Abstract:
An electrode assembly is an electrode assembly of a lithium ion secondary battery in which sheet-like positive electrodes and sheet-like negative electrodes are alternately stacked, with bag-like separators interposed therebetween. The area of the first main surface of each of the positive electrodes is smaller than the area of the first main surface of each of the negative electrodes, and the area of the second main surface of each of the positive electrodes is smaller than the area of the second main surface of each of the negative electrodes. The first main surfaces of the positive electrodes and the negative electrodes are opposed to each other, with the respective bag-like separators interposed therebetween, and the second main surfaces of the positive electrodes and the negative electrodes are opposed to each other, with the respective bag-like separators interposed therebetween.

Claim (Index 6):
A method for producing an electrode assembly of a lithium ion secondary battery, comprising:\n an positive electrode forming step of continuously applying positive electrode active material to front and back surfaces of a band-like positive electrode collector to form a band-like positive electrode member; a negative electrode forming step of continuously applying negative electrode active material to front and back surfaces of a band-like negative electrode collector to form a band-like negative electrode member; an positive electrode cutting step of continuously cutting positive electrodes, each having a first main surface and a second main surface having an area smaller than an area of the first main surface, out of the band-like positive electrode member; a negative electrode cutting step of continuously cutting negative electrodes, each having a first main surface and a second main surface having an area smaller than an area of the first main surface, out of the band-like negative electrode member; and a stacking step of alternately stacking the positive electrodes and the negative electrodes, with respective separators interposed therebetween such that the first main surfaces of the cut positive electrodes and the cut negative electrodes are opposed to each other, with the respective separators interposed therebetween, and the second main surfaces of the cut positive electrodes and the cut negative electrodes are opposed to each other, with the respective separators interposed therebetween.
