Abstract

An adapter may include a first adapter and a second adapter disposed discretely. The first adapter may be configured to be connected to one of an electrode post or a tab. The second adapter may be configured to be connected to the other of the electrode post or the tab. The first adapter may substantially extend along a first direction. The second adapter may substantially extend along a second direction. The first direction may intersect the second direction. The first adapter may be connected to the second adapter by a conductive structure.

First claim

What is claimed is:

1 . A battery cell, comprising a shell, two electrode posts, an electrode assembly, and an adapter,
wherein the adapter comprises a first adapter and a second adapter disposed discretely, the first adapter is connected to one of the electrode posts, the second adapter is connected to a tab of the electrode assembly, the first adapter substantially extends along a first direction, the second adapter substantially extends along a second direction, the first direction intersects the second direction, and the first adapter is connected to the second adapter by a conductive structure, and wherein the shell comprises an accommodation cavity; the electrode assembly is accommodated in the accommodation cavity; the shell comprises a housing and an end cap; the housing is integrally formed; the housing comprises two first sidewalls disposed opposite to each other in the second direction and two second sidewalls disposed opposite to each other in a third direction; the two first sidewalls and the two second sidewalls close in to form the accommodation cavity; the housing comprises at least one opening in the first direction; the first direction, the second direction, and the third direction are perpendicular to one another; the electrode assembly comprises a body structure and the tab extending in the first direction from the body structure toward the opening; the two electrode posts are disposed to respectively pass through the two first sidewalls; the end cap is disposed at the opening to close the accommodation cavity; wherein the housing is filled with electrolyte.

2 . The battery cell according to claim 1 , wherein the tab comprises a positive tab and a negative tab, and the positive tab and the negative tab are disposed at a same end of the body structure.

3 . The battery cell according to claim 1 , wherein the two electrode posts are riveted or injection-molded to respectively pass through the two first sidewalls.

4 . A battery, comprising the battery cell according to claim 1 .

5 . An electrical device, comprising the battery according to claim 4 .

6 . The battery cell according to claim 1 , wherein the first adapter comprises a first main structure and a first connector disposed at an end of the first main structure, and the first main structure is connected to one of the electrode posts; and the first main structure extends along the first direction, the first connector extends along the second direction, and the first connector is connected to the second adapter.

7 . The battery cell according to claim 6 , wherein the second adapter comprises a second main structure and a second connector connected to the first connector, and the second main structure is connected to the tab, and the first connector extends toward a side close to the second main structure against the first main structure; or, the first connector extends toward a side away from the second main structure against the first main structure; or, in the second direction, the first connector extends toward both sides against the first main structure.

8 . The battery cell according to claim 6 , wherein the first connector and the first main structure are integrally formed.

9 . The battery cell according to claim 1 , wherein the conductive structure comprises a welding structure, a conductive adhesive bonding structure, a riveting structure, or a conductive element.
