  • Metal air battery and method of manufacturing the same
    Patent number: 10720685
    Abstract: A metal air battery according to one embodiment of the present invention includes a pair of air cathodes having planar shapes respectively, which have a first bonding portion bonded along edges of the pair of the air cathodes and are disposed to face each other; a pair of separators disposed in contact with the pair of the air cathodes; an anode having a planar shape disposed between the pair of the separators and electrically insulated from the pair of the air cathodes; and then a zinc gel disposed in an accommodation space between the pair of the air cathodes. The accommodation space is a space formed by elastic deformation of the pair of the air cathodes.
