Abstract
A rechargeable battery includes an electrode assembly having a first electrode and a second electrode; a case housing the electrode assembly; a cap plate coupled to the case; a short-circuit tab electrically coupled to the second electrode and having an opening; a short-circuit member electrically coupled to the first electrode and configured to be moved by a change in pressure to be electrically coupled to the short-circuit tab; and a cover covering the opening in the short-circuit tab.
Claims7
A rechargeable battery comprising:
- an electrode assembly comprising a first electrode and a second electrode;
- a case housing the electrode assembly;
- a cap plate coupled to the case;
- a short-circuit tab electrically coupled to the second electrode, the short-circuit tab having an opening and a protrusion extending towards the electrode assembly;
- a short-circuit member electrically coupled to the first electrode and configured to be moved by a change in pressure to be electrically coupled to the short-circuit tab;
- a cover covering the opening in the short-circuit tab;
- and
- an upper insulating member located between the short-circuit tab and the cap plate, a first fixing portion configured to be coupled to the upper insulating member on a sidewall of the cover, and a second fixing portion configured to be coupled to the first fixing portion on the upper insulating member.
