Description

Technical Field

[0001] The present invention relates to the technical field of battery manufacturing, and in particular to an integrated device for semi-solid battery electrolyte injection and packaging. Background Art

[0002] Combining the high energy density of rechargeable batteries with the flexible, scalable architecture of fuel cells and flow batteries to form a semi-solid flow battery, that is, adding solid active materials to liquid electrolytes to make a flowable mud-like slurry electrolyte, greatly improving the energy density and cycle life of the battery.

[0003] like Figure 1 As shown in the figure, the semi-solid liquid flow battery is mainly composed of a battery reactor, a positive electrode storage tank and a negative electrode storage tank. A circulating pump is used to circulate the slurry electrolyte between the battery reactor and the storage tank. Inside the battery reactor, the positive electrode slurry electrolyte and the negative electrode slurry electrolyte are separated by a diaphragm. When charging, the ions inside the battery move from the positive electrode to the negative electrode, and the electrons move from the positive electrode to the negative electrode through the external circuit; when discharging, the movement direction of ions and electrons is opposite to that during charging.

[0004] In the prior art, when semi-solid flow batteries are used as fuel cells for electric vehicles, the battery reactors are mostly designed to be thin sheets. The thin sheet structure causes the positive and negative electrode reaction cells inside to be narrow and long three-dimensional spaces. When the electrolyte is injected into the battery reactor, since the electrolyte is in a viscous slurry state, the electrolyte is very easy to adhere to the inner wall of the reaction cell during the injection process into the battery reactor. The electrolyte hanging on the inner wall of the reaction cell flows downward relatively slowly, and the injection port of the reaction cell may be blocked in a short time, which will not only increase the time required for subsequent electrolyte injection, but also cause the air inside the reaction cell to be unable to be discharged, thereby forming a large number of voids and bubbles inside the electrolyte. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcoming in the prior art that it takes a long time to inject slurry electrolyte into a battery reactor, and to propose an integrated device for injecting and packaging semi-solid battery electrolyte.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] Preferably, a protective structure is provided on the baffle to protect the diaphragm of the battery reactor, the protective structure includes a bidirectional stud and a connecting plate, the bidirectional stud is rotatably mounted on the sealing plug and the baffle, a small motor is mounted on the mounting plate to drive the bidirectional stud to rotate, both ends of the bidirectional stud are threadedly fitted with an articulated seat, a first connecting rod is hinged on the articulated seat, an internally threaded tube is threaded on the first connecting rod, a second connecting rod is internally threaded on the internally threaded tube, the connecting plate is slidably fitted between the sealing plug and the baffle, a bearing seat is fixedly connected to the connecting plate, a rotating shaft is rotatably mounted on the bearing seat, and the second connecting rod is fixedly connected to the rotating shaft.

[0010] Preferably, hinges are installed on both sides of the connecting plate, and the connecting plate is seamlessly hinged with a first sealing plate through the hinges. The first sealing plate is slidably equipped with a second sealing plate, and the second sealing plate is slidably equipped with a nut seat. A spring is fixed to the second sealing plate to apply elastic force to the nut seat. Screws are connected to both ends of the rotating shaft through universal joints, and the screw threads are engaged in the nut seat.

[0011] Preferably, a shell is fixedly connected to the mounting plate, and the shell is divided into a pressure regulating chamber and a slurry chamber, and the pressure regulating chamber is connected to the slurry chamber, wherein:

[0017] The present invention proposes an integrated device for injecting and packaging a semi-solid-state battery electrolyte, which has the beneficial effect that before injecting slurry electrolyte into the battery reactor, the integrated device maintains a negative pressure inside the battery reactor through an exhaust pipe, and under the action of the pressure difference, the injection pipe starts injecting from the bottom of the battery reactor, which not only enables the slurry electrolyte to be quickly injected into the battery reactor, but also effectively reduces problems such as wall adhesion and bubbles of the slurry electrolyte.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Example 1: Reference Figure 2 and Figure 3, a semi-solid battery electrolyte injection and packaging integrated device, comprising a feeding track 2 for transporting a battery reactor 5, the battery reactor 5 slidingly cooperates with the feeding track 2, and a frame 1 is fixedly connected at both ends of the feeding track 2 to drive the battery reactor 5 to slide on the feeding track 2;

[0036] When injecting slurry electrolyte into the battery reactor 5 , the device places the battery reactor 5 on the loading track 2 , and drives the battery reactor 5 to slide on the loading track 2 through the frame 1 to adjust the position of the battery reactor 5 .

[0037] like Figure 3-Figure 8 As shown, a first cylinder 201 is fixedly connected to the loading track 2, a mounting plate 6 is fixedly connected to the output end of the first cylinder 201, a sealing plug 15 made of rubber is fixedly connected to the mounting plate 6 to seal the injection port of the battery reactor 5, an exhaust pipe 10 and an injection pipe 11 are fixedly connected to the sealing plug 15, the bottom of the exhaust pipe 10 and the injection pipe 11 are fixedly connected to the baffle 30, an air intake port 14 is provided at the top of the exhaust pipe 10 to suck the air in the battery reactor 5, and a discharge port 31 is provided at the bottom of the injection pipe 11 to inject the slurry electrolyte into the bottom of the battery reactor 5.

[0038] During the slurry electrolyte injection process, the frame 1 drives the battery reactor 5 to move along the loading track 2 to the loading station. During this process, the first cylinder 201 controls the mounting plate 6 to be located at the highest point to make way for the loading station, so that the battery reactor 5 can smoothly enter the loading station.

[0039] The battery reactor 5 stops moving after it moves to the loading station. At this time, the first cylinder 201 drives the mounting plate 6 to move from top to bottom until the sealing plug 15 seals the injection port of the battery reactor 5 .

[0040] After the sealing plug 15 seals the injection port, both the exhaust pipe 10 and the injection pipe 11 will be located inside the battery reactor 5. At this time, the battery reactor 5 is evacuated through the exhaust pipe 10 to keep the inside of the battery reactor 5 in a negative pressure state, and then, slurry electrolyte in a slurry state is injected into the battery reactor 5 through the injection pipe 11.

[0041] Since the discharge port 31 is located at the bottom of the injection tube 11, the slurry electrolyte will accumulate upward from the bottom of the battery reactor 5, thereby preventing the appearance of voids and bubbles at the bottom of the battery reactor 5, and under the action of negative pressure, the slurry electrolyte will enter the battery reactor 5 faster, thereby improving the efficiency of electrolyte injection.

[0042] Since the air inlet 14 of the exhaust pipe 10 is located at the top, the slurry electrolyte injected into the bottom of the battery reactor 5 will not affect the air inlet 14 when the injection work is just started.

[0043] With the continuous injection of slurry electrolyte, the liquid level of slurry electrolyte inside the battery reactor 5 will gradually increase. When the liquid level of slurry electrolyte injected into the battery reactor 5 is about to reach the position of the air intake port 14, the battery reactor 5 below the air intake port 14 is already full of electrolyte. At this time, the first cylinder 201 drives the mounting plate 6 to move upward, so that the exhaust pipe 10 and the injection pipe 11 are pulled upward from the battery reactor 5. As the exhaust pipe 10 is pulled out of the battery reactor 5, the height of the air intake port 14 will also rise accordingly.

[0044] When the height of the air intake port 14 is higher than the height of the injection port of the battery reactor 5 and the discharge port 31 at the bottom of the injection tube 11 is located below the slurry liquid level inside the battery reactor 5, the injection tube 11 will inject slurry electrolyte into the battery reactor 5 from below the liquid level until the battery reactor 5 is filled with the slurry. During this process, the slurry electrolyte flowing out of the discharge port 31 cannot come into contact with the air, thereby preventing air from entering the battery reactor 5.

[0045] like Figure 2 and Figure 3 As shown, the feeding track 2 is fixedly connected with a second cylinder 202 and a third cylinder 203, wherein: the output end of the second cylinder 202 is fixedly connected with a first vacuum suction cup fixture 4 to grab the bottom end cover 401 of the battery reactor 5; the output end of the third cylinder 203 is fixedly connected with a second vacuum suction cup fixture 3 to grab the top end cover 301 of the battery reactor 5.

[0046] When the frame 1 drives the battery reactor 5 to move to the loading station, the second cylinder 202 will drive the first vacuum suction cup clamp 4 to move, and the bottom end cover 401 will be sealed and connected to the bottom opening of the battery reactor 5 through the first vacuum suction cup clamp 4 to encapsulate the bottom of the battery reactor 5.

[0047] After the battery reactor 5 is injected with slurry electrolyte, the rack 1 drives the battery reactor 5 to move to the third cylinder 203 . The third cylinder 203 uses the second vacuum suction cup fixture 3 to allow the top end cover 301 to seal the injection port at the top of the battery reactor 5 .

[0048] Embodiment 2: Figure 4-Figure 10As shown, a protective structure is provided on the baffle 30 to protect the diaphragm of the battery reactor 5, and the protective structure includes a bidirectional stud 13 and a connecting plate 20. The bidirectional stud 13 is rotatably mounted on the sealing plug 15 and the baffle 30. A small motor 12 is installed on the mounting plate 6 to drive the bidirectional stud 13 to rotate. Both ends of the bidirectional stud 13 are threadedly fitted with an articulated seat 16, and a first connecting rod 17 is hinged on the articulated seat 16. The first connecting rod 17 is threadedly fitted with an internal threaded tube 18, and the internal threaded tube 18 is internally threaded with a second connecting rod 19. The connecting plate 20 is slidably fitted between the sealing plug 15 and the baffle 30. A bearing seat 28 is fixedly connected to the connecting plate 20, and a rotating shaft 29 is rotatably mounted on the bearing seat 28, and the second connecting rod 19 is fixedly connected to the rotating shaft 29.

[0049] like Fig. 9 As shown, the small motor 12 will drive the bidirectional stud 13 to rotate after being energized, and the rotation of the bidirectional stud 13 will drive the two articulated seats 16 to move closer to or away from each other along the bidirectional stud 13. When the two articulated seats 16 move along the bidirectional stud 13, the articulated seats 16 will drive the connecting plate 20 to move horizontally in the battery reactor 5 through the cooperation of the first connecting rod 17, the internal threaded tube 18 and the second connecting rod 19.

[0050] Hinges 21 are installed on both sides of the connecting plate 20, and the connecting plate 20 is seamlessly hinged with a first sealing plate 22 through the hinges 21. A second sealing plate 23 is slidably matched on the first sealing plate 22, and a nut seat 24 is slidably matched on the second sealing plate 23. A spring 25 is fixed to the second sealing plate 23 to apply elastic force to the nut seat 24. Screws 26 are connected to both ends of the rotating shaft 29 through universal joints 27, and the screws 26 are threadedly matched in the nut seat 24.

[0051] During the horizontal movement of the connecting plate 20, the second connecting rod 19 will drive the rotating shaft 29 to rotate, and the rotation of the rotating shaft 29 will drive the screw 26 to rotate through the universal joint 27. The rotation of the screw 26 will drive the nut seat 24 to move. The movement of the nut seat 24 will apply force to the second sealing plate 23 through the spring 25. After the second sealing plate 23 is subjected to the force, it will slide on the first sealing plate 22, so that the second sealing plate 23 can be against the inner wall of the battery reactor 5.

[0052] like Figure 11-Figure 14As shown, taking the negative electrode reaction tank of the battery reactor 5 as an example, when working, the small motor 12 drives the bidirectional stud 13 to rotate, so that the two hinged seats 16 are close to each other. The closeness of the two hinged seats 16 will make the connecting plate 20 in the negative electrode reaction chamber close to the diaphragm on the left side. In this process, the second connecting rod 19 will drive the rotating shaft 29 to rotate, so that the second sealing plate 23 on the first sealing plate 22 is close to the inner wall of the negative electrode reaction tank until the second sealing plate 23 is against the inner wall of the negative electrode reaction tank. At this time, the connecting plate 20, the first sealing plate 22 and the second sealing plate 23 form a partition inside the negative electrode reaction tank, separating the diaphragm from the exhaust pipe 10. When the exhaust pipe 10 sucks the negative electrode reaction tank, the negative pressure generated will not affect the diaphragm, thereby preventing the diaphragm from being damaged by the action of air pressure.

[0053] Embodiment 3: Figure 4-6 As shown, a shell 7 is fixedly connected to the mounting plate 6, and the shell 7 is divided into a pressure regulating chamber 701 and a slurry chamber 702. The pressure regulating chamber 701 is connected to the slurry chamber 702, wherein: an injection pipe 11 is connected to the slurry chamber 702, and a feed pipe 703 is provided on the slurry chamber 702; a piston 8 is slidably fitted in the pressure regulating chamber 701, an electric cylinder 9 is fixedly connected to the pressure regulating chamber 701, and an output end of the electric cylinder 9 is connected to the piston 8, and an exhaust pipe 10 is connected to the pressure regulating chamber 701.

[0054] The slurry chamber 702 is used to store the slurry electrolyte, and the feed pipe 703 is used to add the slurry electrolyte to the slurry chamber 702. When the electrolyte injection work is performed:

[0055] like Figure 6 As shown, the electric cylinder 9 drives the piston 8 to move downward in the pressure regulating chamber 701, the air pressure above the piston 8 decreases, and the air pressure below the piston 8 increases;

[0056] The piston 8 is connected to the exhaust pipe 10. When the air pressure above the piston 8 decreases, the air in the battery reactor 5 is sucked through the exhaust pipe 10.

[0057] The piston 8 is connected to the slurry chamber 702 below. When the air pressure below the piston 8 increases, the pressure in the slurry chamber 702 connected thereto will also increase, so that the slurry electrolyte in the slurry chamber 702 can be injected into the battery reactor 5 faster through the injection pipe 11 under the action of pressure.

[0058] Working principle and workflow:

[0059] S1: When injecting slurry electrolyte into the battery reactor 5, the battery reactor 5 is placed on the loading track 2, and the frame 1 drives the battery reactor 5 to move along the loading track 2 to the loading station. During this process, the first cylinder 201 controls the mounting plate 6 to be located at the highest point to make way for the loading station, so that the battery reactor 5 can smoothly enter the loading station.

[0060] S2: The second cylinder 202 drives the first vacuum suction cup fixture 4 to move, and the bottom end cover 401 is sealed and connected to the bottom opening of the battery reactor 5 through the first vacuum suction cup fixture 4 to encapsulate the bottom of the battery reactor 5 .

[0061] S3: The first cylinder 201 drives the mounting plate 6 to move from top to bottom until the sealing plug 15 seals the injection port of the battery reactor 5 . At this time, both the exhaust pipe 10 and the injection pipe 11 are inserted into the battery reactor 5 .

[0062] S4: Start the small motor 12, the small motor 12 drives the bidirectional stud 13 to rotate, the rotation of the bidirectional stud 13 drives the two articulated seats 16 to move closer to or away from each other along the bidirectional stud 13, when the two articulated seats 16 move along the bidirectional stud 13, the articulated seats 16 drive the connecting plate 20 to move horizontally in the battery reactor 5 through the cooperation of the first connecting rod 17, the internal threaded tube 18 and the second connecting rod 19;

[0063] During the horizontal movement of the connecting plate 20, the second connecting rod 19 will drive the rotating shaft 29 to rotate, and the rotation of the rotating shaft 29 will drive the screw 26 to rotate through the universal joint 27. The rotation of the screw 26 will drive the nut seat 24 to move. The movement of the nut seat 24 will apply force to the second sealing plate 23 through the spring 25. After the second sealing plate 23 is subjected to the force, it will slide on the first sealing plate 22, so that the second sealing plate 23 can be against the inner wall of the battery reactor 5.

[0064] S5: The electric cylinder 9 drives the piston 8 to move downward in the pressure regulating chamber 701, the air pressure above the piston 8 decreases, and the air pressure below the piston 8 increases, wherein:

[0065] The piston 8 is connected to the exhaust pipe 10. When the air pressure above the piston 8 decreases, the air in the battery reactor 5 is sucked through the exhaust pipe 10.

[0066] The piston 8 is connected to the slurry chamber 702 below. When the air pressure below the piston 8 increases, the pressure in the slurry chamber 702 connected thereto will also increase, so that the slurry electrolyte in the slurry chamber 702 can be injected into the battery reactor 5 faster through the injection pipe 11 under the action of pressure.

[0067] S6: With the continuous injection of slurry electrolyte, the liquid level of slurry electrolyte inside the battery reactor 5 will gradually increase. When the liquid level of slurry electrolyte injected into the battery reactor 5 is about to reach the position of the air intake port 14, the battery reactor 5 below the air intake port 14 is already full of electrolyte. At this time, the small motor 12 drives the bidirectional stud 13 to reverse and reset.

[0068] During the resetting process, the first sealing plate 22 will bend on the connecting plate 20 with the hinge 21 as the axis, and the second sealing plate 23 will also rotate with the universal joint 27 as the center to reduce the resistance encountered by the first sealing plate 22 and the second sealing plate 23 during the resetting process.

[0069] S7: After the two hinged seats 16 on the two-way stud 13 are reset, the first cylinder 201 drives the mounting plate 6 to move upward, so that the exhaust pipe 10 and the injection pipe 11 are pulled upward from the battery reactor 5. As the exhaust pipe 10 is pulled out of the battery reactor 5, the height of the air inlet 14 will also rise accordingly.

[0070] S8: When the height of the air intake port 14 is higher than the height of the injection port of the battery reactor 5 and the discharge port 31 at the bottom of the injection tube 11 is located below the slurry liquid level inside the battery reactor 5, the injection tube 11 will inject slurry electrolyte into the battery reactor 5 from below the liquid level until the battery reactor 5 is filled with the slurry. During this process, the slurry electrolyte flowing out of the discharge port 31 cannot come into contact with the air, thereby preventing air from entering the battery reactor 5.

[0071] S9: After the battery reactor 5 is injected with slurry electrolyte, the frame 1 drives the battery reactor 5 to move to the third cylinder 203. The third cylinder 203 uses the second vacuum suction cup fixture 3 to allow the top end cover 301 to seal the injection port at the top of the battery reactor 5. At this time, the electrolyte injection and packaging work of the battery reactor 5 is completed.

[0072] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
