Abstract
Provided is a secondary battery, which can prevent a protective circuit board and an electrode terminal from colliding with each other by providing a gasket including a support unit protruding from a top surface of a cap plate to be higher than the electrode terminal. The secondary battery includes an electrode assembly, a case accommodating the electrode assembly, a cap plate coupled to an opening of the case, an electrode terminal electrically connected to the electrode assembly and upwardly protruding through a terminal throughhole of the cap plate, and a gasket interposed between the cap plate and the electrode terminal and electrically insulating the cap plate and the electrode terminal from each other. The gasket includes a support unit protruding from the cap plate to be higher than the electrode terminal.

A secondary battery comprising:
- an electrode assembly;
- a case accommodating the electrode assembly;
- a cap plate coupled to an opening of the case;
- an electrode terminal electrically connected to the electrode assembly and upwardly protruding through a terminal throughhole of the cap plate;
- and
- a gasket interposed between the cap plate and the electrode terminal and electrically insulating the cap plate and the electrode terminal from each other,
- wherein the gasket includes a support unit protruding from the cap plate to be higher than the electrode terminal and a mounting unit that extends along a top surface of the cap plate wherein the electrode terminal extends higher from the cap plate than the mounting unit and the support unit extends upward higher from the cap plate than the electrode terminal.
A secondary battery comprising:
- an electrode assembly;
- a case having an opening that receives the electrode assembly;
- a cap plate having a terminal through hole coupled to the opening of the case;
- an electrode terminal electrically connected to the electrode assembly and upwardly protruding through the terminal through hole of the cap plate;
- a gasket interposed between the cap plate and the electrode terminal wherein the gasket electrically insulates the cap plate and the electrode terminal from each other and wherein the gasket includes a support unit protruding from an upper surface of the cap plate and a mounting unit that extends along a top surface of the cap plate wherein the electrode terminal extends higher from the cap plate than the mounting unit and the support unit extends upward higher from the cap plate than the electrode terminal;
- a protective circuit board position over the upper surface of the cap plate wherein the protective circuit board is mounted on the support unit and wherein the support unit is sized to space the protective circuit board from the electrode terminal.
