Abstract: A power storage cell includes: a wound electrode assembly which includes a positive plate (a first electrode) and a negative plate (a second electrode); and a case accommodating the wound electrode assembly. The positive plate includes: a positive current collector (a current collector); a positive electrode mixture layer (an electrode material) with which a portion of the positive current collector is coated; and a positive electrode tab lead (a tab lead). The positive current collector has an uncoated portion that is not coated with the positive electrode mixture layer. An overlapping portion is formed by folding the uncoated portion of the positive current collector in the radial direction of the wound electrode assembly. The positive electrode tab lead is disposed in the overlapping portion.

Abstract: The power storage cell includes a wound electrode body, a case, an internal gasket (a seal member), a positive electrode terminal (an external terminal), and a positive electrode connecting portion (a connecting member). The case includes a peripheral wall portion, a lower lid (first lid portion), and an upper lid (second lid portion). The lower lid has an exhaust valve for exhausting the gas in the case. A through hole (second through hole) is formed in the upper lid (second lid). The positive electrode connecting portion includes a columnar portion extending in the Z direction so as to penetrate the through hole of the upper lid and the through hole (first through hole) of the inner gasket. The inner gasket is disposed so as to cover the through hole from the inside of the case.
