ACTIVATED CARBON FOR ELECTROCHEMICAL ELEMENT AND ELECTROCHEMICAL ELEMENT USING THE SAME
First Claim
1. Activated carbon used for an electrochemical element comprising the activated carbon and an electrolytic solution,wherein under definitions that van der Waals molecular diameters of a cation, an anion, and a solvent contained in the electrolytic solution are denoted by Lc, La, and Ls, respectively;
- minimum widths of van der Waals molecules of the cation, the anion, and the solvent are denoted by Lmin,c, Lmin,a, and Lmin,s, respectively;
a maximum value of Lc, La, Ls, Lmin,c, Lmin,a, and Lmin,s is denoted by W1; and
a minimum values of (Lc+La), (Lc+Ls), (La+Ls), (Lmin,c+Lmin,a), (Lmin,c+Lmin,s), and (Lmin,a+Lmin,s) is denoted by W2,a total pore volume of the activated carbon in which a slit width obtained by an MP method is W1 or more and W2 or less is 15% or more of a total pore volume in which the slit width is 2.0 nm or less.

Abstract
Van der Waals molecular diameters of a cation, an anion, and a solvent contained in an electrolytic solution are denoted by Lc, La, and Ls, respectively. The minimum widths of van der Waals molecules of the cation, anion, and solvent are denoted by Lmin,c, Lmin,a, and Lmin,s, respectively. The maximum values of Lc, La, Ls, Lmin,c, Lmin,a, and Lmin,s is denoted by W1. The minimum values of (Lc+La), (Lc+Ls), (La+Ls), (Lmin,c+Lmin,a), (Lmin,c+Lmin,s), and (Lmin,a+Lmin,s) is denoted by W2. Under these definitions, the total pore volume of the activated carbon in which a slit width obtained by the MP method is W1 or more and W2 or less is 15% or more of the total pore volume in which the slit width is 2.0 nm or less.
