Abstract

Official abstract text for this publication.

An exemplary embodiment provides a rechargeable battery including a case including an internal space and an opening and a cap plate coupled to the case to cover the opening. The cap plate may include a first portion having a first thickness, and a second portion continuously disposed along an edge of the cap plate and having a second thickness that is thicker than the first thickness.

First claim

Opening claim text (preview).

What is claimed is: 1. A rechargeable battery comprising: a case including an internal space and an opening; and a cap plate coupled to the case to cover the opening, wherein the cap plate comprises: a first portion having a first thickness; and a second portion having a second thickness that is thicker than the first thickness, wherein the second portion includes: a first barrier protruding from a first surface of the cap plate toward an outside of the case and being continuously disposed along an edge of the cap plate, and a second barrier protruding from a second surface of the cap plate toward the internal space of the case and being continuously disposed along the edge of the cap plate, the second surface of the cap plate being opposite to the first surface of the cap plate, and wherein the first and second barriers of the second portion of the cap plate are symmetric to one another with respect to the first portion of the cap plate. 2. The rechargeable battery as claimed in claim 1 , wherein a circumferential surface of the second barrier coincides with a circumferential surface of the cap plate. 3. The rechargeable battery as claimed in claim 2 , wherein the cap plate includes a terminal hole, a vent hole, and a third portion disposed along a circumference of the terminal hole and a circumference of the vent hole, the third portion having a third thickness that is thicker than the first thickness. 4. The rechargeable battery as claimed in claim 3 , wherein the third portion includes a third barrier protruding toward the internal space of the case from the second surface of the cap plate. 5. The rechargeable battery as claimed in claim 1 , wherein a circumferential surface of the second barrier does not coincide with a circumferential surface of the cap plate. 6. The rechargeable battery as claimed in claim 5 , wherein the cap plate includes a terminal hole, a vent hole, and a third portion disposed along a circumference of the terminal hole and a circumference of the vent hole, the third portion having a third thickness that is thicker than the first thickness. 7. The rechargeable battery as claimed in claim 6 , wherein the third portion includes a third barrier protruding toward the internal space of the case from the second surface of the cap plate. 8. The rechargeable battery as claimed in claim 1 , wherein the cap plate includes a terminal hole, a vent hole, and a third portion disposed along a circumference of the terminal hole and a circumference of the vent hole, the third portion having a third thickness that is thicker than the first thickness. 9. The rechargeable battery as claimed in claim 8 , wherein the third portion includes a third barrier protruding toward the internal space of the case from the second surface of the cap plate. 10. A rechargeable battery comprising: a case including an internal space and an opening; and a cap plate coupled to the case to cover the opening, the cap plate having a terminal hole and a vent hole, wherein the cap plate comprises: a first portion having a first thickness; a second portion continuously disposed along an edge of the cap plate and having a second thickness that is thicker than the first thickness; and a third portion having a third thickness that is thicker than the first thickness, wherein the third portion includes: a first barrier protruding from a first surface of the cap plate toward the internal space of the case from a surface of the cap plate and being continuously disposed along an edge of the terminal hole and an edge of the vent hole, and a second barrier protruding from a second surface of the cap plate toward an outside of the case and being continuously disposed along the edge of the terminal hole and the edge of the vent hole, the second surface of the cap plate being opposite to the first surface of the cap plate, and wherein the first and second barriers of the third portion of the cap plate are symmetric to one another with respect to the first portion of the cap plate.
