Abstract: The invention discloses a unit body of metal air battery, which can solve the problem of the nonuniformity of velocity in the electrolyte, ensure the internal electrolyte uniformly distributed, the residue in a cavity of a battery can be carried away fully in the electrolyte circulation and reflow process, injecting electrolyte in the whole metal air batteries can be realized only by a set of water injection equipment, greatly save the cost of manpower and material resources. The upper center of a housing has an upper hole and the lower center of a housing has a bottom hole. There is a slope inclined toward the inside in a cavity. There is a lower through hole at the lowest end of a slope. A lower through hole is communicated with a bottom hole of a housing. Both sides of a bottom hole and an upper hole have a mating surface groove, in which a sealing ring of a housing is placed. An upper sealing ring is fixed on a sealing plug.

Abstract: A metal air fuel cell is provided. The metal air fuel cell includes a plurality of unit bodies arranged in parallel in a battery housing. Each of the plurality of unit bodies includes a housing, a front cover, an alloy plate, a sealing ring, a battery cover, an upper copper electrode, an air electrode, and a back cover. The upper copper electrode, the battery cover and the alloy plate are connected by bolts to form a metal fuel monomer.

Abstract: A small metal air cell can be easy to carry, easy to use, and can be well integrated with some existing standard battery products. It includes an electric core, wires, an upper cover, an output negative electrode, a negative electrode presser, a positive pole press, an output positive pole, a housing. The cores grouped are placed in a housing, and the bottom of a housing has a ventilation hole. Each core includes an air electrode, an absorbent cotton, an alloy rod, and an absorbent cotton is encapsulated outside an alloy rod by an air electrode. Each electric core is connected through a wire, and a total positive leading out line and a total negative leading out line are reserved. An output positive pole and an output negative pole are installed on an upper cover.

Abstract: The invention discloses a metal air fuel cell, which can replace a single metal fuel conveniently, making the whole product more convenient and more conducive to maintenance in the process of use, so as to increase the service life of the product and enhance the user experience of the product. The metal air fuel cell includes several cell bodies. Each unit body comprises a housing, a front cover, an alloy plate, a sealing ring, a battery cover, an upper copper electrode, an air electrode, a back cover. The front part of a housing is sealed by the bonding of a front cover and an air electrode to form a cavity between a housing and the bonded front cover and an air electrode. The rear part of a housing is sealed by the bonding of a back cover and an air electrode to form a cavity between a housing and the bonded back cover and an air electrode. A sealing ring is placed in a groove i of a battery cover.
