SEPARATOR-INTEGRATED ELECTRODE PLATE, ELECTRODE PLATE PAIR, STACKED ELECTRIC POWER STORAGE ELEMENT, AND METHOD OF MANUFACTURING SEPARATOR-INTEGRATED ELECTRODE PLATE

摘要

A separator-integrated electrode plate includes a current collector plate; an active material layer formed on the current collector plate; and a resin separator layer formed on the active material layer. A belt-like laser-cut end portion along a laser-cut edge that is laser-cut in a thickness direction of the separator-integrated electrode plate and forms part of a peripheral edge of the separator-integrated electrode plate has a resin-permeated portion in which a resin forming the resin separator layer permeates the active material layer over a width that is more than twice a thickness of the resin separator layer.
