Abstract

A belt with built-in batteries includes: a plurality of rechargeable batteries, each having a positive terminal and a negative terminal that protrude in two opposite directions; a positive reinforcing tab that electrically connects the positive terminals of the rechargeable batteries to each other; a negative reinforcing tab that electrically connects the negative terminals of the rechargeable batteries to each other; and a sheath that seals the positive and negative terminals of the rechargeable batteries and the positive and negative reinforcing tabs.

First claim

What is claimed is:

1. A belt with built-in batteries comprising:
a plurality of rechargeable batteries, each having a positive terminal and a negative terminal that protrude in two opposite directions;
a positive reinforcing tab that electrically connects the positive terminals of the rechargeable batteries to each other;
a negative reinforcing tab that electrically connects the negative terminals of the rechargeable batteries to each other; and
a sheath that seals the positive and negative terminals of the rechargeable batteries and the positive and negative reinforcing tabs.

2. The belt of claim 1 , wherein the positive reinforcing tab is welded to a side of each of the positive terminals facing a first direction, and the negative reinforcing tab is welded to a side of each of the negative terminals facing a second direction opposite to the first direction.

3. The belt of claim 1 , wherein the positive reinforcing tab and the negative reinforcing tab extend along a length of the sheath, and
the positive reinforcing tab is welded to a plurality of positive terminals and located on a first side of each of the rechargeable batteries, and the negative reinforcing tab is welded to a plurality of negative terminals and located on a second side of each of the rechargeable batteries opposite to the first side.

4. The belt of claim 1 , wherein the positive reinforcing tab comprises a plurality of positive reinforcing tabs and is welded to either side of each positive terminal.

5. The belt of claim 1 , wherein the negative reinforcing tab comprises a plurality of negative reinforcing tabs and is welded to either side of each negative terminal.

6. The belt of claim 1 , wherein the positive reinforcing tab and the negative reinforcing tab extend along a length of the sheath, and
the positive reinforcing tab is welded to either side of each positive terminal, and the negative reinforcing tab is welded to either side of each negative terminal.

7. The belt of claim 1 , wherein the rechargeable batteries each comprise an electrode assembly formed by winding positive electrode, a negative electrode, and a separator.

8. The belt of claim 7 , wherein the positive terminal and the negative terminal protrude in the same direction as a winding axis of the electrode assembly.

9. The belt of claim 7 , wherein the positive terminal and the negative terminal protrude in a direction orthogonal to a winding axis of the electrode assembly.

10. The belt of claim 7 , wherein the rechargeable batteries comprise polymer batteries with a gel electrolyte.

11. The belt of claim 1 , wherein the rechargeable batteries are electrically connected in parallel by the positive reinforcing tab and the negative reinforcing tab.

12. The belt of claim 11 , wherein the rechargeable batteries are arranged in at least one line along a length of the sheath.

13. The belt of claim 12 , wherein the positive and negative terminals of one of the rechargeable batteries are placed to face the positive and negative terminals of another rechargeable battery adjacent in a length direction of the sheath.

14. The belt of claim 1 , wherein the positive terminals and the negative terminals are joined by a hinge structure, and the positive reinforcing tab and the negative reinforcing tab are installed in such a way as to cover the hinge structure.

15. The belt of claim 1 , the sheath integrally seals the positive terminals, the negative terminals, the positive reinforcing tab, and the negative reinforcing tab.

16. The belt of claim 15 , wherein the sheath comprises a laminate film.

17. The belt of claim 1 , wherein the positive reinforcing tab and the negative reinforcing tab are bent.

18. The belt of claim 1 , wherein the sheath further comprises a connecting portion that is configured to be connected to an electronic device located on one end of a length of the sheath and allows conduction between the rechargeable batteries and the electronic device.

19. The belt of claim 18 , further comprising buckle portions that are located at one end of the length of the sheath and the other end, respectively, to adjust the length of the sheath.

20. The belt of claim 1 , wherein the positive reinforcing tab and the negative reinforcing tab comprises a copper-containing metal.
