1 . A case for a battery comprising:

a first case body provided with an opening;

an accommodating groove provided in a peripheral direction of the opening;

a sealant accommodated in the accommodating groove;

a holder arranged in the first case body wherein an inner peripheral wall of the first case body and the holder jointly define the accommodating groove;

a first locking member via which the holder is connected to the first case body; and

a second case body provided with a peripherally-arranged joint part wherein the joint part extends into the accommodating groove and is joined with the sealant,

wherein the second case body covers the opening so as to form a sealed connection between the first case body and the second case body,

wherein the holder comprises a stepped surface formed between a first peripheral surface and a second peripheral surface wherein the stepped surface is a bottom wall of the accommodating groove

wherein the joint part is provided with a notch for avoiding the first locking member and sealant completely covers the notch.

2 . The case according to claim 1 , wherein the joint part is configured to extend into the accommodating groove and be inserted into the sealant such that the joint part is joined with the sealant.

3 . The case according to claim 1 , wherein the accommodating groove is located on an inner side of the first case body.

4 . The case according to claim 1 , wherein the holder is provided with a limiting portion and the limiting portion is configured to abut against a battery unit located in the first case body to limit a movement of the battery unit in a direction approaching the second case body.

6 . The case according to claim 1 , wherein the first case body is provided with a first mounting hole and the holder is provided with a second mounting hole and the first locking member sequentially passes through the first mounting hole, the sealant, and the second mounting hole to connect the holder to the first case body.

7 . The case according to claim 1 , wherein an outer peripheral wall of the holder comprises: the first peripheral surface attached to the inner peripheral wall of the first case body and the second peripheral surface arranged spaced apart from the inner peripheral wall of the first case body wherein the second peripheral surface is one side wall of the accommodating groove and the inner peripheral wall of the first case body is the other side wall of the accommodating groove.

8 . The case according to claim 1 , further comprising a second locking member via which the second case body is connected to the first case body.

9 . The case according to claim 8 , wherein the first case body is provided with a third mounting hole and the second case body is provided with a fourth mounting hole and the second locking member sequentially passes through the third mounting hole and the fourth mounting hole to connect the first case body to the second case body wherein the third mounting hole is closer to the opening than the sealant.

10 . A battery comprising:

a case according to claim 1 ; and
