Description

Technical Field

[0001] The present invention relates to the technical field of metal fuel cells, and more specifically to a novel metal fuel cell. Background Art

[0002] Metal fuel cells, as an innovative power generation device, are characterized by the use of metal as the negative electrode, while the air catalytic electrode plays the role of the positive electrode. In this type of battery, a variety of metals such as lithium, calcium, magnesium, aluminum, zinc, and iron can be used as negative electrode materials, but magnesium, aluminum, and zinc have become the first choice for negative electrode materials due to their excellent stability and high energy density. When magnesium, aluminum, and zinc are used as negative electrodes, water-soluble electrolytes are usually used as electrolytes. This electrolyte uses water as the active ingredient and is divided into alkaline or neutral types according to the difference in composition. Alkaline electrolytes are mainly composed of KOH or NaOH solutions, while neutral electrolytes are mostly KCl or NaCl solutions, and seawater can even be used directly as an electrolyte.

[0003] Aluminum-air fuel cells, as the leader in the metal fuel cell family, use aluminum as the negative electrode, and their energy density is second only to lithium-air batteries. With its safety, environmental protection and excellent environmental adaptability, it shows great development potential. In addition, aluminum-air fuel is inexpensive, easy to store for a long time, and the battery activates quickly, so it is very suitable as a power source for lighting equipment or small appliances.

[0004] During the discharge process of a metal fuel cell, the negative electrode metal will gradually be consumed to form metal oxides or hydroxides and enter the electrolyte, such as Al(OH)3 and Mg(OH)2. These reaction products will reduce the activity of the electrolyte, affect the discharge efficiency of the battery, and even hinder the discharge reaction in severe cases. Therefore, in order to ensure the efficient operation of the battery, the electrolyte needs to be replaced regularly to remove these reaction products. At the same time, side reactions may also occur between the metal electrode and the electrolyte, producing a small amount of hydrogen. These gases need to be discharged in time to avoid excessive pressure inside the battery. When the battery is not in operation, the metal electrode will still slowly react with the electrolyte. In order to avoid the consumption of the metal electrode, the electrolyte is usually separated from the metal electrode. When it is needed, the electrolyte is added to activate the battery.

[0005] When designing metal fuel cells, an open system is usually used, that is, the battery is not completely sealed. The design needs to take into account the reservation of exhaust holes, the convenient replacement of electrolytes, and the replacement of metal electrodes. At the same time, since the air electrode needs to consume oxygen in the air, it is also necessary to ensure that the air electrode remains connected to the atmosphere.

[0006] Traditional battery designs often include a battery reaction chamber, in which the air electrode is located outside the chamber for easy contact with the atmosphere, while the metal electrode is placed in the center of the chamber for easy contact with the electrolyte. This design is compact and simple, but limited by the integrated design of the air electrode and the chamber, the shape of the chamber can usually only be rectangular. In addition, once the chamber is damaged, the entire battery will be unusable because the air electrode cannot be replaced. At the same time, due to the limitations of the cavity structure and space, there are many inconveniences in adding electrolyte and cleaning the reaction products inside the battery. Especially when building a battery pack, in order to reduce the volume of the battery stack, the reaction chamber is usually designed to be smaller, and each single cell is connected by a pipe. This design has high resistance and is inconvenient when adding electrolyte and slag removal, especially when there is a lot of solid slag inside the battery, it is easy to cause blockage of the pipe and the chamber, resulting in the scrapping of the entire battery pack. In addition, in order to facilitate the injection of electrolyte into the battery stack, each single cell is usually connected by a pipe. These pipes filled with electrolyte are equivalent to wires, connecting each single cell to form an internal circuit, resulting in self-discharge of the battery stack, reduced discharge efficiency and severe heat generation. In view of this, we propose a new type of metal fuel cell. Summary of the invention

By arranging an annular inclined surface 2033 in the ventilation shell 2021, the docking tube 1041 can be more conveniently inserted into the ventilation shell 2021 during installation, thereby reducing the installation difficulty of the device. At the same time, the anti-leakage ring 2024 in the ventilation shell 2021 can ensure the friction between the docking tube 1041 and the ventilation shell 2021, thereby ensuring the sealing and stability after assembly.

[0051] Working principle: This embodiment provides a new type of metal fuel cell. When the device is working, the battery cavity 101 is removed, and an appropriate amount of electrolyte is injected into the battery cavity 101. Then, the battery shell 2011 containing the air electrode 102 and the aluminum electrode 103 is installed in the battery cavity 101, and the battery shell 2011 is reinforced. When the air electrode 102 and the aluminum electrode 103 are connected by the electrolyte, the battery can supply power to the outside. When it is necessary to replace the electrolyte or clean the inside of the battery, it is only necessary to remove the battery cavity 101, pour out the waste electrolyte, and rinse the battery cavity 101 and the electrode surface. After rinsing, the battery cavity 101 is installed back, and the battery can be stored for a long time.

[0052] When disassembling and replacing the device, it is only necessary to disassemble the connection between the shell component 201 and the battery cavity 101, and then the shell component 201 and the components connected to the shell component 201 can be completely removed. When reinstalling, the four ventilation components 202 will enter the two docking components 104 respectively and complete the connection, so that the two upper sealing components 203 are connected with the two lower sealing components 203 through the docking components 104, so that the gas can enter along the shell component 201 and then be discharged, and the air will not contact the electrolyte in the battery cavity 101 and the aluminum electrode 103;

[0053] During installation, the air electrode 102 and the aluminum electrode 103 are inserted into the slot 2013, and then the battery housing 2011 is inserted into the battery cavity 101. When the sealing tube 2031 is inserted, it will enter the butt joint tube 1041, and the sealing tube 2031 will squeeze the push plate 1046, so that the push plate 1046 is squeezed by the slide bar 1043 to move into the butt joint tube 1041. At this time, the air in the sealing tube 2031 will enter the gap between the sealing plate and the butt joint tube 1041 along the air leakage groove 1047 on the surface of the push plate 1046, and the butt joint tube 1041 will also squeeze and squeeze the air in the sealing tube 2031. The pressing plate 20236 causes the squeezing rod 20232 to discharge the gas in the sealing tube 20231 into the expansion airbag 2022, so that the expansion airbag 2022 expands and seals the contact position between the butt joint tube 1041 and the sealing tube 2031, and the connecting rod 2034 will also move backward due to squeezing the push plate 1046, thereby pushing the piston plate 2035 to be misplaced. At this time, the outside air can enter along the air intake shell 2014 and along the sealing tube 2031 into the butt joint tube 1041, and then be discharged along the ventilation tube 204 and the exhaust port 2012, completing the cycle;

[0054] During disassembly, the battery housing 2011 is disassembled and then removed. During the removal process, the sealing tube 2031 and the connecting rod 2034 are gradually separated, so that the first spring 1044 and the second spring 2036 push the piston plate 2035 and the sealing sheet 1045 to gradually return to their original positions, thereby lowering the sealing of the connecting tube 1041 and the sealing tube 2031 to prevent the electrolyte from entering the air circulation space during the disassembly process.

[0055] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
