Non-aqueous electrolyte secondary battery

A nonaqueous electrolyte secondary battery comprising:

• a roll electrode group including a positive electrode plate, in which a positive electrode active material layer is disposed on each of a roll inner surface and a roll outer surface of a band positive electrode collector, and a negative electrode plate, in which a negative electrode active material layer is disposed on each of a roll inner surface and a roll outer surface of a band negative electrode collector, that are rolled with a separator interposed therebetween;
• and
• a tape attached to an outermost circumferential surface of the electrode group so as to fix a rolling-end edge of the electrode group to the outermost circumferential surface of the electrode group,
• wherein the tape has two adhesion regions including a base material layer and an adhesive layer and a non-adhesion region that is interposed between the two adhesion regions and that is composed of the base material layer only, and
• wherein the non-adhesion region straddles a rolling-end edge of each of the positive electrode active material layer on a roll inner side of the positive electrode collector and the positive electrode active material layer on a roll outer side of the positive electrode collector when the electrode group is viewed from a roll center axis of the roll electrode group toward an outside of the roll electrode group, and
• the negative electrode plate includes a plain region in which the negative electrode active material layer is not disposed on either surface of the negative electrode collector in an end portion of a rolling-end side thereof.
