carbon.
