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 electrolyte flow part for inducing electrolyte to flow inside the zinc gel negative electrode part. The oxygen discharging efficiency that remains in the zinc gel negative electrode part and is not smoothly discharged to the outside can be improved, and thus charging performance of the zinc-air secondary battery can be improved.
