Problems solved by technology
Positive and negative shells are usually made of hard materials such as steel shells or plastic shells. They are pressed and bonded together, resulting in poor sealing and easy gaps between them. The negative electrode includes zinc powder and electrolyte, and the electrolyte is easy to flow from positive Leakage of the gap between the negative electrode shell and the diaphragm causes battery fluid leakage, which poses safety problems in battery storage and use; in addition, hard shells such as steel shells or plastic shells are difficult to process, which increases manufacturing costs

Embodiment Construction
[0019] In order to better understand the essence of the present invention, the following will be described in detail in conjunction with specific examples and experiments.
[0020] The invention aims to provide a soft-packed zinc-air battery, which not only has good sealing performance and no liquid leakage, but also is easy to process and low in manufacturing cost.
[0021] Such as figure 1 As shown, a breathable waterproof membrane 13 and a diaphragm paper 15 are respectively arranged on both sides of a positive electrode 14, a first inner packaging film 12 is arranged on the outside of the breathable waterproof membrane 13, and a second inner packaging film 16 is arranged on the outer side of the diaphragm paper 15. On the outside, the first inner packaging film 12 and the second inner packaging film 16 are heat-press sealed, and the first inner packaging film 12 and the second inner packaging film 16 are hollow structures with air vents on them. The edge of the air vent 1...

Abstract
The invention discloses a soft zinc-packaged air battery which comprises an anode outer packaging film, a cathode outer packaging film, a first inner packaging film, a second inner packaging film, a ventilating waterproof film, an anode, a diaphragm paper and a cathode, wherein the anode outer packaging film, the first inner packaging film, the second inner packaging film and the cathode outer packaging film are successively overlapped and the outer edges thereof are hot-pressed and sealed; a ventilating window is arranged on the anode outer packaging film; ventilating holes corresponding to the ventilating window are formed on the first inner packaging film and the second inner packaging film; a ventilating hole edge of the first inner packaging film and the ventilating waterproof film are hot-pressed and sealed; the ventilating hole edge of the second inner packaging film and the diaphragm paper are hot-pressed and sealed; the anode is arranged between the ventilating waterproof film and the diaphragm paper; the cathode is arranged between the second inner packaging film and the cathode outer packaging film. The soft zinc-packaged air battery has excellent sealing property, is capable of preventing liquid leakage, is easy to process and is low in manufacturing cost.
Description
technical field [0001] The invention relates to the technical field of zinc-air batteries, in particular to a structure of a soft-packed zinc-air battery. Background technique [0002] Zinc-air battery is a kind of primary battery that uses activated carbon to absorb oxygen or pure oxygen in the air as the positive electrode active material, uses zinc as the negative electrode, and uses ammonium chloride or caustic alkali solution as the electrolyte, also known as zinc-oxygen battery. It has the advantages of high specific energy, stable working voltage, stable performance, abundant raw materials, low price and no environmental pollution. [0003] A zinc-air battery includes a positive electrode casing, a positive electrode, a diaphragm, a negative electrode, and a negative electrode casing; the positive electrode casing and the negative electrode casing are bonded together by sealing rings and glue, the positive electrode is placed in the positive electrode casing, the nega...
