The positive electrode exposed portion protrudes outward in an axial direction of the wound electrode assembly relative to the separator and the negative electrode at one end in the axial direction of the wound electrode assembly. The negative electrode exposed portion protrudes outward in the axial direction of the wound electrode assembly relative to the separator and the positive electrode at the other end in the axial direction. The positive electrode exposed portion has a cutout portion at least in an outermost circumferential portion of the positive electrode.

摘要： An inspection method of a secondary battery includes a charging step, an aging step, a pre-inspection discharge step, a voltage adjustment step, a self-discharge inspection step, and a deficiency determination step. A discharge condition in the pre-inspection discharge step is determined so that a voltage difference accumulation value Vs satisfies a predetermined range. The voltage difference accumulation value Vs is calculated by accumulating a value obtained by subtracting an output voltage from a predetermined voltage over a duration from start of the pre-inspection discharge step to end thereof.
