Abstract

The embodiment of the present application relates to the field of battery, and in particular relates to a battery, an electric apparatus, and a method for producing a battery. The battery of the present application includes: a battery cell; a box body configured for accommodating the battery cell and comprising a sleeve, and a first end cover and a second end cover for sealing both ends of the sleeve in a height direction respectively; a first insulating member, at least part of the first insulating member being located between the first end cover and the battery cell; and a second insulating member, at least part of the second insulating member being located between the second end cover and the battery cell; where an inner wall of the sleeve is provided with a fixing portion configured to fix the first insulating member and the second insulating member.

First claim

What is claimed is:

1. A battery, comprising:
a battery cell;
a box body, configured to accommodate the battery cell and comprising a sleeve and a first end cover and a second end cover for sealing both ends of the sleeve in a height direction respectively;
a first insulating member, at least part of the first insulating member being located between the first end cover and the battery cell; and
a second insulating member, at least part of the second insulating member being located between the second end cover and the battery cell;
wherein an inner wall of the sleeve is provided with a fixing portion, and the fixing portion is configured to fix the first insulating member and the second insulating member;
wherein the fixing portion is clamped to the first insulating member and the second insulating member; and
wherein the first insulating member and the second insulating member are provided with a hook, and the hook is configured to clamp the groove of the fixing portion.

2. The battery according to claim 1 , wherein the fixing portion comprises a convex ridge.

3. The battery according to claim 2 , wherein a side surface of the convex ridge is provided with an opening.

4. The battery according to claim 3 , wherein the opening is located at a side of the convex ridge close to the battery cell.

5. The battery according to claim 1 , wherein the fixing portion comprises a groove.

6. The battery according to claim 1 , wherein a distance exists between the fixing portion and at least one of both ends of the sleeve in the height direction, so that the first insulating member and/or the second insulating member are accommodated in the sleeve.

7. The battery according to claim 1 , wherein the fixing portion comprises a first fixing portion and a second fixing portion separately arranged in the height direction of the sleeve, and the first fixing portion is configured to fix the first insulating member, and the second fixing portion is configured to fix the second insulating member.

8. The battery according to claim 7 , wherein the first fixing portion and the second fixing portion are staggered to be disposed in a length direction or width direction of the sleeve.

9. The battery according to claim 1 , wherein the fixing portion is further configured to fix the first end cover and the second end cover.

10. An electric apparatus, comprising:
a battery, comprising:
a battery cell;
a box body, configured to accommodate the battery cell and comprising a sleeve and a first end cover and a second end cover for sealing both ends of the sleeve in a height direction respectively;
a first insulating member, at least part of the first insulating member being located between the first end cover and the battery cell; and
a second insulating member, at least part of the second insulating member being located between the second end cover and the battery cell;
wherein an inner wall of the sleeve is provided with a fixing portion, and the fixing portion is configured to fix the first insulating member and the second insulating member;
wherein the fixing portion is clamped to the first insulating member and the second insulating member;
wherein the first insulating member and the second insulating member are provided with a hook, and the hook is configured to clamp the groove of the fixing portion; and
wherein the battery is configured to provide electrical energy.

11. The electric apparatus according to claim 10 , wherein the fixing portion comprises a convex ridge.

12. The electric apparatus according to claim 11 , wherein a side surface of the convex ridge is provided with an opening.

13. The electric apparatus according to claim 12 , wherein the opening is located at a side of the convex ridge close to the battery cell.

14. A method for producing a battery, comprising following steps:
connecting a first insulating member to a fixing portion on an inner wall of a sleeve, so that the first insulating member is fixed to the fixing portion;
placing a battery cell into the sleeve;
connecting a second insulating member to the fixing portion, so that the second insulating member is fixed to the fixing portion, wherein the fixing portion is clamped to the first insulating member and the second insulating member;
wherein the first insulating member and the second insulating member are provided with a hook, and the hook is configured to clamp the groove of the fixing portion; and
utilizing a first end cover and a second end cover to seal both ends of the sleeve in a height direction respectively.
