Secondary battery including a cap plate comprising an inversion plate |
摘要 |
A secondary battery includes an electrode assembly; a case accommodating the electrode assembly; a cap plate sealing the case and having an inversion plate; and an insulation plate having a short-circuit hole generally corresponding to the inversion plate and an air opening spaced from the short-circuit hole and fluidly connected to a top surface of the cap plate; a terminal plate coupled to a top surface of the insulation plate and electrically connected to the electrode assembly; and a terminal assembly including a sealing member coupled to a bottom surface of the insulation plate and formed to encompass the short-circuit hole and the air opening. |

1. A secondary battery, comprising:
an electrode assembly; a case accommodating the electrode assembly; a cap plate sealing the case and comprising an inversion plate; and an insulation plate on the cap plate and having a short-circuit hole generally corresponding to the inversion plate and an air opening spaced from the short-circuit hole and fluidly connected to a top surface of the cap plate; a terminal plate coupled to a top surface of the insulation plate and electrically connected to the electrode assembly; and a terminal assembly comprising a sealing member coupled to a bottom surface of the insulation plate and formed to encompass the short-circuit hole and the air opening, wherein the sealing member comprises a sealing ring extending around an edge of the short-circuit hole, a rib extending from one side of the sealing ring and surrounding at least a portion of a periphery of the air opening, and a protrusion part protruding away from the rib in a thickness direction. |
