The invention discloses a zinc air battery structure which comprises an upper shell and a lower shell welded with the upper shell through ultrasonic waves. A first sealing ring and a second sealing ring are arranged between the upper shell and an anode material and between the lower shell and the anode material respectively, and the space between the upper shell and the lower shell is filled with an epoxy resin ring capable of internally casting the outer end of the anode material. The zinc air battery structure is simple and good in sealing effect. The invention further discloses a zinc air battery packaging process which includes the steps: A, adhering the first sealing ring and the second sealing ring on the upper shell and the lower shell, and mounting a cathode collector plate and a cathode rivet in the upper shell; B, placing the anode material between the first sealing ring and the second sealing ring, and welding the upper shell and the lower shell through the ultrasonic waves; C, filling epoxy resin between the upper shell and the lower shell, and casting the outer end of the anode material in the epoxy resin; D, filling zinc gel into the shells; E, sealing a gel filling hole in the upper shell. The packaging process can prevent liquid leakage.
Description
【Technical field】 [0001] The invention relates to a zinc-air battery structure, and also relates to a zinc-air battery packaging process. 【Background technique】 [0002] Zinc-air batteries are generally made into a disposable power supply. Its positive electrode (air electrode) uses oxygen in the air as the active material, the negative electrode active material is metal zinc powder, and the electrolyte is KOH aqueous solution. Zinc-air battery has high specific energy (theoretical specific energy is 1350Wh / Kg, actual specific energy can reach 350Wh / Kg), and it is one of the battery varieties with the highest specific energy currently in use. And the voltage is stable, the operating temperature range is wide (-30 ~ 60 ℃), the working time is long, and there is no pollution. During the use, it will not pollute the human body and the environment, and the used waste batteries will not pollute the environment. Compared with other types of batteries, its energy density has obvio...
