Patent ID: 10418187

Abstract:
The carbon porous body of the present disclosure includes micropores and mesopores. A micropore volume determined at a temperature of 77K by as plot analysis of a nitrogen adsorption isotherm is 100 (cm3 (STP)/g) or more. A BET specific surface area determined from the nitrogen adsorption isotherm is 1,000 m2/g or more. The derivative of the nitrogen adsorption isotherm is 300 (cm3 (STP)/g) or more over the range where relative pressure P/P0 in the nitrogen adsorption isotherm is from 0.10 to 0.20 inclusive, and the derivative of the nitrogen adsorption isotherm is 200 (cm3 (STP)/g) or more over the range where the relative pressure P/P0 in the nitrogen adsorption isotherm is from 0.20 to 0.95 inclusive. The amount of nitrogen adsorbed when the relative pressure P/P0 in the nitrogen adsorption isotherm is 0.98 is 1,200 (cm3 (STP)/g) or more.
