ACTIVATED CARBON FOR ELECTROCHEMICAL ELEMENT AND ELECTROCHEMICAL ELEMENT USING THE SAME

摘要

Activated carbon used for an electrochemical element in which when W1 and W2 satisfy 1.0 nm ‰¤ W1 < W2 ‰¤ 2.0 nm, 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 of the activated carbon in which the slit width obtained by the MP method is 2.0 nm or less. Furthermore, an electrode layer of the electrochemical element includes activated carbon having a large pore volume in which the slit width is W1 or more and W2 or less.
