Abstract
A secondary battery includes an electrode assembly including a first electrode with a first electrode tab, a separator, and a second electrode with a second electrode tab, a case accommodating the electrode assembly, the case being electrically connected to the second electrode tab, a cap assembly that seals an open one side of the case, the cap assembly being electrically connected to the first electrode tab, and an insulation sheet attached to the cap assembly, the insulation sheet electrically insulating the first electrode tab from the electrode assembly.
Claims20
A secondary battery, comprising:
- an electrode assembly including a first electrode with a first electrode tab, a separator, and a second electrode with a second electrode tab;
- a case accommodating the electrode assembly, the case being electrically connected to the second electrode tab;
- a cap assembly that seals an open one side of the case, the cap assembly being electrically connected to the first electrode tab;
- and
- an insulation sheet attached to the cap assembly, the insulation sheet electrically insulating the first electrode tab from the electrode assembly.
A method of manufacturing a secondary battery, the method comprising:
- accommodating an electrode assembly in a case, the electrode assembly including a first electrode with a first electrode tab formed therein, a separator, and a second electrode with a second electrode tab formed therein;
- disposing a cap assembly to be in contact with the first electrode tab;
- combining the first electrode tab to the cap assembly;
- attaching an insulation sheet to the cap assembly, such that the first electrode tab is not exposed;
- and
- combining the cap assembly to the case.
