[0051] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0052] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as those commonly understood by technicians in the technical field of this application; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned drawings and any variations thereof are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary and secondary relationship.

[0053] Reference to "embodiment" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

[0054] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "attached" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0055] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the associated objects before and after are in an "or" relationship.

[0056] In the embodiments of the present application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only exemplary descriptions and should not constitute any limitation to the present application.

[0057] The term "plurality" used in the present application refers to two or more (including two).

[0058] In the related technologies of perovskite solar cells, a substrate is used as a base, a hole transport layer is formed on the substrate, the hole transport layer is laser processed, and then a perovskite layer is formed on the hole transport layer. Usually, a hole transport layer is formed on a substrate by a coating device, and after unloading from the coating device, it needs to be transported by a conveying mechanism, and then laser processed in a laser scribing device. However, the temperature of the substrate after unloading from the coating device is too high. Due to the influence of thermal stress, some line segments are bent after laser scribing, thereby increasing the dead zone area; although the substrate can be naturally cooled after unloading, the cleaning effect becomes worse after laser scribing, which is not conducive to the formation of the perovskite layer and reduces the reliability of the perovskite solar cell. The above statements are only used to provide background technical information related to the present application and do not necessarily constitute prior art.

[0059] In view of the above problems, the battery production equipment provided by this application, by setting up a heat exchange component and integrating the heat exchange component on the transmission path of the substrate, not only realizes the normal transportation of the substrate, but also realizes the cooling of the substrate, reduces the impact of thermal stress in the next process, and shortens or cancels the placement time of the substrate before entering the next process. Moreover, after the substrate is transported by the conveying mechanism, the value of the water drop angle of the substrate is reduced, and the wettability of the substrate is improved, thereby improving the stability of the formation of the perovskite layer, and then improving the reliability of the perovskite solar cell.

[0060] The battery production equipment disclosed in the present application can be used to manufacture solar cells, and the solar cells can be but are not limited to perovskite solar cells. At the same time, the battery disclosed in the present application can be used in but is not limited to electrical devices such as vehicles, ships or aircraft. A power supply system comprising the battery disclosed in the present application can be used to form the electrical device.

[0061] See also Figure 1 , Figure 1 It is a structural diagram provided by an embodiment of the present application.

[0062] like Figure 1 As shown, the present application proposes a battery production device 100, which includes a support 10, a conveying mechanism 20 and a heat exchange component 30. The conveying mechanism 20 is arranged on the support 10, and is used to receive and convey the substrate 1. The heat exchange component 30 is arranged on the support 10 and is located on the transmission path of the substrate 1. The heat exchange component 30 is used to exchange heat with the substrate 1.

[0063] In order to enable the solar cell to have a certain structural strength, the solar cell uses the substrate 1 as a base, and other layers such as the transmission layer are arranged on the substrate 1 .

[0064] The substrate 1 may also be referred to as a substrate. The material of the substrate 1 may be, but is not limited to, glass, tempered glass, quartz, organic flexible materials, etc.; of course, it may also be transparent conductive glass, stainless steel conductive flexible substrate, polyethylene glycol terephthalate (PET) conductive flexible substrate, etc.

[0065] Specifically, the battery production equipment 100 also includes a coating device. After the substrate 1 is unloaded from the coating device, it is placed on the conveying mechanism 20 for transmission to the next process.

[0066] The bracket 10 is used as the basic component of the battery production equipment 100 to install and carry other components, such as the conveying mechanism 20 and the heat exchange component 30. The bracket 10 can have a variety of shapes, regular shapes such as a cuboid, a cube, a cylinder, etc., or other irregular shapes. The shape of the bracket 10 should not affect the normal conveying of the conveying mechanism 20 and the cooling of the substrate 1 by the heat exchange component 30. This application does not limit the specific shape of the bracket 10. The bracket 10 can also be made of a variety of materials, such as steel, aluminum alloy, or other composite materials.

[0067] The conveying mechanism 20 is used to receive the substrate 1 and convey the substrate 1 to a downstream device.

[0068] In an embodiment of the present application, the conveying mechanism 20 may include one conveying channel or multiple conveying channels. When including multiple conveying channels, the conveying paths of each conveying channel may be the same or different to achieve synchronous conveyance of multiple substrates 1 to speed up the conveyance of multiple substrates 1.

[0069] For example, the conveying mechanism 20 may include gear transmission, chain transmission, belt transmission, shaft transmission, etc.

[0070] The heat exchange component 30 is used to exchange heat with the substrate 1 to achieve the purpose of adjusting the temperature.

[0071] Specifically, the heat exchange component 30 is located on the transmission path of the substrate 1, and performs heat exchange on the substrate 1 on the conveying mechanism 20. The heat exchange component 30 can be fixed to the bracket 10 to cool the substrate 1 passing through the heat exchange component 30; or, the heat exchange component 30 can be movably arranged on the bracket 10 to move along the transmission path of the substrate 1, so as to continuously cool the substrate 1 on the conveying mechanism 20; or, the heat exchange component 30 can be temporarily attached to the surface of the substrate 1 to cool the substrate 1, and at this time, the substrate 1 can be temporarily in a stationary state or in a moving state.

[0072] Exemplarily, the heat exchange component 30 uses a heat exchange pipeline, which is used to guide the flow of heat exchange medium. The heat exchange medium flowing in the heat exchange pipeline can quickly take away heat.

[0073] Exemplarily, the heat exchange component 30 is a surface cooler.

[0074] The battery production equipment 100 provided in the present application, by providing a heat exchange component 30, and integrating the heat exchange component 30 on the transmission path of the substrate 1, realizes both the normal transportation of the substrate 1 and the cooling of the substrate 1, reduces the influence of thermal stress of the next process, and shortens or cancels the placement time of the substrate 1 before entering the next process. Moreover, after the substrate 1 is transported by the conveying mechanism 20, the value of the water drop angle of the substrate 1 is reduced, and the wettability of the substrate 1 is improved, thereby improving the stability of the formation of the perovskite layer, and then improving the reliability of the perovskite solar cell.

[0075] Combined participation Figure 2 and Figure 3 , Figure 2 It is a structural schematic diagram of a battery production device provided in one embodiment of the present application; Figure 3 It is a front view of a battery production device provided in one embodiment of the present application.

[0076] According to one embodiment of the present application, Figure 2 and Figure 3 As shown, the heat exchange assembly 30 is at least arranged on both sides of the conveying mechanism 20 along the first direction x, and the first direction x, the conveying direction y of the substrate 1 and the vertical direction z of the bracket 10 are perpendicular to each other.

[0077] In the embodiment of the present application, the battery production equipment 100 includes at least two heat exchange components 30 , and the two heat exchange components 30 are respectively arranged on both sides of the conveying mechanism 20 along the first direction x.

[0078] Specifically, the projection of the conveying mechanism 20 along the vertical direction z of the bracket 10 falls into the substrate 1. It can be understood that the area of ​​the conveying mechanism 20 is smaller than the area of ​​the substrate 1, so as to increase the contact area or overlapping area between the heat exchange component 30 and the substrate 1, thereby increasing the heat exchange area.

[0079] Optionally, along the vertical direction z of the bracket 10 , the heat exchange assembly 30 at least partially overlaps with the base plate 1 .

[0080] In these optional embodiments, such an arrangement can increase the area of ​​the heat exchange component 30 corresponding to the substrate 1, thereby improving the heat exchange efficiency.

[0081] According to an embodiment of the present application, the conveying mechanism 20 includes a plurality of conveying belts 21 arranged at intervals along the first direction x, and the heat exchange assembly 30 is further arranged between two adjacent conveying belts 21 .

[0082] Specifically, the conveying mechanism 20 includes N conveying belts 21 arranged at intervals along the first direction x, and the battery production equipment 100 includes N+1 conveying mechanisms 20. Each conveying belt 21 is provided with a conveying mechanism 20 on both sides along the first direction x. It can be understood that in the first direction x, the conveying belt 21 and the heat exchange assembly 30 are staggered along the first direction x. Each conveying belt 21 can convey a substrate 1 alone, or multiple conveying belts 21 can convey a substrate 1 together.

[0083] Exemplarily, the conveying mechanism 20 includes a first conveying belt and a second conveying belt spaced apart along a first direction x, and the substrate 1 is configured to be transported on the first conveying belt and the second conveying belt.

[0084] Optionally, the conveying mechanism 20 extends along the transport direction y of the substrate 1 .

[0085] In these optional embodiments, such a configuration can increase the density of the heat exchange component 30 in the area opposite to the substrate 1, so that the heat released by the substrate 1 can be quickly transferred to the heat exchange component 30, with a higher heat transfer efficiency, thereby improving the cooling efficiency.

[0086] According to one embodiment of the present application, Figure 2 and Figure 3 As shown, the heat exchange component 30 has a heat exchange plane 31 on its upper side, and the heat exchange plane 31 is configured to be attached to the substrate 1 .

[0087] In the embodiment of the present application, the upper side of the heat exchange component 30 has a heat exchange plane 31, and the heat exchange plane 31 can be attached to the substrate 1 to increase the contact area between the heat exchange component 30 and the substrate 1. Optionally, during the process of attaching the heat exchange plane 31 of the heat exchange component 30 to the substrate 1, the conveying of the substrate 1 can be suspended, and after the temperature of the substrate 1 drops to a preset temperature, the heat exchange component 30 is separated from the substrate 1, and the conveying mechanism 20 continues to convey the substrate 1.

[0088] Optionally, the substrate 1 has a first surface and a second surface opposite to each other along the thickness direction, the second surface is located at the lower side and is a plane, and the heat exchange plane 31 on the upper side of the heat exchange component 30 is in contact with the second surface.

[0089] In these optional embodiments, the heat exchange component 30 has a heat exchange plane 31 on its upper side, so that the heat exchange component 30 has a larger contact area with the substrate 1, thereby improving the heat transfer efficiency.

[0090] According to an embodiment of the present application, the heat exchange assembly 30 includes a heat exchange plate 32 , in which a flow channel 321 is provided. The flow channel 321 is used to guide the flow of a heat exchange medium.

[0091] A flow channel 321 is provided inside the heat exchange plate 32, and the flow channel 321 is used to guide the flow of the heat exchange medium. The heat exchange medium flowing in the flow channel 321 can quickly take away the heat of the substrate 1. The heat exchange medium is a fluid medium, for example, including water, ethanol, oil and Freon. The heat exchange medium can absorb the heat of the substrate 1, or the flowing heat exchange medium can take away the heat of the substrate 1 to the external environment to achieve the purpose of cooling.

[0092] Exemplarily, the heat exchange plate 32 includes a first plate body and a second plate body, the first plate body and the second plate body are stacked along the thickness direction of the heat exchange plate 32, the first plate body is provided with a guide groove, the second plate body has a first surface and a second surface arranged oppositely along the thickness direction, the first surface is used to contact the substrate 1, and the second surface is connected to the first plate body and covers the guide groove to enclose and form the flow channel 321. In this way, the guide groove can be directly processed and manufactured on the semi-finished first plate body, simplifying the structure of the flow channel 321.

[0093] In some embodiments, the flow channel 321 may be wavy, toothed, S-shaped, etc.

[0094] Optionally, the heat exchange assembly 30 includes a heat exchange plate 32, and a surface of the heat exchange plate 32 facing the substrate 1 is a plane.

[0095] In these optional embodiments, the flow channel 321 can guide the flow of the heat exchange medium to quickly remove the heat of the substrate 1 and achieve continuous cooling of the substrate 1 .

[0096] According to an embodiment of the present application, the heat exchange assembly 30 further includes a joint, which is disposed on the heat exchange plate 32 and communicates with the flow channel 321 .

[0097] In the embodiment of the present application, the heat exchange component 30 includes a heat exchange plate 32 and a joint. The heat exchange plate 32 is provided with a flow channel 321. The joint is arranged on the heat exchange plate 32 and is connected with the flow channel 321. The flowing heat exchange medium flows into or out of the flow channel 321 through the joint. The heat exchange medium flows in the flow channel 321 and absorbs part of the heat through heat exchange, thereby realizing cooling of the substrate 1.

[0098] Exemplarily, the heat exchange component 30 includes a joint, through which the heat exchange medium can be introduced into the flow channel 321, and the heat exchange medium in the flow channel 321 can also be discharged through the joint.

[0099] Exemplarily, the heat exchange assembly 30 includes multiple joints, at least one of the multiple joints is used to guide the heat exchange medium into the flow channel 321, and at least one joint is used to export the heat exchange medium in the flow channel 321, wherein the multiple joints can be arranged at one end of the heat exchange plate 32, or the multiple joints can be respectively arranged at both ends of the heat exchange plate 32.

[0100] In these optional embodiments, the joint is connected to the heat exchange plate 32, which facilitates installation and removal of the joint and has little effect on the overall structure of the heat exchange plate 32. Moreover, the provision of the joint can achieve continuous flow of the heat exchange medium, thereby continuously dissipating heat.

[0101] According to an embodiment of the present application, the material of the heat exchange plate 32 is selected from aluminum or aluminum alloy.

[0102] In these optional embodiments, aluminum or aluminum alloy is a heat-conducting material with good thermal conductivity, which is conducive to rapid heat dissipation and cooling of the substrate 1.

[0103] Combined with reference Figure 4 and Figure 5 , Figure 4 is a structural schematic diagram of a battery production device provided in another embodiment of the present application; Figure 5 It is a schematic diagram of the structure of a heat exchange component of a battery production equipment provided in one embodiment of the present application.

[0104] According to one embodiment of the present application, Figure 4 and Figure 5 As shown, the battery production equipment 100 further includes an adsorbent 40 , which is configured to be located on a side of the heat exchange component 30 facing the substrate 1 .

The adsorbent 40 adsorbs the substrate 1, so that the heat exchange component 30 can be connected to the substrate 1 through the adsorbent 40 and cool the substrate 1. When the substrate 1 is transported to a predetermined position on the conveying mechanism 20 or the substrate 1 is disposed on the conveying mechanism 20, the heat exchange component 30 is attached to the substrate 1 through the adsorbent 40 to cool the substrate 1. After the substrate 1 is cooled to a preset temperature, the adsorption of the adsorbent 40 is released, and the heat exchange component 30 is separated from the substrate 1.

[0106] Optionally, the adsorbent 40 can be adsorbed on the substrate 1 by using a suction cup, tape or an electrostatic member.

[0107] The battery production equipment 100 includes one adsorption member 40 or multiple adsorption members 40. When the battery production equipment 100 includes multiple adsorption members 40, the multiple adsorption members 40 are arranged on the heat exchange component 30 at intervals along the transmission direction y, so that the substrate 1 and the heat exchange component 30 are in closer contact.

[0108] In these optional embodiments, the adsorbent 40 is provided to achieve stable contact between the heat exchange component 30 and the substrate 1, and reduce the gap between the heat exchange component 30 and the substrate 1, thereby improving the cooling effect. In addition, the provision of the adsorbent 40 has a certain buffering effect, which can improve the direct contact between the substrate 1 and the extremely cold heat exchange component 30, and provide a certain buffer for the cooling of the substrate 1.

[0109] According to an embodiment of the present application, the battery production equipment 100 further includes an air suction member 50 , which is connected to the adsorption member 40 .

[0112] In an embodiment of the present application, the adsorption member 40 is arranged on the side of the heat exchange component 30 facing the substrate 1, and the adsorption member 40 at least partially protrudes from the heat exchange component 30, so that the adsorption member 40 is first adsorbed on the lower surface of the substrate 1. The adsorption member 40 protruding from the heat exchange component 30 allows a smaller gap between the substrate 1 and the heat exchange component 30, thereby improving the sudden contact of the substrate 1 with the extremely cold heat exchange component 30 while achieving a cooling effect, so that the substrate 1 can be gradually and stably cooled.

[0113] Optionally, the adsorption member 40 is a suction cup.

[0114] According to one embodiment of the present application, Figure 4 and Figure 5 As shown, the heat exchange assembly 30 includes a heat exchange plate 32 , and a surface of the heat exchange plate 32 facing the substrate 1 is provided with an inwardly recessed recess 322 , and a portion of the adsorption member 40 is disposed in the recess 322 .

The first surface faces the substrate 1, and the first surface is provided with an inwardly recessed recess 322. A portion of the adsorbent 40 is arranged in the recess 322, and the other portion protrudes from the first surface.

[0117] According to an embodiment of the present application, the adsorption member 40 is made of polytetrafluoroethylene.

[0118] In these optional embodiments, the adsorbent 40 made of polytetrafluoroethylene can effectively reduce the damage to the adsorbent 40 caused by the substrate 1 at a higher temperature. At the same time, polytetrafluoroethylene has hydrophobic and oleophobic properties, which can effectively reduce oil pollution to the substrate 1.

[0119] According to one embodiment of the present application, Figure 4 and Figure 5 As shown, the battery production equipment 100 further includes a driving member 60 , which is connected to the heat exchange assembly 30 , and drives the heat exchange assembly 30 to rise and fall.

[0120] In an embodiment of the present application, the battery production equipment 100 also includes a driving member 60, which can be set on the bracket 10 and move up and down relative to the bracket 10. The driving member 60 is connected to the heat exchange component 30 to drive the heat exchange component 30 to rise and fall, thereby controlling the heat exchange component 30 to achieve the bonding and separation of the heat exchange component 30 and the substrate 1.

[0121] Specifically, after the conveying mechanism 20 receives the substrate 1 or the substrate 1 is conveyed to a predetermined position by the conveying mechanism 20, the driving member 60 drives the heat exchange assembly 30 to rise, so that the heat exchange assembly 30 is attached to the substrate 1 to exchange heat with the substrate 1. After the substrate 1 is cooled to a preset temperature, the driving member 60 drives the heat exchange assembly 30 to descend, and the conveying mechanism 20 conveys the substrate 1 to the next process.

[0122] The driving member 60 is a servo electrode, an air cylinder, a hydraulic cylinder, etc.

[0123] Optionally, the driving member 60 is a lifting cylinder.

[0124] In these optional embodiments, a driving member 60 is provided to realize the lifting and lowering of the heat exchange assembly 30 , and the heat exchange assembly 30 and the conveying mechanism 20 operate independently of each other, thereby reducing the interference of the heat exchange assembly 30 with the normal conveying of the substrate 1 on the conveying mechanism 20 .

[0125] According to one embodiment of the present application, Figure 2 As shown, the battery production equipment 100 further includes a temperature detection component 70 disposed on the bracket 10 , and the temperature detection component 70 is used to detect the temperature of the substrate 1 .

[0126] Optionally, the temperature detection member 70 includes a temperature sensor.

[0127] In these optional embodiments, by providing the temperature detection element 70 , the cooling effect of the heat exchange component 30 can be detected in real time, thereby reducing the problem of failure of cooling the substrate 1 due to abnormalities of the heat exchange component 30 .

[0128] A battery production device includes a bracket, a conveying mechanism, a heat exchange component, an adsorption component, an exhaust component, a driving component and a temperature detection component. The battery production device also includes a coating device, and the bracket is located downstream of the coating device.

[0129] The conveying mechanism is arranged on the bracket, and is used to receive and convey the substrate. The conveying mechanism includes two conveying belts arranged at intervals along a first direction, and the heat exchange component is arranged on both sides of the conveying mechanism along the first direction, and the heat exchange component is also arranged between two adjacent conveying belts. The first direction, the transmission direction of the substrate and the vertical direction of the bracket are perpendicular to each other.

[0130] The heat exchange component is movably arranged on the bracket and located on the transmission path of the substrate. The heat exchange component is used to exchange heat with the substrate. The heat exchange component includes a heat exchange plate, and a flow channel is provided in the heat exchange plate, and the flow channel is used to guide the flow of the heat exchange medium. The surface of the heat exchange plate facing the substrate is provided with an inwardly concave concave portion. The material of the heat exchange plate is selected from aluminum alloy.

[0131] The adsorbent is configured to be located on the side of the heat exchange component facing the substrate, a portion of the adsorbent is disposed in the recess, and another portion of the adsorbent protrudes from the heat exchange component. The adsorbent is connected to the heat exchange component and is used to adsorb the lower surface of the substrate. The adsorbent is made of polytetrafluoroethylene.

[0132] The suction component is communicated with the adsorption component.

[0133] The driving member is connected to the heat exchange component, and the driving member drives the heat exchange component to rise and fall.

[0134] The temperature detection component is arranged on the bracket, and is used for detecting the temperature of the substrate.

[0135] The temperature test and water drop angle test are performed on the substrate after being transported by the battery production equipment. The temperature test uses an infrared temperature tester to test the temperature of the upper and lower surfaces of the substrate at regular intervals. The water drop angle test uses a water drop angle tester to test the water drop angle of the substrate. The size of the water drop angle can reflect the wettability of the substrate.

[0136] Test results such as Figure 6 and Figure 7 As shown, Figure 6 The upper middle curve is the cooling curve of the upper surface of the substrate, and the lower middle curve is the cooling curve of the lower surface of the substrate. Figure 6It can be seen that the high-temperature substrate treated by the coating device is cooled by the heat exchange component. After the heat exchange component acts for 150 seconds, the upper and lower surface temperatures of the substrate reach room temperature, and the lower surface cools more significantly. Figure 7 The upper middle curve is the water drop angle curve of the substrate without heat exchange component treatment, and the lower curve is the water drop angle curve of the substrate after the heat exchange component treatment for 90 seconds. Figure 7 It can be seen that the water drop angle test was carried out on the substrate after 90s of heat exchange component treatment and the substrate without heat exchange component treatment. The values ​​of the water drop angle on the lower surface of the substrate were reduced, and with the increase of the static time, the overall change of the water drop angle value on the lower surface of the substrate was small, thereby improving the wettability.
