Title:
ELECTROCHEMICAL CELL AND ELECTROCHEMICAL CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2011/034163
Kind Code:
A1
Abstract:
Disclosed is an electrochemical cell, which comprises a positive electrode, a negative electrode that is arranged so as to face the positive electrode, and an electrolyte solution in which the positive electrode and the negative electrode are immersed. The positive electrode and/or the negative electrode is provided with a penetrating portion that penetrates the positive electrode and/or the negative electrode in the thickness direction. Also disclosed is an electrochemical capacitor, which comprises a positive electrode, a negative electrode, and an electrolyte solution in which the positive electrode and the negative electrode are immersed. When the support region of the negative electrode active material of the negative electrode is projected on the support region of the positive electrode active material of the positive electrode along the facing direction, the ratio of the support area of the positive electrode active material relative to the support area of the negative electrode active material in the projection plane is less than 1.
