Abstract
A zinc-air secondary battery includes an air positive electrode part, a separator, and a zinc gel negative electrode part in a case, provided with an air flow guiding part, disposed in one area of the case, for guiding the inflow of air to the air positive electrode part when discharging and for guiding the discharge of air when charging. When discharging, the inflow of air is guided to an air positive electrode part so that discharging performance (discharging output) can be improved by pressing, and when charging, discharging of air including oxygen present in the zinc-air secondary battery is guided and promoted by pressing inside the zinc-air secondary battery so that charging performance can be improved.
