Description

Technical Field

[0001] The present application relates to the technical field of liquid flow batteries, and in particular to a method and device for preparing a liquid flow battery module. Background Art

[0002] Liquid flow battery is a device that converts chemical energy into electrical energy through electrochemical reactions and is widely used in the field of energy storage and conversion technology. Liquid flow battery modules include bipolar plates, electrode frames, proton membranes and hot melt adhesives. The hot melt adhesive bonding and sealing process is used to bond and seal the relevant structures of the liquid flow battery. Specifically, first apply a layer of hot melt adhesive on the surface of the bipolar plates, electrode frames and proton membranes, and then stack the materials with the hot melt adhesive layer in order and put them into a hot press. Heat and pressurize the hot melt adhesive at a certain temperature to melt it, so that the surfaces of the relevant structures are tightly bonded, thereby achieving the sealing of the liquid flow battery.

[0003] Although the existing flow battery module can achieve the sealing of the flow battery through the hot melt adhesive sealing process, when heating and melting the hot melt adhesive, a hot press is usually used to heat the flow battery module. This method is difficult to accurately control the melting temperature of the hot melt adhesive, and it is easy to cause the temperature of the hot melt adhesive on both sides of the flow battery module to be too high and the temperature in the middle to be too low, thereby affecting the bonding performance and sealing effect of the hot melt adhesive.

[0050] The present application provides a method for preparing a liquid flow battery module, and the method for preparing a liquid flow battery module comprises:

[0051] preparing a first layer material, a second layer material and a third layer material;

[0052] Bonding the first layer of material and the second layer of material by non-contact heating to form a first unit;

[0053] The third layer of material and the first unit are bonded by non-contact heating.

[0054] In the above method for preparing a liquid flow battery module, when preparing a liquid flow battery module, a first layer of material, a second layer of material and a third layer of material are first prepared, and then the first layer of material and the second layer of material are first bonded by hot pressing to form a first unit, and then the third layer of material and the first unit are bonded to complete the preparation of the liquid flow battery module. Compared with the existing unified heating by hot pressing process, the method for preparing a liquid flow battery module of the present application connects multiple layers of materials one by one, and the hot melt adhesive between two adjacent layers of materials is heated once, which not only facilitates the control of the heating temperature of the hot melt adhesive of each layer of material, but also solves the problem of the hot melt adhesive on both sides of the liquid flow battery module being too high and the middle temperature being too low, thereby improving the bonding performance and sealing effect of the liquid flow battery module. In addition, the use of this method to process the liquid flow battery module is not easy to cause deformation and cracking of the bipolar plates on both sides of the liquid flow battery module, thereby improving the overall performance of the liquid flow battery module.

[0055] It should be noted that the non-contact heating method refers to: heating the hot melt adhesive attached to the material by a heat source so that the hot melt adhesive melts and is easy to cold press to connect two adjacent layers of material. In the process of heating the hot melt adhesive, there is no contact between the heat source and the hot melt adhesive.

[0056] Specifically, bonding the first layer of material and the second layer of material by non-contact heating to form the first unit includes:

[0057] Get the first layer of materials;

[0058] Heat and melt the hot melt adhesive attached to the first layer of material;

[0059] Obtain a second layer of material and place it on the hot melt adhesive of the first layer of material, so that the hot melt adhesive attached to the second layer of material faces the side away from the first layer of material;

[0060] Press the second layer of material onto the first layer of material.

[0061] First, obtain the first layer of material, then heat and melt the hot melt adhesive attached to the first layer of material, then obtain the second layer of material and stack it on the hot melt adhesive of the first layer of material, and when placing the second layer of material, direct the hot melt adhesive attached to the second layer of material toward the side away from the first layer of material, and then press the second layer of material and the first layer of material together to form a first unit.

[0062] Specifically, bonding the third layer of material to the first unit by non-contact heating includes: heating and melting the hot melt adhesive attached to the second layer of material; obtaining the third layer of material and placing it on the hot melt adhesive of the second layer of material; pressing the third layer of material onto the second layer of material. The third layer of material is placed on the hot melt adhesive of the second layer of material, thereby achieving the connection between the third layer of material, the second layer of material, and the first layer of material. The present application bonds the multiple layers of material of the flow battery module one by one to prevent the bonding between two adjacent layers of material from being weak.

[0063] Furthermore, the above is just an example of a liquid flow battery module including a first layer of material, a second layer of material and a third layer of material. In some embodiments, the liquid flow battery module also includes more layers of material, and the multiple layers of material are connected and combined in a one-by-one bonding manner to form a liquid flow battery module.

[0064] Specifically, in this embodiment, multiple layers of first layer materials, multiple layers of second layer materials, and multiple layers of third layer materials are prepared; the multiple layers of first layer materials, multiple layers of second layer materials, and multiple layers of third layer materials are arranged in a circular manner in the order of first layer materials, second layer materials, and third layer materials, and any two adjacent layers of materials are bonded by non-contact heating. The prepared flow battery module includes multiple layers of first layer materials, multiple layers of second layer materials, and multiple layers of third layer materials. During preparation, the first layer materials and the second layer materials are first connected, and then the second layer materials and the third layer materials are connected, thereby connecting the first layer materials, the second layer materials, and the third layer materials, and then the next first layer materials are connected to the third layer materials, and then the next second layer materials are connected to the first layer materials, that is, they are connected step by step in the order of one, two, three, one, two, three...

[0065] It should be noted that arranging in a cycle in the order of the first layer of materials, the second layer of materials, and the third layer of materials means gradually connecting in the order of the first layer of materials, the second layer of materials, the third layer of materials, the first layer of materials, the second layer of materials, the third layer of materials….

[0066] It should be noted that the number of the first layer of material, the second layer of material and the third layer of material in the above embodiment is set according to the actual needs of the liquid flow battery module.

[0067] It should be noted that if the liquid flow battery module includes multiple third layer materials, in order to achieve the connection between the third layer material and the next first layer material, when preparing the third layer material, hot melt adhesive is laid on the third layer material, and when the third layer material is placed on the second layer material, the hot melt adhesive attached to the third layer material is directed to the side away from the second layer material, thereby facilitating bonding with the next first layer material.

[0068] Furthermore, the method for preparing a liquid flow battery module of the present application, after gradually connecting multiple first layer materials, multiple second layer materials and multiple third layer materials, lays a bipolar plate on the top third layer material, and bonds the top third layer material and the bipolar plate by non-contact heating.

[0069] Furthermore, heating and melting the hot melt adhesive attached to the first layer of material, the second layer of material, or the third layer of material includes: dividing the first layer of material, the second layer of material, or the third layer of material into an adhesive area and a non-adhesive area, heating the adhesive area, and cooling the non-adhesive area at the same time. When heating the hot melt adhesive attached to the first layer of material, the second layer of material, or the third layer of material, only the adhesive area of ​​the first layer of material, the second layer of material, or the third layer of material needs to be heated to achieve the connection of the two adjacent layers of material, while the non-adhesive area of ​​the first layer of material, the second layer of material, or the third layer of material does not need to be heated. In order to reduce the influence of the heat when heating the adhesive area on other components of the liquid flow battery module arranged in the non-adhesive area, the non-adhesive area is cooled while the adhesive area is heated.

[0070] It should be noted that the first layer of material, the second layer of material or the third layer of material is divided into a bonding area and a non-bonding area. The bonding area is arranged around the circumference of the non-bonding area. The bonding area is paved with hot melt adhesive, and the non-bonding area corresponds to the electrode of the liquid flow battery module.

[0071] In some embodiments, hot melt adhesive is only applied on the bonding area of ​​the material, and is not applied on the non-bonding area of ​​the material. Therefore, when heating and melting the hot melt adhesive attached to the material, only the bonding area of ​​the material needs to be heated, while the non-bonding area of ​​the material needs to be cooled to reduce the effect of the heat from the heated bonding area on the non-bonding area.

[0072] In some embodiments, hot melt adhesive is spread on the surface of the material. Therefore, when the hot melt adhesive attached to the material is heated and melted, it is only necessary to heat the hot melt adhesive corresponding to the bonding area of ​​the material, while cooling the hot melt adhesive in the non-bonding area of ​​the material.

[0073] Furthermore, pressing two adjacent layers of materials together includes: bringing the two adjacent layers of materials close to each other and attaching them together, and cooling the non-bonding area of ​​the two adjacent layers of materials. When pressing the two adjacent layers of materials together, the non-bonding area is cooled to further reduce the impact of heat on other components corresponding to the liquid flow battery module.

[0074] Furthermore, when preparing a liquid flow battery module, the first layer of material of the present application includes connected bipolar plates and hot melt adhesive; the hot melt adhesive bonding layer is evenly processed in the area that needs to be sealed on one side of the bipolar plate using any method such as spraying, brushing, and scraping, and the adhesive thickness is controlled at 0.1-1mm, thereby producing the first layer of material.

[0075] The third layer of material of the present application includes a connected electrode frame and hot melt adhesive; the hot melt adhesive layer is evenly processed by spraying, brushing, scraping or any other method in the area that needs to be sealed on one side of the electrode frame, and the adhesive thickness is controlled at 0.1-1mm, thereby producing the third layer of material.

[0076] The second layer of material of the present application includes an electrode frame, hot melt adhesive, a proton membrane and hot melt adhesive which are arranged and connected in sequence. When making the second layer of material, it can be further processed on the basis of the third layer of material. For example, a proton membrane with an outer dimension larger than the size of the reaction zone of the electrode frame is placed in the central area on one side of the hot melt adhesive layer of the third layer of material, and then the hot melt adhesive layer of the third layer of material is evenly processed above the proton membrane by spraying, brushing, scraping or any other method. The thickness of the adhesive layer is controlled to be 0.1-1mm, thereby forming a structure of electrode frame-hot melt adhesive-proton membrane-hot melt adhesive, thereby making the third layer of material.

[0077] Furthermore, when preparing the second layer of material and the third layer of material, carbon felt of preset size specifications is installed in the second layer of material and the third layer of material.

[0078] In summary, this application provides an overall workflow of a method for preparing a flow battery module:

[0079] Prepare multiple layers of first layer materials, multiple layers of second layer materials, and multiple layers of third layer materials;

[0080] Bonding the first layer of material and the second layer of material by non-contact heating to form a first unit;

[0081] Bonding the third layer of material to the first unit by non-contact heating to form a second unit;

[0082] Bonding the next first layer of material to the third layer of material of the second unit;

[0083] Bonding the next second layer of material to the first layer of material;

[0084] The process is repeated until the number of the first layer of material, the second layer of material, and the third layer of material bonded together meets the preset number;

[0085] The bipolar plate is bonded to the third layer of material on the top by non-contact heating.

[0086] The present application also provides a device for preparing a liquid flow battery module, which is applicable to the above-mentioned method for preparing a liquid flow battery module, such as Figure 1As shown, the device for preparing a liquid flow battery module includes: a heating mechanism 200, a moving mechanism 300 and a switching table 400; the moving mechanism 300 is used to sequentially grab a first layer of material, a second layer of material and a third layer of material and place them sequentially on the switching table 400, the switching table 400 has a first position and a second position, the second position is located in the heating area of ​​the heating mechanism 200, and the first position is located outside the heating area, and the switching table 400 can switch between the first position and the second position; when in the first position, the moving mechanism 300 grabs the corresponding material and places it on the switching table 400; when in the second position, the heating mechanism 200 heats the hot melt adhesive attached to the material carried by the switching table 400.

[0087] In the above-mentioned device for preparing a liquid flow battery module, the moving mechanism 300 follows the order of the first layer of material, the second layer of material, and the third layer of material. The moving mechanism 300 only grabs one material at a time and places it on the switching table 400, that is, the moving mechanism 300 first grabs the first layer of material and places it on the switching table 400 at the first position, and the switching table 400 drives the first layer of material to switch to the second position, that is, the switching table 400 drives the first layer of material to move to the heating area of ​​the heating mechanism 200 to heat the hot melt adhesive attached to the first layer of material. When the hot melt adhesive attached to the first layer of material is heated to a preset temperature, the switching table 400 switches to the first position, that is, the switching table 400 drives the first layer of material to move out of the heating area. hot area; then, the moving mechanism 300 grabs the second layer of material, and stacks the second layer of material on the hot melt adhesive of the first layer of material, so that the hot melt adhesive of the first layer of material connects the first layer of material and the second layer of material; then, the switching table 400 drives the connected first layer of material and the second layer of material to switch to the second position, thereby heating the hot melt adhesive attached to the second layer of material. When the hot melt adhesive of the second layer of material is heated to a preset temperature, the switching table 400 drives the first layer of material and the second layer of material to switch to the first position; finally, the moving mechanism 300 grabs the third layer of material, and stacks the third layer of material on the hot melt adhesive of the second layer of material, so that the hot melt adhesive of the second layer of material connects the second layer of material and the third layer of material.

[0088] Compared with the existing uniform heating by hot pressing process, the device for preparing liquid flow battery module of the present application, the heating mechanism 200, the motion mechanism 300 and the switching table 400 cooperate with each other to achieve the bonding of multiple layers of materials one by one, and the hot melt adhesive between each layer of material is heated once, which not only facilitates the control of the heating temperature of the hot melt adhesive of each layer of material, but also solves the problem of the hot melt adhesive temperature on both sides of the liquid flow battery module being too high and the middle temperature being too low, thereby improving the bonding performance and sealing effect of the liquid flow battery module. In addition, the use of this device to process the liquid flow battery module is not easy to cause deformation and cracking of the bipolar plates on both sides of the liquid flow battery module, thereby improving the overall performance of the liquid flow battery module.

[0089] Furthermore, if Figure 1 As shown, a device for preparing a flow battery module also includes a mounting platform 100 and a material rack 500; the material rack 500, the motion mechanism 300, the switching table 400 and the heating mechanism 200 are all arranged on the mounting platform 100, the material rack 500 and the switching table 400 are arranged at intervals along the first direction, the switching table 400 and the heating mechanism 200 are arranged at intervals along the second direction, and the switching table 400 can move along the second direction to switch between the first position and the second position, the motion mechanism 300, the switching table 400 and the mounting platform 100 are arranged along the third direction, and the motion mechanism 300 can move along the first direction, wherein the third direction is the height direction of the mounting platform 100, and any two of the first direction, the second direction and the third direction are perpendicular. By arranging the material rack 500 and the switching table 400 along the first direction, the motion mechanism 300 can move along the first direction, so that the material on the material rack 500 is placed on the switching table 400. The switch table 400 and the heating mechanism 200 are arranged along the second direction, and the switch table 400 is moved along the second direction to switch between the first position and the second position. The motion mechanism 300, the switch table 400 and the mounting platform 100 are arranged along the third direction, and the motion mechanism 300 can move along the third direction to obtain materials on the material rack 500, or place the obtained materials on the switch table 400.

[0090] It should be noted that in this embodiment, the first direction is the length direction of the installation platform 100, and the second direction is the width direction of the installation platform 100. In other embodiments, the first direction is the width direction of the installation platform 100, and the second direction is the length direction of the installation platform 100.

[0091] It should be noted that the material rack 500 is used to carry multiple layers of materials. When preparing the liquid flow battery module, the order in which the motion mechanism 300 grabs the materials is: first layer of material, second layer of material, third layer of material, first layer of material, second layer of material... Therefore, the multiple layers of materials are arranged on the material rack 500 from bottom to top in the order of: third material, second material, first material, third material, second material, first material...

[0092] A layer of bipolar plates is also arranged at the bottom layer of the material rack 500 , and the bipolar plates are finally obtained by the motion mechanism 300 and pasted on the third layer of materials at the top layer of the switching table 400 .

[0095] More specifically, a plurality of first position-limiting members are disposed on the installation platform 100 , and the plurality of first position-limiting members are arranged around the circumference of the material rack 500 .

[0096] In this embodiment, three first limiting members are provided, and the three limiting members and the side edges of the installation platform 100 are arranged to form a limiting space, and the material rack 500 can be pushed into the limiting space from the end of the installation platform 100 .
