Abstract

A battery includes a conductive substrate, the conductive substrate including a first resin layer, a barrier layer, a second resin layer, a first electrode current collector layer, and a first electrode coating layer that are sequentially stacked inward from an outermost side of the battery, an exterior member disposed to face the conductive substrate, a sealing portion formed at edges of the conductive substrate and the exterior member, and at least one second inner electrode positioned between the conductive substrate and the exterior member and stacked using a separator as a border.

First claim

What is claimed is:

1. A battery, comprising:
a conductive substrate, the conductive substrate including a first resin layer, a barrier layer, a second resin layer, a first electrode current collector layer, and a first electrode coating layer that are sequentially stacked inward from an outermost side of the battery;
an exterior member disposed to face the conductive substrate;
a sealing portion formed at edges of the conductive substrate and the exterior member; and
at least one second inner electrode positioned between the conductive substrate and the exterior member and stacked using a separator as a border, wherein:
the barrier layer is made of a conductive metal, and
the second resin layer includes a plurality of conducting portions.

2. The battery as claimed in claim 1 , further comprising at least one first inner electrode,
wherein the at least one second inner electrode and the at least one first inner electrode are alternately stacked using the separator as a border.

3. The battery as claimed in claim 1 , wherein the sealing portion is formed on edges of the first electrode current collector layer and the exterior member.

4. The battery as claimed in claim 1 , wherein the sealing portion is formed on edges of the second resin layer and the exterior member.

5. The battery as claimed in claim 1 , wherein the sealing portion is formed on edges of the barrier layer and the exterior member.

6. The battery as claimed in claim 1 , wherein the sealing portion is formed on edges of the first resin layer and the exterior member.

7. The battery as claimed in claim 1 , wherein at least one of the first resin layer and the second resin layer includes one or more of polyimide (PI), polyetheretherketone (PEEK), polyethersulfone (PES), polyetherimide (PEI), polycarbonate (PC), or polyethylene terephthalate (PET).

8. The battery as claimed in claim 7 , wherein the first resin layer and the second resin layer are made of the same material.

9. The battery as claimed in claim 1 , wherein the sealing portion is formed of a material having the same heat expansion rate as that of at least one of the first resin layer and the second resin layer.

10. The battery as claimed in claim 1 , wherein the exterior member is a second conductive substrate.

11. The battery as claimed in claim 1 , further comprising a circuit film layer stacked on an external surface of the conductive substrate.

12. A battery pack comprising the battery as claimed in claim 1 as a flexible rechargeable unit battery.

13. A device comprising the battery pack as claimed in claim 12 as a power supply.

14. An electronic device comprising a battery as claimed in claim 1 .
