Rechargeable battery |
摘要 |
A rechargeable battery including: an electrode assembly including a first electrode and a second electrode; a case containing the electrode assembly; a cap plate coupled to the case; a short-circuit tab electrically connected to the first electrode; and a short-circuit member electrically connected to the second electrode and configured to contact the short-circuit tab according to an increase of an internal pressure of the rechargeable battery, and the short-circuit member includes a connection portion having a plate shape, a support portion at an outer side of the connection portion, and a variable groove having a shape that is configured to change according to the increase of the internal pressure. |

1. A rechargeable battery comprising:
an electrode assembly comprising a first electrode and a second electrode; a case containing the electrode assembly; a cap plate coupled to the case; a short-circuit tab electrically connected to the first electrode; and a short-circuit member electrically connected to the second electrode and configured to contact the short-circuit tab according to an increase of an internal pressure of the rechargeable battery, wherein the short-circuit member comprises a connection portion having a plate shape, a support portion at an outer side of the connection portion, and a variable groove having a shape that is configured to change according to the increase of the internal pressure, and wherein the connection portion is configured to rise from a pre-deformation state in which the connection portion has an arc-shaped cross-section protruding toward the short-circuit tab to a deformed state and contact the short-circuit tab when the internal pressure of the rechargeable battery exceeds a reference pressure. |
