ELECTRODE AND PROCESS FOR PRODUCING SAME, AND FLOW-THROUGH CAPACITOR USING SAME

摘要

Provided is an electrode which is suitable for use as an electrode for a flow-through capacitor and which exhibits a small electrode resistance and excellent durability. An electrode obtained by forming a porous electrode layer and an ion exchange layer on a current collector layer, characterized in that: the porous electrode layer contains a carbon material; the ion exchange layer contains an ion exchanger (A) which contains (1) a copolymer (A1+A2) composed of a vinyl alcohol monomer (A-1) and an ion exchange monomer (A-2) or (2) a mixture (B1+B2) of a vinyl alcohol-based polymer (B-1) and a polymer (B-2) having an ion exchange group; the ion exchanger (A) is crosslinked with a crosslinking agent which can form an acetal crosslinkage; and the degree of crosslinking of the ion exchanger (A) is 4.30 or less.
