  • Method for fabricating lithium ion secondary battery
    Publication number: 20030167627
    Abstract: By using a winding type electrode plate assembly resistant to displacement by wind-up and buckling and thus integrated at the time of the completion thereof, a lithium ion secondary battery, capable of suppressing deterioration in cycle characteristic and storage characteristic caused by expansion and shrinkage of the electrode plate due to charge/discharge cycles or by generation of gas during storage at high temperatures or the like, is accomplished.
