Abstract
A zinc-air secondary battery includes a positive electrode, a negative electrode, a separation membrane interposed between the positive and negative electrodes, and an electrolyte accommodated between the positive and negative electrodes and submerging a part of the positive electrode. The separation membrane is a porous separation membrane having a plurality of through-holes, and the separation membrane is provided with through-holes. The sizes of the holes are smaller than the size of the potassium ions contained in the electrolyte. A plurality of adsorptive potassium ion particles are evenly attached on at least one side of the separation membrane to form an adsorptive potassium ion particle layer.
