Abstract
Immobilization tapes include first immobilization tapes disposed across an electrode assembly upper edge, second immobilization tapes disposed across the electrode assembly lower edge, and third immobilization tapes disposed across the electrode assembly side edges. The first immobilization tapes are disposed on the outer sides of two protrusion positions from a positive electrode tab and a negative electrode tab within the electrode assembly upper edge. One pair or more each of the first, second and third immobilization tapes are disposed over the electrode assembly. In the length direction of the electrode assembly upper edge, each of the first, second and third immobilization tape pairs is disposed symmetrically, centered around a central line extending in the top-down direction from the midpoint of the electrode assembly upper edge.
