Abstract

The present disclosure relates to a rechargeable battery including: an electrode assembly including a first electrode, a second electrode, and a separation layer interposed between the first electrode and the second electrode, a first electrode tab electrically connected to the first electrode, a second electrode tab electrically connected to the second electrode, and a first exterior member and a second exterior member receiving the electrode assembly and disposed to face each other, wherein at least one of the first exterior member and the second exterior member includes at least one of a first draw-out unit drawing out the first electrode tab and a second draw-out unit drawing out the second electrode tab, and a display device including the same.

First claim

The invention claimed is:

1. A rechargeable battery comprising:
an electrode assembly comprising a first electrode, a second electrode, and a separation layer interposed between the first electrode and the second electrode;
a first electrode tab electrically connected to the first electrode;
a second electrode tab electrically connected to the second electrode; and
a first exterior member and a second exterior member receiving the electrode assembly and disposed to face each other,
wherein at least one selected from the first exterior member and the second exterior member comprises at least one selected from a first draw-out unit drawing out the first electrode tab and a second draw-out unit drawing out the second electrode tab, and
wherein the at least one selected from the first draw-out unit and the second draw-out unit is a perforation in the first exterior member or the second exterior member.

2. The rechargeable battery of claim 1 , wherein
the first draw-out unit and the second draw-out unit are disposed with a predetermined interval on at least one selected from the first exterior member and the second exterior member.

3. The rechargeable battery of claim 1 , wherein
the first draw-out unit is disposed at a first end of the first exterior member, and
the second draw-out unit is disposed at a second end facing the first end of the first exterior member.

4. The rechargeable battery of claim 3 , wherein
the first draw-out unit and the second draw-out unit are disposed to face each other in a length direction of the rechargeable battery.

5. The rechargeable battery of claim 1 , wherein
the first draw-out unit is disposed at a first end of the second exterior member, and
the second draw-out unit is disposed at a second end facing the first end of the second exterior member.

6. The rechargeable battery of claim 5 , wherein
the first draw-out unit and the second draw-out unit are disposed to face each other in a length direction of the rechargeable battery.

7. A rechargeable battery comprising:
an electrode assembly comprising a first electrode, a second electrode, and a separation layer interposed between the first electrode and the second electrode;
a first electrode tab electrically connected to the first electrode;
a second electrode tab electrically connected to the second electrode; and
a first exterior member and a second exterior member receiving the electrode assembly and disposed to face each other,
wherein at least one selected from the first exterior member and the second exterior member comprises at least one selected from a first draw-out unit drawing out the first electrode tab and a second draw-out unit drawing out the second electrode tab,
wherein the first draw-out unit is disposed at one end of the first exterior member, and
wherein the second draw-out unit is disposed at one end of the second exterior member.

8. A rechargeable battery comprising:
an electrode assembly comprising a first electrode, a second electrode, and a separation layer interposed between the first electrode and the second electrode;
a first electrode tab electrically connected to the first electrode;
a second electrode tab electrically connected to the second electrode; and
a first exterior member and a second exterior member receiving the electrode assembly and disposed to face each other,
wherein at least one selected from the first exterior member and the second exterior member comprises at least one selected from a first draw-out unit drawing out the first electrode tab and a second draw-out unit drawing out the second electrode tab,
wherein the first draw-out unit is disposed at one end of the second exterior member, and
wherein the second draw-out unit is disposed at one end of the first exterior member.

9. The rechargeable battery of claim 1 , wherein
the first electrode tab extends integrally with an uncoated region of the first electrode, and
the second electrode tab extends integrally with an uncoated region of the second electrode.

10. The rechargeable battery of claim 1 , further comprising
a first encapsulation unit and a second encapsulation unit respectively closing and sealing the first draw-out unit and the second draw-out unit.

11. The rechargeable battery of claim 10 , wherein
at least one selected from the first encapsulation unit and the second encapsulation unit comprises one kind or more selected from a group including polyisobutylene (PIB), butyl rubber, polytetrafluoroethylene (PTFE), epoxy, polydimethylsiloxane (PDMS), polypropylene (PP), polyethylene (PE), and ceramic.

12. The rechargeable battery of claim 10 , further comprising:
a third encapsulation unit covering the first draw-out unit; and
a fourth encapsulation unit covering the second draw-out unit.

13. The rechargeable battery of claim 12 , wherein
the third encapsulation unit and the fourth encapsulation unit are integrally extended.

14. The rechargeable battery of claim 12 , wherein
the third encapsulation unit and fourth encapsulation unit are at least one selected from an insulating tape, a sealing tape, a polyimide tape, and a polyimide silicon adhesive tape.

15. The rechargeable battery of claim 1 , wherein
at least one selected from the first exterior member and the second exterior member comprises a first resin layer, a moisture barrier layer, and a second resin layer.

16. The rechargeable battery of claim 1 , wherein
at least one selected from the first exterior member and the second exterior member is a single layer structure formed of one or more selected from a group including a polymer resin including polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polycarbonate, (PC), polyarylate (PAR), polyetherimide (PEI), polyethersulfone (PES), and polyimide (P 1 ), polypropylene (PP), polyethylene (PE), polytetrafluoroethylene (PTFE), chlorotrifluoroethylene (CTFE), nylon; and a thin ceramic including a thin glass and an aluminum oxide (Al 2 O 3 ).

17. The rechargeable battery of claim 16 , wherein
at least one thickness selected from the first exterior member and the second exterior member is 5 μm to 500 μm.

18. The rechargeable battery of claim 1 , wherein
