ELECTRODE FOR ELECTRICAL DOUBLE-LAYER CAPACITOR AND ELECTRICAL DOUBLE-LAYER CAPACITOR

摘要

PROBLEM TO BE SOLVED: To provide an electrode for an electrical double-layer capacitor, having an electrode layer excellent in surface flatness and adhesion, and has a high density.;SOLUTION: In the electrode for an electrical double-layer capacitor, an electrode composition layer containing an electrode active material, a conductive material, a binding agent, and a diffusing agent is formed on a current collector. The diffusing agent is a water soluble high polymer diffusing agent which contains a sulfonic group, a sulfonic base, a sulfate group, or a sulfate base and its content is 0.1 to 10 wt.% based on SO₃. The electrode for an electrical double-layer capacitor is used for an electrical double-layer capacitor.;COPYRIGHT: (C)2010,JPO&INPIT
