Abstract

The present invention provides an electrode structure including a first electrode unit, a second electrode unit, and a first insulating frame, and each electrode unit has an adjacent structure. The first electrode unit has a ventilation space inside and has a positive electrode for an air battery on the outer surface of the ventilation surface of the conductive substrate having a ventilation surface. The second electrode unit includes an air battery negative electrode on the outer surface of the conductive substrate. The first insulating frame separates and joins the adjacent electrode units so that the air battery positive electrodes and the air battery negative electrodes of the adjacent electrode units face each other, and together with the adjacent electrode units forms the electrolytic solution storage portion.

Description

technical field [0001] The present invention relates to an electrode structure, an air battery, and an air battery pack. More specifically, the present invention relates to an electrode structure for an air battery capable of reducing collector resistance and improving output, an air battery and an air battery pack including the electrode structure. Background technique [0002] An air battery is a battery that uses oxygen in the air as a positive electrode active material, and uses metals such as aluminum (Al), iron (Fe), and zinc (Zn) as a negative electrode active material. Furthermore, since the air battery does not require a positive electrode active material in the battery container, it has a high energy density and can also be reduced in size and weight. Therefore, air batteries are expected to be used as power sources for portable devices, and further, as power sources for driving electric vehicles and the like. In addition, since the electrolyte solution is stored...
