Abstract
A cell structure for a secondary battery includes an electrode assembly including a plurality of electrodes, a plurality of electrode tabs extending from the electrodes to an outside of the electrode assembly, and a plurality of lead tabs electrically connected to the electrode tabs and contacting the electrode assembly. In the cell structure, a part of each of the lead tabs is folded, and the electrode tabs are inserted into the folded part of each of the lead tabs.
Claims14
A cell structure for a secondary battery, the cell structure comprising:
- an electrode assembly comprising a plurality of electrodes;
- a plurality of electrode tabs extending from the electrodes to an outside of the electrode assembly;
- a plurality of lead tabs electrically connected to the electrode tabs;
- and
- a fixing unit fixing the plurality of lead tabs,
- wherein
- a part of each of the lead tabs is folded,
- the folded part of each of the lead tabs is disposed to overlap the electrodes of the electrode assembly when viewed from a plan view in a thickness direction of the electrode assembly, and
- the fixing unit fixes the folded part of each of the lead tabs to at least one of two opposing surfaces of the electrode assembly, which are opposite to each other in the thickness direction thereof.
A secondary battery comprising:
- an exterior member;
- and
- a cell structure disposed in the exterior member,
- wherein the cell structure comprises:
- an electrode assembly comprising a plurality of electrodes;
- a plurality of electrode tabs extending from the electrodes to an outside of the electrode assembly;
