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 (30) includes a collector plate (32), an active material layer (33) formed on the collector plate (32), and a resin separator layer (34) formed on the active material layer (33), wherein a stripped laser-cut end (30sp), which is laser-cut in the thickness direction of the separator-integrated electrode plate and along the laser-cut edge (30es) forming a part of a peripheral edge (30e) of the separator-integrated electrode plate (30), has a resin penetrating infiltration part (33j) in which a resin forming a resin separator layer (34) penetrates over a width (Wa) larger than twice the thickness (Ts) of the resin separator layer (34).
