Description

Technical Field

[0001] The invention relates to the technical field of metal fuel cells, and in particular to a glue stick type portable air battery monomer device. Background Art

[0002] The energy storage battery technology on the current market is mainly dominated by lithium batteries, which have demonstrated excellent performance in many fields. However, when lithium batteries are stored or not in use, they will spontaneously undergo chemical reactions inside, causing the battery power to gradually lose, that is, there is a problem of self-discharge, which will seriously affect the battery's energy retention and long-term storage capabilities.

[0003] In this context, air batteries stand out with their unique advantages. When in storage or not in use, the metal anode, air cathode and electrolyte of the air battery are in a physically separated state, blocking the conditions for chemical reactions, so there is almost no self-discharge problem. This means that the air battery can still maintain a high power reserve when not in use for a long time, providing a reliable guarantee for emergency use. When discharge is required, the battery can be started quickly by simply mixing the three together to meet immediate power needs. This feature gives air batteries extremely broad application prospects under conditions that require long-term backup or emergency use.

[0004] However, despite the many advantages of air batteries, they still face some challenges in the process of market promotion and popularization. In the actual application of traditional air batteries, problems such as electrolyte leakage and inconvenience in carrying and use often occur, which will seriously affect the use effect of the battery. In extreme special scenarios such as field surveys and emergency rescue, there are often key requirements for battery products to be light and easy to use, but the structure of traditional batteries is often too complicated and heavy, and still cannot fully meet the use needs.

[0005] Therefore, it is of great significance to promote the popularization and application of aluminum-air batteries in the power market by carrying out technical innovation and optimizing design to address the problems existing in the practical application of air batteries and improving their portability and ease of use. Summary of the invention

[0019] This embodiment provides a glue stick type portable air battery monomer device, such as Figure 1-3As shown, it includes: a rotating mechanism, a shell 2 and an electrolyte storage chamber 3, the rotating mechanism includes a knob 1, the knob 1 is provided with a hollow spiral rod 5, in order to further fix the hollow spiral rod 5, a spiral rod base 4 can be provided between the knob 1 and the hollow spiral rod, the hollow spiral rod 5 is in the shape of a hollow cylinder, and the knob 1 and the spiral rod base 4 are provided with an air inlet communicated with the hollow spiral rod. The knob 1, the spiral rod base 4 and the hollow spiral rod 5 can be integrally processed and formed, and the knob 1, the spiral rod base 4 and the hollow spiral rod 5 have an air passage; the knob 1 and the spiral rod base 4 can also be provided with a through hole, and the hollow spiral rod 5 can also be inserted into the through hole. When the knob 1 is rotated, the knob 1 drives the spiral rod base 4 and the hollow spiral rod 5 to perform spiral motion synchronously. The hollow spiral rod 5 is sleeved with a spiral barrel base 6, and the center position of the spiral barrel base 6 is provided with a threaded hole adapted to the thread of the hollow spiral rod 5, and the hollow spiral rod 5 is rotatably connected with the spiral barrel base 6 through threaded matching. The lower end surface of the spiral drum base 6 is connected with an annular metal anode 11 and an air cathode membrane 12. The air cathode membrane is arranged below the threaded hole of the spiral drum base. The air cathode membrane 12 is a semi-enclosed structure. The upper end of the air cathode membrane is open, and there is an air passage inside, and the lower end is closed. The hollow spiral rod 5 can pass through the spiral drum base and extend into the air passage of the air cathode membrane 12. The air cathode membrane 12 and the metal anode 11 form the cavity of the battery cell. The battery cell is provided with air through the air cathode membrane 12 and the hollow spiral rod 5. The air cathode membrane 12 adopts a polytetrafluoroethylene (PTFE) alkali-proof breathable membrane or a polyvinylidene fluoride (PVDF) alkali-proof air membrane. This membrane material can effectively prevent the penetration of alkali solution and maintain air circulation.

[0020] A matching sliding structure is provided between the metal anode 11 and the housing 2. Figure 2 As shown, the outer side of the metal anode 11 is provided with one or more vertical grooves 7, and the inner circumference of the shell 2 is provided with vertical protrusions adapted thereto. The outer contour of the protrusions on the inner circumference of the shell 2 matches the inner contour of the groove 7 on the outer side of the metal anode 11. Conversely, the outer side of the metal anode 11 may be provided with one or more vertical protrusions, and the inner circumference of the shell 2 may be provided with vertical grooves adapted thereto. In this way, when the knob 1 is turned, the spiral rod base 4 and the hollow spiral rod 5 can rotate synchronously, and the rotation of the hollow spiral rod 5 will cause the spiral cylinder base 6 to drive the metal anode 11 and the air cathode membrane 12 to move up and down along the groove 7. (The "inside" of the air cathode membrane 12, the metal anode 11 and the shell 2 mentioned above refers to the surface facing the center direction of the spiral cylinder base 6, and the "outside" of the air cathode membrane 12 and the metal anode 11 refers to the surface facing the direction of the outer edge of the spiral cylinder base 6.) The lower part of the shell 2 is provided with an electrolyte storage chamber 3, and the electrolyte storage chamber 3 is used to contain electrolyte 10. In order to highlight the integrity and sealing of the device, the bottom cavity of the shell 2 can be used as the electrolyte storage chamber 3; in order to highlight the flexibility and maintenance convenience of the device, the electrolyte storage chamber 3 can be separated from the shell 2, and the electrolyte storage chamber 3 is provided at the bottom of the shell 2. The user can choose to replace only the electrode part or only the electrolyte 10 according to the application requirements, which reduces the number of parts that need to be replaced during battery maintenance and reduces the maintenance cost.

[0021] A positive metal connecting piece 14 and a negative metal connecting piece 13 are provided in the electrolyte storage chamber 3, and the positive and negative metal connecting pieces are used to connect to the external circuit of the battery. In order to improve the stability of the power output of the device of the present invention, an anode metal connector 8 is provided below the metal anode 11, and a cathode metal connector 15 is provided below the air cathode membrane 12. Preferably, the length of the air cathode membrane 12 is equal to the length of the metal anode 11.

[0022] In order to improve the portability of the device and prevent leakage of the electrolyte 10, a sealing ring 16 is provided at the top of the electrolyte storage chamber 3. The sealing ring 16 is used to enhance the airtightness of the connection between the electrolyte storage chamber 3 and the shell 2. An electrolyte storage membrane 9 is provided in the electrolyte storage chamber 3, and the contact end of the anode metal connector 8 and the positive metal connecting piece 14, and the contact end of the cathode metal connector 15 and the negative metal connecting piece 13 are all set as sharp tips. When the battery is turned on, the knob 1 is turned, and the metal anode 11, the air cathode membrane 12, the anode metal connector 8 and the cathode metal connector 15 move downward synchronously. The anode metal connector 8 and the cathode metal connector 15 will first contact the electrolyte storage membrane 9. At this time, the tips of the anode metal connector 8 and the cathode metal connector 15 have the effect of metal cutting blades and can pierce the electrolyte storage membrane 9.

[0023] Furthermore, the metal anode 11 in the present application may be made of air battery anode materials such as aluminum, magnesium, zinc, lithium, sodium, etc.

[0024] The method of using the device of the present invention is as follows Figure 4 As shown: When the monomer is activated, the knob 1 is turned forward to drive the hollow spiral rod 5 to rotate, and the hollow spiral rod 5 and the spiral barrel base 6 rotate relative to each other through threaded cooperation. The spiral barrel base 6 drives the metal anode 11 and the air cathode membrane 12 to move downward along the groove 7. The anode metal connector 8 and the cathode metal connector 15 at the ends of the metal anode 11 and the air cathode membrane 12 pierce the electrolyte storage membrane 9, and the metal anode 11 and the air cathode membrane 12 are immersed in the electrolyte storage chamber 3, and the battery begins to undergo a chemical reaction.

[0025] Continue to rotate the knob 1 forward until the metal anode 11 and the air cathode membrane 12 are rotated to the limit position, that is, the anode metal connector 8 and the cathode metal connector 15 are in contact with the positive metal connector 14 and the negative metal connector 13 respectively, and the battery cell becomes a conductive circuit to supply power to the outside. In order to meet the power supply requirements of voltage and current in different application scenarios, multiple negative metal connectors 13 and positive metal connectors 14 of the device of the present invention can be connected in series and parallel to provide power to the outside.

[0026] After completing the power supply task, turn the knob 1 in the opposite direction to move the spiral barrel base 6 upward, and the anode metal connector 8 and the cathode metal connector 15 are separated from the positive metal connecting piece 14 and the negative metal connecting piece 13 respectively. The metal anode 11 and the air cathode membrane 12 are separated from the electrolyte 10, and the chemical reaction ends, and the power supply ends.

[0027] If it is used again in a short period of time, the knob 1 can be turned forward again to supply power.

[0028] The present invention can be set up in a larger volume and arranged in special places such as outdoors, mountains, and islands, or it can be made into a smaller volume for easy carrying. In the event of an emergency, when other power sources are exhausted and an emergency power source is needed, a glue stick-type portable aluminum-air battery cell device can be used. Before activation, due to the design of a glue stick-type cylindrical structure, the battery cell and the electrolyte 10 are stored separately, and no chemical reaction occurs, so long-term storage can be achieved. After a single use, the power supply of the aluminum-air battery cell is cut off, and the cavity composed of the metal anode 11 and the air cathode film 12 can be rotated out of the electrolyte storage cavity 3 by rotating the spiral knob 1 in the opposite direction, and it can be used repeatedly in a short period of time to ensure the battery power supply effect.
