Abstract
Official abstract text for this publication.
A rechargeable secondary battery includes: a case; an electrode assembly in the case; and a cap plate coupled to the case and protecting the electrode assembly, wherein the cap plate comprises a fuse part electrically connected to the electrode assembly.
First claim
Opening claim text (preview).
What is claimed is: 1. A secondary battery comprising: a case; an electrode assembly in the case; a cap plate coupled to the case and protecting the electrode assembly; and an insulation plate between the cap plate and the electrode assembly, wherein the cap plate comprises a fuse part electrically connected to the electrode assembly, the fuse part being directly formed on the cap plate and being configured to melt in response to a short-circuit current of the electrode assembly, wherein the fuse part passes through an opening in the insulation plate to be connected to the electrode assembly. 2. The secondary battery of claim 1 , wherein the fuse part protrudes from the cap plate toward the electrode assembly. 3. The secondary battery of claim 1 , further comprising a conductive plate-between the insulation plate and the electrode assembly, wherein the fuse part passes through the conductive plate to be connected to the electrode assembly. 4. The secondary battery of claim 3 , wherein the electrode assembly comprises a conductive tab extending toward the conductive plate, wherein the conductive tab is connected to the conductive plate. 5. The secondary battery of claim 1 , wherein the fuse part extends from the cap plate and is solid without a cavity inside. 6. The secondary battery of claim 1 , wherein the fuse part extends from the cap plate and is hollow with a cavity inside. 7. The secondary battery of claim 1 , wherein the fuse part is formed in a widthwise direction of the cap plate. 8. The secondary battery of claim 1 , wherein the fuse part is formed in a lengthwise direction of the cap plate. 9. The secondary battery of claim 1 , wherein the cap plate comprises a terminal plate on an opposite surface of a surface having the fuse part formed thereon. 10. The secondary battery of claim 9 , wherein the cap plate comprises a terminal fixing part constraining the terminal plate.
