2 . The battery according to claim 1 , wherein an extension face of the first output end and an extension face of the second output end are disposed parallel to each other.

3 . The battery according to claim 2 , wherein an angle between the extension face of the first output end and the first input end is in a range of 80-120°;
and/or, an angle between the extension face of the second output end and the second input end is in a range of 80-120°.

4 . The battery according to claim 1 , wherein a height of the first output end protruding away from the end face of the battery body is the same as a height of the second output end protruding away from the end face of the battery body.

5 . The battery according to claim 2 , wherein the second electrode adapter sheet further comprises a positioning portion, the positioning portion is connected with at least one of the second input end and the second output end, and at least part of the positioning portion protrudes away from a side wall of the battery body;
wherein the positioning portion comprises a first sub-portion and a second sub-portion, the first sub-portion extends along the side wall of the battery body, and a first end of the first sub-portion is connected to the second input end and/or the second output end, a second end of the first sub-portion is connected to the second sub-portion; the second sub-portion extends to a direction facing away from the side wall of the battery body and protrudes away from the side wall of the battery body.

6 . The battery according to claim 5 , wherein a distance between the second sub-portion and a first end of the battery body is a first distance, a distance between the second sub-portion and a second end of the battery body is a second distance, and the first distance is greater than the second distance.

7 . The battery according to claim 5 , wherein the first output end and the second output end are spaced and parallelly disposed at the first end of the battery body, and a gap between the first output end and the second output end is opposite to the positioning portion.
wherein the first output end and the second output end are symmetrically distributed at two sides of a first plane respectively, a symmetric plane of the positioning portion along a radial direction of the battery body is a second plane, and an angle between the second plane and the first plane is greater than or equal to 0°, and less than or equal to 10°.

8 .
