Abstract
Embodiments relate to a secondary battery. The secondary battery includes a first electrode plate on which a notching pattern is disposed for each turn of winding, a second electrode plate which is wound together with the first electrode plate and on which a notching pattern is disposed for each turn, and a separator disposed between the first electrode plate and the second electrode plate and configured to electrically insulate the first electrode plate and the second electrode plate from each other. Each of the first electrode plate and the second electrode plate is folded and wound along a folding line for each turn.

A secondary battery comprising:
- a first electrode plate on which a notching pattern is disposed for each turn of a winding process;
- a second electrode plate that is wound with the first electrode plate and on which a notching pattern is disposed for each turn;
- and
- a separator disposed between the first electrode plate and the second electrode plate the separator being configured to electrically insulate the first electrode plate and the second electrode plate from each other,
- wherein each of the first electrode plate and the second electrode plate is folded and wound along a folding line for each turn.
A secondary battery comprising:
- a case;
- an electrode assembly accommodated in the case, the electrode assembly including:
- a first electrode plate on which a notching pattern is disposed for each turn of winding;
- a first electrode tab disposed at one side of an end of the first electrode plate in a longitudinal direction;
- a second electrode plate that is wound together with the first electrode plate and on which a notching pattern is disposed for each turn;
- a second electrode tab disposed at one side of an end of the second electrode plate in a longitudinal direction;
- a separator disposed between the first electrode plate and the second electrode plate, the separator being configured to electrically insulate the first electrode plate and the second electrode plate from each other;
- and
- wherein the first electrode plate, the second electrode plate, and the separator are wound,
- wherein each of the first electrode plate and the second electrode plate is folded and wound along a folding line for each turn.
