| Zusammenfassung: | The battery (100) disclosed here comprises one or more wound electrode bodies (20a,20b,20c) each composed of a strip-shaped first electrode plate (22) and a strip-shaped second electrode plate (24) superimposed and wound together with a strip-shaped separator (26) between the two, and a battery case (10) containing the wound electrode body or bodies (20a,20b,20c). The first electrode plate has multiple electrode tabs (22t) protruding from an edge (22e) extending in the longitudinal direction (W), and the multiple electrode tabs (22t) include a first electrode tab (27) having a straight part (27s) that is roughly perpendicular to the edge (22e) and has a length of at least 2 mm in the direction (Y) orthogonal to the edge (22e), and second electrode tabs (28a-28e) lacking the straight part (27s). |
