ABSTRACT:
An electrode assembly is adapted to prevent the separator from contracting due to heat that is generated near the electrode tab during overcharging, over-discharging, or in the case of an internal short circuit. The electrode assembly also prevents an additional short circuit between the electrode plates. A rechargeable battery that comprises the electrode assembly is also provided. The present invention prevents the electrode tab from being short-circuited due to increased heat generation during overcharging or in the case of a short circuit, thus improving the safety of the rechargeable battery.
