Abstract

The present invention provides a battery, a method of forming a battery cell container, and an electronic device. The battery of the present invention comprises: a battery cell, and a battery cell container composed of two folded container portions formed by stretching in one thin sheet, wherein, in each container portion, among the planes where the walls of each container exist, at least two planes are inclined to the plane where the thin sheet section for forming the container portion exists. Through the implementation of the present invention, a larger volume of battery container can be obtained with the same or less material as well as easy positioning.

Claims (39)

1. A battery, comprising:

a battery cell, and

a battery cell container substantially cylindrical in shape, wherein the battery cell container includes a first folded container portion and a second folded container portion, each provided in a thin sheet,

wherein each folded container portion includes a first wall inclined toward a plane where the thin sheet exists, wherein the first wall does not intersect the plane where the thin sheet exists, wherein the plane where the thin sheet exists is superposed into each folded container portion, wherein the plane superposed in the first container portion is perpendicular to a section plane passing through a circle center of a second wall and a circle center of a third wall, and wherein the plane in the first container portion is not parallel nor perpendicular to the second wall or to the third wall.

2. The battery according to claim 1 , wherein a line formed at the intersection of the plane in the first container with the section plane is a diagonal of the section plane.

3. The battery according to claim 1 , wherein a folding line between the first folded container portion and the second folded container portion is parallel to a central axis direction of a cylinder formed by the first folded container portion and the second folded container portion.

4. The battery cell container according to claim 1 , wherein a folding line between the first folded container portion and the second folded container portion is perpendicular to a central axis direction of a cylinder formed by the first folded container portion and the second folded container portion.

5. The battery according to claim 1 , wherein a mating plane of the first folded container portion and the second folded container portion is neither parallel nor perpendicular to the second wall or to the third wall, and the mating plane is perpendicular to the section plane passing through the circle centers of the second and third walls.

6. An electronic device, comprising:

an electronic device main body and a battery supplying power to the electronic device main body, wherein,

the battery comprises:

a battery cell, and

a battery cell container including two folded container portions molded in a thin sheet,

wherein, in each container portion, among the planes where the walls of each container exist, a first plane is inclined to the plane where the thin sheet exists and the wall where the first plane exists does not intersect the plane where the thin sheet exists, and

wherein the battery cell container includes a second wall that intersects and is perpendicular to the plane where the thin sheet exists, and a third wall that intersects the plane where the thin sheet exists.

7. The electronic device according to claim 6 , wherein the battery cell container is in an unfolded state.

8. The electronic device according to claim 7 , wherein the battery cell container further includes a fourth wall and a fifth wall that are each perpendicular to the plane where the thin sheet exists at the third wall.

9. The electronic device according to claim 6 , wherein the battery cell container is in a folded state.

10. The electronic device according to claim 9 , wherein the battery cell container further includes a fourth wall and a fifth wall that each intersects the plane where the thin sheet exists at an internal angle greater than 90 degrees at the third wall.

11. A battery, comprising:

a battery cell, and

a battery cell container substantially cylindrical in shape, wherein the battery cell container includes a first folded container portion and a second folded container portion, each provided in a thin sheet,

wherein each folded container portion includes a first wall inclined toward a plane where the thin sheet exists, wherein the first wall does not intersect the plane where the thin sheet exists, and wherein a folding line between the first folded container portion and the second folded container portion is parallel to a central axis direction of a cylinder formed by the first folded container portion and the second folded container portion.

12. A battery, comprising:

a battery cell, and

a battery cell container substantially cylindrical in shape, wherein the battery cell container includes a first folded container portion and a second folded container portion, each provided in a thin sheet,

wherein each folded container portion includes a first wall inclined toward a plane where the thin sheet exists, wherein the first wall does not intersect the plane where the thin sheet exists, and wherein a folding line between the first folded container portion and the second folded container portion is perpendicular to a central axis direction of a cylinder formed by the first folded container portion and the second folded container portion.

13. A battery, comprising:

a battery cell, and

a battery cell container, wherein the battery cell container includes a first folded container portion and a second folded container portion, each provided in a thin sheet,

wherein each folded container portion includes a first wall inclined toward a plane where the thin sheet exists, wherein the first wall does not intersect the plane where the thin sheet exists, and wherein a mating plane of the first folded container portion and the second folded container portion is neither parallel nor perpendicular to a second wall or to a third wall, and the mating plane is perpendicular to a section plane passing through the circle centers of the second and third walls.

14. A battery, comprising:

a battery cell, and

a battery cell container, wherein the battery cell container includes a first folded container portion and a second folded container portion, each provided in a thin sheet,

wherein each folded container portion includes a first wall inclined toward a plane where the thin sheet exists, wherein the first wall does not intersect the plane where the thin sheet exists, and wherein the battery cell container further includes a second wall that intersects and is perpendicular to the plane where the thin sheet exists, and a third wall that intersects the plane where the thin sheet exists.

15. The battery according to claim 14 , wherein the battery cell container is in an unfolded state.

16. The battery according to claim 15 , wherein the battery cell container further includes a fourth wall and a fifth wall that are each perpendicular to the plane where the thin sheet exists at the third wall.

17. The battery according to claim 14 , wherein the battery cell container is in a folded state.

18. The battery according to claim 17 , wherein the battery cell container further includes a fourth wall and a fifth wall that each intersects the plane where the thin sheet exists at an internal angle greater than 90 degrees at the third wall.
