A second portion of the packaging bag is recessed with respect to a first portion to form a first concave portion on an outer surface of the packaging bag. A second zone of the second electrode plate is recessed with respect to a first zone to form a second concave portion on the second electrode plate. In an extending direction of a first tab, a dimension by which the first zone extends beyond the first electrode plate is denoted as a1, a dimension by which the second zone extends beyond the first electrode plate is denoted as a2, and 0.2 mm≤a1−a2≤4 mm.",
