The second insulating part 122 extending in the second direction Y can fix the plurality of battery cells 20 arranged in the second direction Y in a group while playing an insulating role, improving assembly efficiency. During the use of the battery 10, the plurality of battery cells 20 are fixed as a whole by the second insulating portion 122, so that the reliability and the service life of the battery 10 can be improved. Meanwhile, at least part of the second insulating part 122 is made of transparent material, so that the fixed connection between the second insulating part 122 and the battery cell 20 is easily observed and controlled, and therefore, the technological parameters for preparing the battery 10 can be timely adjusted, and the production efficiency of the battery 10 is improved.

Optionally, according to some embodiments of the present application, the second insulating portion 122 is fixedly connected to two adjacent groups of the battery cells 20 arranged along the second direction Y.

The second insulating part 122 may be fixedly connected with two adjacent groups of the battery cells 20 arranged in the second direction Y at the same time, and then each two adjacent groups of the battery cells 20 arranged in the second direction Y corresponds to one second insulating part 122, in which case the second insulating part 122 may cover at least part of the gap between the two adjacent battery cells 20 arranged in the first direction X.

According to some embodiments of the present application, optionally, the insulating member 12 includes a first insulating part 121, a second insulating part 122, and a connecting part 123, and the first insulating part 121 extends along the first direction X and is fixedly connected with the plurality of battery cells 20 arranged along the first direction X. The second insulating part 122 extends in the second direction Y and is fixedly connected to the plurality of battery cells 20 arranged in the second direction Y, and the connection part 123 is used to connect the first insulating part 121 and the second insulating part 122.

Fig. 7 and 8 show the structure of an insulating member 12 provided in the embodiment of the present application, wherein fig. 8 is an enlarged schematic view of a portion a in fig. 7. In fig. 7 and 8, the first insulating portion 121 extends along the first direction X, the second insulating portion 122 extends along the second direction Y, and the first insulating portion 121 and the second insulating portion 122 are connected to each other to form a mesh structure, in which a structure for filling at least a partial area of the mesh is the connection portion 123. Specifically, at least one of both ends of the connection portion 123 in the first direction X is connected to the second insulating portion 122, and at least one of both ends in the second direction Y is connected to the first insulating portion 121.

The connecting portion 123 can improve the strength and stability of the insulating member 12, increase the coverage area of the insulating member 12 to the battery cell 20, realize insulation in a larger range, and further improve the insulation effect of the insulating member 12.

Optionally, according to some embodiments of the present application, at least part of the connecting portion 123 is made of transparent material.

In some embodiments, a light-transmitting region may be provided at least in a partial region of the first insulating part 121 and the second insulating part 122 at the same time. Alternatively, a light-transmitting region may be disposed in at least a partial region of the connection portion 123, that is, a portion of the connection portion 123 made of a transparent material.

In order to improve the connection strength between the insulating member 12 and the battery cell 20, the connection portion 123 may be bonded to the battery cell 20. In the case where the connection portion 123 needs to be coated with the adhesive material, the region of the connection portion 123 that needs to be coated with the adhesive material may be set as a light-transmitting region; in the case where the adhesive material needs to be applied to a partial region of the battery cell 20, a region where the connection part 123 is adhered to the battery cell 20 by the adhesive material may be set as a light-transmitting region.

The fixed connection between the insulating piece 12 and the battery cell 20 is conveniently observed and controlled, the accuracy of the coating position of the bonding material is conveniently improved, the coating amount of the bonding material can be controlled according to actual conditions, on one hand, the connection strength between the insulating piece 12 and the battery cell 20 can be improved, and on the other hand, the possibility of overflowing of the bonding material can be reduced.

Optionally, according to some embodiments of the present application, the portion of the insulating member 12 that is transparent has a light transmittance of greater than or equal to 20% and less than or equal to 100%. Transmittance refers to the percentage of light flux transmitted through an object to its incident light flux, and can be measured, typically using a spectrophotometer. Alternatively, the portion of the insulating member 12 that is transparent may have a light transmittance of 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%.

In order to better observe the other side of the insulating member 12 from the one side of the insulating member 12, the light transmittance of the transparent material portion of the insulating member 12 may be greater than or equal to 20% and less than or equal to 100%, so that light can be effectively transmitted, and it is advantageous to observe the condition of the other side of the insulating member from the one side of the insulating member 12. The light transmittance can show the ability of light to penetrate through the transparent material, and too small light transmittance can make the transparency of the insulating member insufficient, and light is difficult to penetrate through the transparent material part of the insulating member 12, so that the process of the battery 10 is not easy to observe and control.

Optionally, according to some embodiments of the present application, the battery 10 includes an adhesive layer for adhering the insulator 12 to the battery cell 20.

The insulating member 12 is disposed on one side of the plurality of battery cells 20 along the third direction Z, and the insulating member 12 and the battery cells 20 may be fixedly connected by adhesion, and the structure formed by the adhesive material is an adhesive layer.

The bonding layer can be used for fixedly connecting the insulating piece 12 with the battery cell 20, so that the connection strength between the insulating piece 12 and the battery cell 20 is improved.

Optionally, according to some embodiments of the present application, the material of the adhesive layer comprises a photosensitive adhesive.

Photosensitive adhesives refer to a type of adhesive material that can be cured by absorbing light of a specific wavelength, for example, UV adhesives (Ultraviolet Rays Glue, UV curable adhesives) can be converted from a liquid state to a solid state in a short period of time after absorbing UV light under irradiation of UV light.

In the embodiment of the present application, the photosensitive adhesive may be coated on the transparent area of the insulating member 12, that is, the portion of the insulating member 12 made of transparent material. Specifically, the photosensitive adhesive may be coated on a side of the light-transmitting area on the insulating member 12, which faces the battery cell 20, so that when the insulating member 12 is connected with the battery cell 20 through the photosensitive adhesive, light can be applied to the photosensitive adhesive from a side of the light-transmitting area on the insulating member 12, which faces away from the battery cell 20, so that the photosensitive adhesive can be solidified under the light condition, and an adhesive layer is formed between the insulating member 12 and the battery cell 20, thereby realizing the fixed connection between the insulating member 12 and the battery cell 20.

The photosensitive adhesive can accelerate the solidification speed under the illumination condition, reduce the production period and improve the production efficiency. Meanwhile, the photosensitive adhesive can be matched with a light-transmitting area on the insulating piece 12, so that the photosensitive adhesive can receive illumination to realize rapid solidification.

According to some embodiments of the present application, optionally, the battery cell 20 includes an electrode terminal 21, and the insulating member 12 is provided with a first through hole 1231, and the first through hole 1231 is used to avoid the electrode terminal 21.

As shown in fig. 11 and 12, a first through hole 1231 may be provided at the connection part 123, penetrating the connection part 123 in the third direction Z. The third direction Z is perpendicular to a plane formed by the first direction X and the second direction Y, and may refer to a thickness direction of the insulator 12.

The electrode terminals 21 are structures in the battery cells 20 for drawing electric energy inside the battery cells 20 to the outside of the battery cells 20, and may be connected to an electric device so that the battery cells 20 can supply electric energy. The battery cell 20 may include two electrode terminals 21, a positive electrode terminal 21 and a negative electrode terminal 21, respectively.

The first through holes 1231 are provided corresponding to the electrode terminals 21, and alternatively, each of the first through holes 1231 on the insulating member 12 may correspond to one electrode terminal 21. The first through hole 1231 can escape the electrode terminal 21 such that the electrode terminal 21 and the insulator 12 do not interfere with each other.

Fig. 11 shows an assembled structure of the insulating member 12 and the battery cell 20, and fig. 12 is an enlarged schematic view of a portion B in fig. 11. As shown in fig. 11 and 12, at least a portion of the electrode terminal 21 may be received in the first through hole 1231, and the electrode terminal 21 may be electrically connected between the different battery cells 20 through the bus member 22 without being covered with the insulating member 12 at the position where the electrode terminal 21 is located.

The first through holes 1231 can reduce interference between the electrode terminals 21 and the insulator 12, so that the electrode terminals 21 can achieve electrical connection between the different battery cells 20 through the bus member 22. Meanwhile, the mutual matching between the first through holes 1231 and the electrode terminals 21 can also play a role in positioning the position of the insulating member 12 in the battery 10, which is advantageous in improving the accuracy of the assembly position of the insulating member 12.

According to some embodiments of the present application, optionally, the insulating member 12 is provided with a first blocking portion 1261 protruding from a surface of the insulating member 12 facing the battery cell 20, and the first blocking portion 1261 is disposed around the first through hole 1231.

As shown in fig. 9 to 12, a first blocking portion 1261 may be provided around the first through hole 1231. The first blocking portion 1261 protrudes from a surface of the insulating member 12 facing the battery cell 20, and in particular, may protrude from a surface of the connection portion 123 facing the battery cell 20. For example, the first barrier 1261 may be annular and surround the first through hole 1231, alternatively, the first barrier 1261 may surround the first through hole 1231 along an edge of the first through hole 1231. Alternatively, the sidewall of the inner ring of the first blocking portion 1261 may be coplanar with the wall of the first through hole 1231. In one possible embodiment, a first barrier 1261 may be provided around each first through hole 1231. Alternatively, the first blocking portion 1261 may be integrally formed with the insulating member 12. Alternatively, the first blocking portion 1261 may be a sealing tape or a foaming adhesive provided on the surface of the insulating member 12 facing the battery cell 20.

In some embodiments, the surface of the insulating member 12 facing the battery cell 20 may be coated with an adhesive material to achieve adhesion between the insulating member 12 and the battery cell 20, so that in the case that the connecting portion 123 needs to be coated with the adhesive material, the first blocking portion 1261 can limit the flow of the adhesive material to the first through hole 1231, reduce the possibility that the adhesive material attached to the surface of the connecting portion 123 contacts the electrode terminal 21 in the first through hole 1231, and reduce the influence of the adhesive material on the connection between the bus member 22 and the electrode terminal 21. In some embodiments, the first barrier 1261 can act as a barrier to solid particles, e.g., the first barrier 1261 can reduce the likelihood of metal particles coming into contact with the electrode terminal 21, reducing the probability of shorting of the battery 10.

The first blocking portion 1261 may protect the electrode terminal 21 in the first through hole 1231, may restrict the flow of the adhesive to the electrode terminal 21, and may reduce the possibility that the adhesive attached to the surface of the connection portion 123 contacts the electrode terminal 21, thereby reducing the influence of the adhesive on the connection between the bus member 22 and the electrode terminal 21. Meanwhile, the first blocking part 1261 can play a certain role in blocking solid particles, particularly metal particles, so that the probability of short circuit of the battery 10 can be reduced, and the reliability of the battery 10 can be improved.

Optionally, according to some embodiments of the present application, the first blocking portion 1261 abuts against a surface of the battery cell 20 facing the insulator 12.

In the third direction Z, the surface of the first blocking portion 1261 facing the battery cell 20 contacts the surface of the battery cell 20 facing the insulator 12. Alternatively, the first blocking portion 1261 may be made of an elastic material, and may be compressed to a certain extent during the assembly of the battery 10 to improve the sealing degree between the first blocking portion 1261 and the battery cell 20, thereby improving the blocking effect of the first blocking portion 1261 on the adhesive material or the solid particles.

The surface contact between the first blocking portion 1261 and the battery cell 20 can improve the sealing effect of the first blocking portion 1261 on the surrounding area of the first through hole 1231, and further plays a role in blocking the adhesive material or the solid particles, so that the influence of the adhesive material on the connection between the bus member 22 and the electrode terminal 21 is reduced, and meanwhile, a certain blocking effect can be further played on the solid particles, particularly the metal particles, so that the probability of short circuit of the battery 10 can be reduced, and the reliability of the battery 10 is improved.

Optionally, according to some embodiments of the present application, the battery cell 20 includes a pressure relief mechanism 23, and the connecting portion 123 is provided with a second through hole 1232, and the second through hole 1232 is used to avoid the pressure relief mechanism 23.

The pressure release mechanism 23 refers to an element or component that is actuated to release the internal pressure when the internal pressure or temperature of the battery cell 20 reaches a predetermined threshold. Wherein, "actuation" refers to the actuation of the pressure release mechanism 23, such that the internal pressure and temperature of the battery cell 20 are released. The actions generated by the pressure relief mechanism 23 may include, but are not limited to: at least a portion of the pressure relief mechanism 23 breaks, tears, melts, etc. Upon actuation of the pressure release mechanism 23, the high temperature and high pressure material inside the battery cell 20 may be discharged as a discharge from the pressure release mechanism 23. The predetermined threshold may be adjusted according to design requirements. The predetermined threshold may depend on the material of one or more of the positive electrode tab, the negative electrode tab, the electrolyte, and the separator in the battery cell 20. The pressure relief mechanism 23 may employ an element or component such as being pressure sensitive or temperature sensitive, i.e., when the internal pressure or temperature of the battery cell 20 reaches a predetermined threshold, the pressure relief mechanism 23 is actuated, thereby forming a channel through which the internal pressure may be vented. Emissions from the battery cell 20 include, but are not limited to: electrolyte, dissolved or split positive and negative electrode plates, fragments of a separator, high-temperature and high-pressure gas generated by reaction, flame, and the like.

The pressure release mechanism 23 on the battery cell 20 has an important influence on the reliability of the battery 10. For example, when the battery cell 20 is short-circuited, overcharged, etc., thermal runaway may occur inside the battery cell 20 and thus the pressure or temperature may rise suddenly. Actuation by pressure relief mechanism 23 in this case may release the internal pressure and temperature outwardly to reduce the likelihood of explosion and fire of cell 20.

As shown in fig. 9 to 12, the second through hole 1232 may be provided at the connection part 123, penetrating the connection part 123 in the third direction Z. The second through holes 1232 may be provided corresponding to the pressure release mechanisms 23, alternatively, each pressure release mechanism 23 on the insulating member 12 may correspond to one second through hole 1232. Avoiding the pressure release mechanism 23 by the second through hole 1232 means that the second through hole 1232 may reserve a certain space for the actuation of the pressure release mechanism 23, so that the pressure release mechanism 23 can release the internal pressure and temperature by using the space. As shown in fig. 11 and 12, in some embodiments, the receiving space formed by the second through hole 1232 may provide room for actuation of the pressure relief mechanism 23. Alternatively, at least part of the pressure release mechanism 23 may also be accommodated in the second through hole 1232.

The second through hole 1232 can provide a space for avoiding actuation of the pressure release mechanism 23, and when the internal pressure or temperature of the battery cell 20 reaches a predetermined threshold, the pressure release mechanism 23 is more easily actuated to reduce the possibility of explosion and fire of the battery cell 20.

According to some embodiments of the present application, the insulating member 12 is optionally provided with a second blocking portion 1262 protruding from a surface of the insulating member 12 facing the battery cell 20, the second blocking portion 1262 being disposed around the second through hole 1232.

As shown in fig. 9 to 12, a second blocking portion 1262 may be provided around the second through hole 1232. The second blocking portion 1262 protrudes from a surface of the insulating member 12 facing the battery cell 20, and in particular, may protrude from a surface of the connection portion 123 facing the battery cell 20. For example, the second barrier 1262 may be annular and surround the first through hole 1231, alternatively, the second barrier 1262 may surround the second through hole 1232 along an edge of the second through hole 1232. Alternatively, the sidewall of the inner ring of the second blocking portion 1262 may be coplanar with the wall of the second through hole 1232. In one possible embodiment, a second barrier 1262 may be provided around each second through hole 1232. Alternatively, the second blocking portion 1262 may be integrally formed with the insulator 12. Alternatively, the second blocking portion 1262 may be a sealing tape or a foaming adhesive provided on the surface of the insulating member 12 facing the battery cell 20.

In some embodiments, the surface of the insulating member 12 facing the battery cell 20 may be coated with an adhesive material to achieve adhesion between the insulating member 12 and the battery cell 20, and if the connecting portion 123 needs to be coated with the adhesive material, the second blocking portion 1262 can limit the flow of the adhesive material to the second through hole 1232, so as to reduce the possibility that the adhesive material attached to the surface of the connecting portion 123 contacts the pressure release mechanism 23 in the second through hole 1232. In some embodiments, the second barrier 1262 can act as a barrier to solid particulates, e.g., the second barrier 1262 can reduce the likelihood of solid particulates coming into contact with the pressure relief mechanism 23, reducing the probability of damage to the pressure relief mechanism 23.

The second blocking portion 1262 can protect the pressure release mechanism 23 in the second through hole 1232, can limit the flow of the adhesive material to the pressure release mechanism 23, reduces the possibility that the adhesive material attached to the surface of the insulating member 12 contacts the pressure release mechanism 23, reduces the possibility that the pressure release mechanism 23 is stuck and is difficult to actuate, and improves the reliability of the battery 10. At the same time, the second blocking portion 1262 can play a role in blocking solid particles, so that the possibility of damage of the pressure release mechanism 23 can be reduced, and the reliability of the battery 10 can be improved.

Optionally, according to some embodiments of the present application, the second barrier 1262 abuts a surface of the battery cell 20 facing the insulator 12.

In the third direction Z, the surface of the second blocking portion 1262 facing the battery cell 20 contacts the surface of the battery cell 20 facing the insulator 12. Alternatively, the second blocking portion 1262 may be made of an elastic material, and may be compressed to a certain extent during the assembly of the battery 10 to improve the sealing degree between the second blocking portion 1262 and the battery cell 20, thereby improving the blocking effect of the second blocking portion 1262 on the adhesive material or the solid particles.

The surface contact between the second blocking part 1262 and the battery cell 20 can improve the sealing effect of the second blocking part 1262 on the surrounding area of the second through hole 1232, and further plays a role in blocking the adhesive material or the solid particles, so that the influence of the adhesive material or the solid particles on the pressure release mechanism 23 is reduced, and the reliability of the battery 10 is improved.

Specifically, the battery 10 provided in the embodiment of the present application is provided with the light-transmitting area on the insulating member 12, and the process of the battery 10 can be observed and controlled through the light-transmitting area, which is favorable for improving the reliability of the battery 10, so that the reliability of the power utilization device can be improved when the battery 10 provides electric energy for the power utilization device.
