Description

Technical Field

[0001] The present invention relates to the technical field of aluminum-air batteries, in particular to aluminum-air batteries. Background Art

[0002] An aluminum-air battery generates electricity through a chemical reaction between aluminum and oxygen in the air. High-purity aluminum serves as the negative electrode, oxygen in the air serves as the positive electrode, and potassium hydroxide or sodium hydroxide aqueous solution is typically used as the electrolyte. During discharge, the aluminum absorbs oxygen from the air and reacts with hydroxide ions in the electrolyte to produce aluminum oxide and water, releasing electricity.

[0003] An aluminum-air battery module disclosed in Chinese patent publication number CN112542637A has an additional air pressurization system in the aluminum-air battery module. When the battery module is working, high-pressure air or pure oxygen is input into the closed air pressurization system through a blower. The high-pressure air or pure oxygen enters the intake air hood and the exhaust air hood through the air pipe, and then enters between the two air electrodes through the air circulation ports on both sides of the double electrode and the single electrode. The oxygen contained in the high-pressure air or pure oxygen can increase the reaction rate of the air electrode reduction reaction, thereby improving the discharge performance of the battery under high-power discharge.

[0004] However, compared to existing technologies in related fields, at the negative electrode (aluminum electrode) of aluminum-air batteries, aluminum reacts with water in the electrolyte to generate hydrogen and hydroxide ions. Hydrogen escapes from the electrolyte in the form of bubbles. At the same time, during battery operation, the temperature of the electrolyte may rise, causing some electrolyte to evaporate and form bubbles. The generation of bubbles may affect battery performance because they may block the flow of electrolyte and affect ion transport, thereby increasing the battery's internal resistance and reducing battery efficiency. In addition, bubbles may adhere to the electrode due to the viscosity of the electrolyte or the properties of the electrode surface, making it difficult to escape. The bubbles covering the electrode surface reduce the actual contact area between the electrode and the electrolyte, thereby reducing the electrode's efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0032] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components.

[0034] like Figures 1 to 12 As shown, the aluminum-air battery includes a mounting box 1, wherein a plurality of aluminum-air battery assemblies 2 are fixedly mounted inside the mounting box 1, a heat dissipation assembly 3 for dissipating heat to the aluminum-air battery assemblies 2 and an infusion assembly 4 for providing electrolyte to the aluminum-air battery assemblies 2 are provided at the bottom of the mounting box 1, and a gas supply assembly 5 for providing air to the aluminum-air battery assemblies 2 is fixedly mounted on the outside of the mounting box 1; the aluminum-air battery assembly 2 includes a shell 201 fixedly mounted inside the mounting box 1, positive plates 202 are fixedly provided on both sides of the shell 201, a frame 203 is plugged into the interior of the shell 201, a plurality of insulating frames 205 are rotatably provided inside the frame 203, and aluminum plates 204 are embedded and mounted inside the plurality of insulating frames 205, and a driving assembly 6 for controlling the synchronous rotation of the plurality of insulating frames 205 according to temperature is fixedly provided at the bottom of the frame 203. When the temperature of the aluminum-air battery assembly 2 is high, the driving assembly 6 is used to control the rotation of the insulating frame 205, thereby causing the plurality of insulating frames 205 to collide with the positive plate 202 When the temperature of the aluminum-air battery assembly 2 returns to normal, the driving assembly 6 is used to control the multiple insulating frames 205 to rotate back. The materials of the insulating frames 205 and the frame 203 are both polytetrafluoroethylene, which can prevent the aluminum plate 204 from contacting the positive plate 202, and at the same time make the insulating frame 205 and the frame 203 have a corrosion-resistant effect; a control module 7 is fixedly installed at one end of the installation box 1, and the top of the positive plate 202 is fixed with a positive lead-out ear 206, and the top of the frame 203 is fixed with a There is a negative electrode lead-out tab 207, and the positive electrode lead-out tab 206 and the negative electrode lead-out tab 207 are electrically connected to the control module 7 respectively. A breathable cover 2011 is fixedly installed on the top of the shell 201, and the breathable cover 2011 is provided with sealing holes at the positions corresponding to the positive electrode lead-out tab 206 and the negative electrode lead-out tab 207. The breathable cover 2011 can be used to quickly discharge unnecessary gases generated during the reaction of the aluminum plate 204 to avoid unnecessary gases remaining inside the shell 201.

[0035] like Figures 5 to 12As shown, the drive assembly 6 includes a mounting groove 601 provided inside the frame 203, a rack 602 is slidingly provided inside the mounting groove 601, a plurality of insulating frames 205 are fixedly provided with gear shafts 603 at positions corresponding to the rack 602, and a plurality of gear shafts 603 are engaged with the rack 602, and the mounting groove 601 is located at one end of the rack 602 and fixedly provided with a temperature-sensitive elastic member 604, the temperature-sensitive elastic member 604 is connected to the rack 602 through a connecting member 605, the material of the temperature-sensitive elastic member 604 is memory metal, and the memory metal has a two-way shape memory effect (two-way shape memory effect: the high-temperature phase shape is restored when heated, and the low-temperature phase shape is restored when cooled, that is, the phenomenon of spontaneously and reversibly restoring the high and low temperature phase shapes by temperature rise and fall, or called reversible shape memory effect), the shape of the connecting member 605 is L-shaped, an air hole 2031 is provided at the bottom of the frame 203 corresponding to the connecting member 605, and an air pipe 2031 is fixedly provided at the position of the shell 201 corresponding to the air hole 2031 32. When the temperature of the aluminum-air battery assembly 2 is high, the temperature-sensitive elastic member 604 will push the connector 605, so that the connector 605 no longer blocks the air hole 2031, and the air pipe 2032 is connected to the mounting groove 601 through the air hole 2031. When the temperature of the aluminum-air battery assembly 2 returns to normal, the temperature-sensitive elastic member 604 will pull back the connector 605, so that the connector 605 blocks the air hole 2031 and cuts off the connection between the air pipe 2032 and the mounting groove 601. The tops of the multiple insulating frames 205 are rotatably connected to the frame 203 through the rotating shaft 2051. The frame 203 is provided with rotating holes at positions corresponding to the rotating shaft 2051 and the gear shaft 603. The rotating shaft 2051 and the gear shaft 603 are both connected to the rotating holes through bearings. The bearings are sealed bearings, thereby preventing the electrolyte from entering the interior of the mounting groove 601. The above-mentioned bearings can reduce the friction during the rotation of the insulating frame 205 and improve the stability of the insulating frame 205 during rotation.

[0036] like Figure 7 and Figure 8 As shown, electrical connecting wires are provided at the center of the rotating shaft 2051 and inside the insulating frame 205, and the electrical connecting wires are used to electrically connect the aluminum plate 204 with the negative electrode lead-out tab 207. At the same time, the aluminum plate 204 is embedded and installed inside the insulating frame 205, so that the aluminum plate 204 can be easily replaced.

[0037] like Figures 5 to 12 As shown, in summary, when the temperature of the aluminum-air battery assembly 2 is high, the driving assembly 6 is used to control the rotation of the insulating frame 205, thereby causing the insulating frame 205 to collide with the positive plate 202 (such as Figures 9 to 12As shown, when the temperature of the aluminum-air battery assembly 2 is high, the temperature-sensitive elastic member 604 will push the connecting member 605, thereby allowing the rack 602 to slide. At this time, the rack 602 is used to prompt the gear shaft 603 to drive the insulating frame 205 to rotate). The collision can make the aluminum plate 204 and the positive plate 202 vibrate, thereby shaking off the bubbles attached to the surface of the aluminum plate 204 and the positive plate 202, ensuring the actual contact area between the aluminum plate 204 and the electrolyte, ensuring the efficiency of the electrode, and the insulating frame 205 and the aluminum plate 204 are rotating. It will stir the electrolyte and promote the flow of the electrolyte, thereby breaking up the bubbles. When the temperature of the aluminum-air battery assembly 2 returns to normal, the temperature-sensitive elastic member 604 will pull back the connector 605, so that the connector 605 blocks the air hole 2031 and cuts off the connection between the air pipe 2032 and the mounting groove 601. At the same time, through the rack 602, the gear shaft 603 drives the insulating frame 205 and the aluminum plate 204 to rotate in the opposite direction, so that the multiple insulating frames 205 rotate back to a flush state and allow the aluminum plate 204 to continue to maintain chemical reaction.

[0038] like Figures 1 to 3 As shown, the heat dissipation component 3 includes a mounting plate 301 fixedly mounted on the bottom of the mounting box 1, and a plurality of heat dissipation fans 302 are fixedly mounted inside the mounting plate 301. A temperature sensor is provided inside the mounting plate 301. When the temperature of the aluminum-air battery assembly 2 is high, the temperature detected by the temperature sensor provided inside the mounting plate 301 rises, and the heat dissipation fan 302 of the heat dissipation component 3 will quickly increase the power, and then the aluminum-air battery assembly 2 can be cooled. At the same time, when the temperature-sensitive elastic member 604 pushes the connecting member 605, the connecting member 605 no longer blocks the air hole 2031, so that the air pipe 2032 is connected to the mounting groove 601 through the air hole 2031, thereby being able to dissipate heat for the components inside the mounting groove 601 (such as Figures 9 to 12 shown).

[0039] like Figures 1 to 4 As shown, the infusion component 4 includes an infusion main line 401 fixedly mounted on the mounting plate 301, and the positions of the infusion main line 401 corresponding to the multiple shells 201 are fixedly provided with a first infusion branch pipe 402 and a second infusion branch pipe 403, and the positions of the shell 201 corresponding to the first infusion branch pipe 402 and the second infusion branch pipe 403 are respectively provided with a first connecting hole 2012 and a second connecting hole 2013. When the electrolyte needs to be replaced, the electrolyte inside the shell 201 can be discharged into the infusion main line 401 through the first connecting hole 2012 and the infusion branch pipe 402, and then discharged through the infusion main line 401. After the discharge is completed, the new electrolyte can be injected into the shell 201 from the second infusion branch pipe 403 and the second connecting hole 2013 through the infusion main line 401.

[0040] like Figures 1 to 3As shown, the gas delivery assembly 5 includes a gas delivery main line 501 fixedly installed on the outer surface of the installation box 1, and the gas delivery main line 501 corresponds to the outer sides of multiple positive plates 202, each of which is fixedly provided with a gas delivery branch pipe 502. Using the above scheme, high-pressure air or pure oxygen can be injected into the installation box 1 to increase the reaction rate of the air electrode reduction reaction, thereby improving the discharge performance of the battery under high-power discharge.

[0041] The heat dissipation component 3, temperature sensor, infusion component 4, gas transmission component 5, positive electrode plate 202, aluminum plate 204, positive electrode lead-out tab 206, negative electrode lead-out tab 207, electrical connecting wire, control module 7 and sealed bearing described in this application are all well-known technologies in the technical field, so their specific structure and working principle are not described in detail.

[0042] The working process is as follows:

[0043] S1, such as Figures 1 to 8 As shown, during operation, the aluminum plate 204 absorbs oxygen from the electrolyte to produce water and hydrogen products, while releasing electrical energy, which is then transferred to the control module 7 through the lead tabs to supply power to the electrical equipment;

[0044] S2, such as Figures 1 to 8 As shown, when aluminum reacts with water in the electrolyte to generate hydrogen and hydroxide ions, hydrogen escapes from the electrolyte in the form of bubbles. At the same time, during the operation of the battery, the temperature of the electrolyte may increase, causing part of the electrolyte to evaporate and form bubbles, which then adhere to the surfaces of the aluminum plate 204 and the positive plate 202;

[0045] S3, such as Figures 5 to 12 As shown, when the temperature of the aluminum-air battery assembly 2 is high, the driving assembly 6 is used to control the rotation of the insulating frame 205, thereby causing the insulating frame 205 to collide with the positive plate 202 (when the temperature of the aluminum-air battery assembly 2 is high, the temperature-sensitive elastic member 604 will push the connecting member 605, thereby causing the rack 602 to slide. At this time, the rack 602 is used to cause the gear shaft 603 to drive the insulating frame 205 to rotate). The collision can cause the aluminum plate 204 and the positive plate 202 to vibrate, thereby shaking off the bubbles attached to the surfaces of the aluminum plate 204 and the positive plate 202, ensuring the actual contact area between the aluminum plate 204 and the electrolyte, and ensuring the efficiency of the electrode. In addition, the insulating frame 205 and the aluminum plate 204 will stir the electrolyte during the rotation process, causing the electrolyte to flow, thereby breaking the bubbles.

[0046] S4, such as Figure 3 As shown, when the temperature of the aluminum-air battery assembly 2 is high, the temperature detected by the temperature sensor set inside the heat dissipation assembly 3 increases, and the heat dissipation fan 302 of the heat dissipation assembly 3 will quickly increase the power, and then the aluminum-air battery assembly 2 can be cooled. Figures 9 to 12As shown, when the temperature-sensitive elastic member 604 pushes the connecting member 605, the connecting member 605 no longer blocks the air hole 2031, so that the air pipe 2032 is connected to the mounting groove 601 through the air hole 2031, thereby being able to dissipate heat for the components inside the mounting groove 601;

[0047] S5, such as Figures 9 to 12 As shown, when the temperature of the aluminum-air battery assembly 2 returns to normal, the temperature-sensitive elastic member 604 will pull back the connecting member 605, so that the connecting member 605 blocks the air hole 2031 and cuts off the connection between the air pipe 2032 and the mounting groove 601. At the same time, through the rack 602, the gear shaft 603 drives the insulating frame 205 and the aluminum plate 204 to rotate in the opposite direction, so that the multiple insulating frames 205 rotate back to a flush state and allow the aluminum plate 204 to continue to maintain chemical reaction.

[0048] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
