The water-absorbing material 3 of the present application serves as a reaction diaphragm between the air electrode 4 and the metal electrode 2 and is arranged between the two. When the electrolyte flows to the water-absorbing material 3, the electrolyte is filled between the metal electrode 2 and the air electrode 4 through the action of the water-absorbing material 3. At this time, the metal electrode 2 and the air electrode 4 begin to discharge under the action of the electrolyte and output electrical energy to the outside.

[0034] The term "Class 1" in the title of the subject of this application refers to the metal-air battery of this application, whose appearance structure is similar to the existing cylindrical Class 1 battery structure. For example, the appearance size of this application can be designed to be the same as the appearance structure of the existing Class 1 alkaline battery, so that the metal-air battery of this application can replace the existing Class 1 alkaline battery for practical application.

[0035] The metal-air battery of the present application is not particularly limited, and conventional technologies in the field can be selected, such as aluminum-air fuel cells, zinc-air fuel cells or magnesium-air batteries.

The material of the slot plug 5 of the present application can be made of rubber, plastic and other materials.

[0036] In one alternative embodiment, the end cover 102 and the main shell 101 can be a split structure.

[0037] In one embodiment, Figure 1-4 As shown, the side wall of the main shell 101 is provided with three openings 101a along the circumferential direction of the side wall of the main shell 101 near the two end covers 102; in one of the alternative embodiments, the side wall of the main shell 101 is provided with three openings 101a along the circumferential direction of the side wall of the main shell 101 near one of the end covers 102, and the side wall of the main shell 101 is not provided with an opening 101a near the other end cover 102.

[0038] In one embodiment, the slot plug 5 is provided on one of the end covers 102 , with its open end extending inwardly into the cavity of the main shell 101 , and the other closed end extending outwardly through the end cover 102 ; the slot plug 5 is not provided on the corresponding other end cover 102 .

[0039] In one embodiment, the metal-air battery is provided with two slot plugs 5, which are respectively arranged on the two end covers 102 of the main shell 101. The open ends of the two slot plugs 5 extend inwardly into the cavity of the main shell 101, and the other closed ends extend outwardly through the end covers 102.

[0040] In one embodiment, the outer surface of the side wall of the main shell 101 is a smooth circular surface, or an outer surface composed of at least one rectangular plane. When the outer surface of the side wall of the main shell 101 is a smooth circular surface, the outer shapes of the metal electrode 2, the water-absorbing material 3 and the air electrode 4 can all be designed to be circular. For the convenience of installation and maintenance, the outer surface of the side wall of the main shell 101 is composed of at least one rectangular plane, such as the outer surface of the main shell 101. Figure 1-4 As shown, the outer surface can be designed to be composed of three rectangular planes. Correspondingly, the metal electrode 2 and the air electrode 4 are designed to be rectangles of corresponding sizes, and the water-absorbing material 3 can be designed to be integrated because it is usually flexible or bendable.

[0041] In one embodiment, the metal-air battery further includes a positive electrode sheet 6 ; the positive electrode sheet 6 is fixed to the slot plug 5 and electrically connected to the air electrode 4 . The electrical connection between the positive electrode sheet 6 and the air electrode 4 is established in any manner. For example, a wire may be welded to ensure a reliable connection when the positive electrode sheet 6 moves; or a predetermined electrical contact strip may be extended from the positive electrode sheet 6 , such that when the positive electrode sheet 6 moves to a position corresponding to the opening 101a of the side wall of the main housing 101 and the through hole 5a of the slot plug 5 , the positive electrode sheet 6 contacts the air electrode 4 .

[0042] As a preferred technical solution, the metal-air battery further includes a negative electrode sheet 7; the negative electrode sheet 7 is fixed to the slot plug 5, and the negative electrode sheet 7 establishes an electrical connection with the metal electrode 2. There are no strict restrictions on the manner in which the electrical connection between the negative electrode sheet 7 and the metal electrode 2 is established; for example, a wire can be welded to ensure that the wire connection remains reliable when the negative electrode sheet 7 moves; or the negative electrode sheet 7 extends a preset electrical contact strip, that is, when the negative electrode sheet 7 moves to a position corresponding to the opening 101a of the side wall of the main shell 101 and the through hole 5a of the slot plug 5, the negative electrode sheet 7 contacts the metal electrode 2. The negative electrode sheet 7 of the present application is also provided with a pressing sheet 8 to serve as an insulator.

[0043] In one embodiment, the metal-air battery may further include a housing (not shown); the housing protects the internal structure and is provided with a plurality of ventilation holes to facilitate air inflow to the air electrode for electrochemical reaction. In another alternative embodiment, the metal-air battery main housing 101 further includes a sealing member in the gap between the end cap 102 and the cathode plate to prevent leakage of electrolyte from the water-absorbing material 3 through the gap.

[0044] The Class-1 metal-air battery of this utility model is designed for emergency and long-term disposable power consumption, providing a solution to replace traditional dry cells and secondary batteries. It is particularly suitable for application scenarios that require 1 to 72 hours of continuous power supply, such as in remote areas or emergency situations, which often face the problem of insufficient power supply. Compared with traditional batteries, this battery has a longer storage time and does not require maintenance, providing users with a reliable and long-lasting source of power. In addition, this battery is compatible with all devices that use two Class-1 batteries and is suitable for a variety of electrical devices with a voltage of ≤3V and a power of ≤1W.

[0045] The functional characteristics of the metal-air battery of the present invention include a wide open circuit voltage range of 3.0 to 4.5V, and an operating voltage and power range of 1 to 3V and 0.1 to 1W, respectively. The electrolyte contained in the cavity inside the main shell can support 1 to 12 hours of continuous power use, and by simply re-wetting the battery cell (i.e., the part composed of the metal electrode 2, the water-absorbing material 3, and the air electrode 4), the power use time can be extended by up to 60 hours; that is, by re-wetting (replenishing the electrolyte), the battery cell can provide up to 72 hours of power supply. The method of use is simple and intuitive, such as Figure 2 and Figure 4 As shown, in the initial state, the through-hole 5a of the slot plug 5 is misaligned with the opening 101a of the main housing 101, indicating a non-discharging state. During use, for example in a flashlight, the slot plug 5 is pushed by squeezing and tightening the flashlight cap, aligning the through-hole 5a of the slot plug 5 with the opening 101a of the main housing 101. This allows the electrolyte to flow into the absorbent cotton and trigger battery discharge. This design not only simplifies the use process but also provides users with the flexibility to quickly activate the battery as needed.
