1. An electrode group for a flat secondary battery formed by winding a positive electrode and a negative electrode with a porous insulator interposed therebetween, and flattening the wound electrode group by pressing, wherein
bent portions are provided at ends of the electrode group in a direction of a long axis thereof, respectively, and
parts of the bent portions at the innermost of the electrode group are positioned opposite each other relative to a center line which passes a midpoint of the electrode group in a direction of a thickness thereof, and extends in the direction of the long axis.
2. The electrode group for the flat secondary battery of claim 1, wherein
the parts of the bent portions at the innermost of the electrode group are symmetric about a point on the center line.
3. A method for fabricating an electrode group for a flat secondary battery, the method comprising:
winding a positive electrode and a negative electrode with a porous insulator interposed therebetween to form an intermediate electrode group having a parallelogram-shaped lateral cross-section; and
pressing the intermediate electrode group to form a flat electrode group, wherein
bent portions are formed at ends of the electrode group in a direction of a long axis thereof, respectively, by pressing the intermediate electrode group, and
parts of the bent portions at the innermost of the electrode group are positioned opposite each other relative to a center line which passes a midpoint of the electrode group in a direction of a thickness thereof, and extends in the direction of the long axis.
4. The method of claim 3, wherein
the intermediate electrode group is pressed with a spacer having curved portions at longitudinal ends thereof inserted in a hollow part of the intermediate electrode group.
5. A flat secondary battery comprising:
the electrode group for the flat secondary battery of claim 1, and an electrolytic solution placed in a battery case.
The claims below are in addition to those above.
