Abstract
A secondary battery includes an electrode stack having a separator, the separator including a first separator region, a second separator region, a third separator region, and a fourth separator region, a first negative electrode plate between the first separator region and the second separator region, and a first positive electrode plate between the third separator region and the fourth separator region, an insulating tape on a periphery of the electrode stack, and a case receiving the electrode stack and the insulating tape, wherein one side of the second separator region contacts one side of the third separator region.
Claims19
A secondary battery, comprising:
- an electrode stack comprising a separator, the separator including a first separator region, a second separator region, a third separator region, and a fourth separator region, a first negative electrode plate between the first separator region and the second separator region, and a first positive electrode plate between the third separator region and the fourth separator region;
- an insulating tape on a periphery of the electrode stack;
- and
- a case receiving the electrode stack and the insulating tape,
- wherein one side of the second separator region contacts one side of the third separator region.
A secondary battery, comprising:
- an electrode stack comprising a separator, the separator comprising a first separator region, a second separator region, a third separator region, a fourth separator region, and a fifth separator region, a first negative electrode plate between the first separator region and the second separator region, and a first positive electrode plate between the fourth separator region and the fifth separator region;
