a patch 4 attached to the housing 1, and a projection of the patch 4 toward the housing 1 is adapted to cover the explosion-proof valve 12;
an insulating film 3 that covers the outer peripheral side of the housing 1, and the patch 4 is located between the explosion-proof valve 12 and the insulating film 3.
According to the battery provided by the embodiment, the patch 4 is attached to the shell 1, so that the projection of the patch 4 towards the shell 1 covers the explosion-proof valve 12, after the patch 4 is covered, the insulating film 3 is coated on the outer peripheral side of the shell 1, and the patch 4 is positioned between the explosion-proof valve 12 and the insulating film 3, so that after the insulating film 3 is coated, the patch 4 is added, and then the cutting is performed according to marks of the patch 4, so that the explosion-proof valve is exposed outside, namely, the situation that the position of a cutting hole of the insulating film corresponding to the explosion-proof valve is cut on the insulating film before the insulating film is coated, the situation that the position of the cutting hole of the insulating film cannot effectively correspond to the explosion-proof valve is avoided, and the situation that the explosion-proof valve is cut and damaged by a cutting tool caused when the insulating film is coated and then cut is avoided. Thereby ensuring that the cutting position on the insulating film 3 can be right opposite to the explosion-proof valve 12 and ensuring that the explosion-proof valve 12 is intact.
Alternatively, the patch 4 may be made of plastic.
Specifically, a cutting area 31 is formed on the insulating film 3, and the cutting area 31 is cut by the insulating film 3 at a position corresponding to the patch 4.
In a specific cutting process, the insulating film 3 can be cut by the nicking tool compared with the outer edge of the patch 4, and when the cutting process is performed, the nicking tool can scratch through the insulating film 3, but the nicking tool can scratch through the insulating film 3 and cannot scratch through the patch 4 only because the patch 4 is arranged between the insulating film 3 and the explosion-proof valve 12, so that the damage of the nicking tool to the explosion-proof valve 12 is avoided.

By making the area of the cutting area 31 smaller than or equal to the area of the patch 4, it is possible to ensure that scratches of the cutting area 31 fall on the patch 4, and to avoid damage to the explosion-proof valve 12 caused by the scratches falling on an area other than the patch 4.
Specifically, the edge of the cut-out 31 matches the shape of the edge of the patch 4. By matching the score with the edge shape of the patch 4, it is ensured that the cutting area 31 is smoothly cut down, and that the score falls on the patch 4.
In particular, the patch 4 is adapted to be taken out from the position of the cutting zone 31. After the insulating film 3 is cut, the insulating film corresponding to the cutting area 31 may be removed, at this time, a notch is formed on the insulating film 3, the corresponding patch 4 is in an exposed state, and the patch 4 may be taken out from the notch, so as to ensure that the patch 4 yields to the position of the explosion-proof valve 12, and the notch formed on the insulating film 3 may correspond to the position of the explosion-proof valve 12.
Specifically, the casing 1 is provided with at least one explosion-proof valve 12, and the patch 4 is attached to the position of each explosion-proof valve 12.
Alternatively, a plurality of the explosion-proof valves 12, for example, two or three or more, may be provided on the housing 1. Before the insulating film 3 is coated on the outer peripheral side of the housing 1, the patch 4 may be attached to each position of the explosion-proof valve 12, so that after the insulating film 3 is completed, the position corresponding to each explosion-proof valve 12 may be cut, so as to ensure that the notch formed on the insulating film 3 can correspond to the position of the explosion-proof valve 12, and due to the patch 4, the situation that the explosion-proof valve is cut and damaged by a cutting tool in the cutting process can be avoided.
Specifically, at least one side of the housing 1 in the height direction forms a narrow side region 11, and the explosion-proof valve 12 is disposed on the narrow side region 11.
As shown in fig. 1, the battery of this embodiment may be a strip-shaped battery, a narrow side area 11 is formed on at least one side of the housing 1 along the height direction, and the explosion-proof valve 12 is disposed on the narrow side area 11.
In particular, the patch 4 is glued to the narrow-sided region 11 and/or the explosion-proof valve 12.
The patch 4 is fixed in a sticking mode, and when the patch is stuck, the patch 4 can be stuck on the edge of the narrow side area 11 corresponding to the explosion-proof valve 12, and the patch 4 can be stuck on the explosion-proof valve 12.
Specifically, the narrow side area 11 is protruded in the height direction around the area of the explosion-proof valve 12 to form a protruding portion, and the patch 4 is adhered to the upper surface of the protruding portion.
According to the battery provided by the embodiment, the convex part is formed in the area of the narrow side area 11 surrounding the explosion-proof valve 12 in the protruding mode along the height direction, and the patch 4 is adhered to the upper surface of the convex part, so that the nicking tool can be ensured to be in contact with the convex part only when the area of the explosion-proof valve 12 is cut, the acting force of the nicking tool is prevented from acting on the explosion-proof valve 12, and the safety of the explosion-proof valve 12 is ensured.
In addition, due to the existence of the protruding part, in the process of filling the battery, electrolyte can be prevented from flowing into the explosion-proof valve 12, the protruding part plays a role in blocking, corrosion to the explosion-proof valve 12 is avoided, and normal use of the explosion-proof valve 12 is ensured.
