Abstract

A battery is provided including a battery cell having main top and bottom surfaces, and a plurality of side surfaces; and at least one resin section including a cured resin that covers at least three of the plurality of side surfaces of the battery cell, but that does not cover substantially all of the top and bottom surfaces of the battery cell.

First claim

The application is claimed as follows:

1. A battery comprising:
a battery cell having main top and bottom surfaces, and a plurality of side surfaces; and
at least one resin section including a cured resin that covers at least three of the plurality of side surfaces of the battery cell, but that does not cover substantially all of the top and bottom surfaces of the battery cell,
wherein the battery cell includes a cell main body including a battery element, and an exterior material that covers the battery element, the resin sections being formed on the exterior material,
wherein the exterior material includes a fusion portion that is folded back to contact the cell main body,
wherein a height (D) of at least one of the resin sections and a height (B) of the folded back part of the fusion portion satisfy the following relationship D>B, and.
wherein at least part of one of the resin sections contacts and is formed between the folded back part of the fusion portion and the cell main body.

2. The battery according to claim 1 , wherein the resin section also covers at least one corner of adjacent side surfaces of the battery cell.

3. The battery according to claim 1 , wherein the resin sections have a flexible characteristic.

4. The battery according to claim 1 , wherein at least one of the resin sections has a bent shape that conforms to a shape of one of the side surfaces of the battery cell.

5. The battery according to claim 1 , wherein at least one of the resin sections covers a fourth side of the battery cell, and wherein a substrate section is formed between the resin section and the fourth side of the battery cell.

6. The battery according to claim 5 , wherein the resin section covering the fourth side of the battery cell has a box shape having an opening in one surface thereof, the resin section formed around an end of the battery cell.

7. The battery according to claim 1 , wherein the resin sections include a fibrous filler material.

8. The battery according to claim 1 , wherein a highest point of at least one of the resin sections does not exceed a highest point of a cell main body of the battery cell in a thickness direction thereof.

9. The battery according to claim 1 , wherein a thickness (A) of a cell main body of the battery cell and a height (D) of at least one of the resin sections satisfy the following relationship A≧D.

10. An electronic device including the battery of claim 1 .

11. An electric vehicle including the battery of claim 1 , and further comprising:
a conversion device to which electric power is supplied from the battery and which converts the electric power to a driving force of the electronic vehicle; and
a control device that performs information processing relating to a vehicle control on the basis of information relating to the battery.

12. An electrical storage device including the battery of claim 1 .

13. An electrical storage system including the battery of claim 1 , and further comprising an electric power information transmitting and receiving unit that transmits and receives electric power information to and from other apparatuses through a network,
wherein a charge and discharge control of the battery is performed on the basis of the information that is received by the transmitting and receiving unit.

14. A wearable terminal including the battery of claim 1 , and further comprising an electronic apparatus main body including an electronic circuit, the electronic circuit being electrically connected to the electronic circuit.

15. The wearable terminal according to claim 14 , wherein the battery is removable from the electronic apparatus main body.

16. The wearable terminal according to claim 14 , wherein the electronic apparatus main body has a curved shape.

17. The wearable terminal according to claim 14 , wherein the electronic apparatus main body has flexible and deformable characteristics.

18. A battery comprising:
a battery cell having main top and bottom surfaces, a plurality of side surfaces, and a plurality of corners; and
at least one resin section including a cured resin that covers portions of at least two corners of the battery cell, but that does not cover substantially all of the top and bottom surfaces of the battery cell,
wherein the battery cell includes a cell main body including a battery element, and an exterior material that covers the battery element the resin sections being formed on the exterior material,
wherein the exterior material includes a fusion portion that is folded back to contact the cell main body,
wherein a height (D) of at least one of the resin sections and a height (B) of the folded back part of the fusion portion satisfy the following relationship D>B, and
wherein at least part of one of the resin sections contacts and is formed between the folded back part of the fusion portion and the cell main body.

19. The battery according to claim 18 , comprising a plurality of separate resin sections, each resin section covering a different corner of the battery cell.

20. The battery according to claim 18 , wherein at least one of the resin sections covers a side of the battery cell, and wherein a substrate section is formed between the resin section and the side of the battery cell.

21. The battery according to claim 18 , wherein the resin sections include a fibrous filler material.

22. A battery comprising:
a battery cell having a plurality of side surfaces and at least one curved surface connecting the side surfaces; and
at least one resin section that covers the side surfaces of the battery cell, but that does not cover at least substantially all of the curved surface of the battery cell,
wherein the battery cell includes a cell main body including a battery element., and an exterior material that covers the battery element, the resin sections being formed on the exterior material,
wherein the exterior material includes a fusion portion that is folded back to contact the cell main body,
wherein a height (D) of at least one of the resin sections and a height (B) of the folded back art of the fusion portion satisfy the following relationship D>B and
wherein at least part of one of the resin sections contacts and is formed between the folded back part of the fusion portion and the cell main body.

23. The battery according to claim 22 , wherein the resin sections have a flexible characteristic.

24. The battery according to claim 22 , wherein the resin sections include a fibrous filler material.

25. The battery according to claim 22 , wherein the curved surface is a curved plate shape or an approximate curved plate shape.
