Lithium ion battery is a technology on its way of closing on its theoretical bounds. In this sense, secondary zinc air batteries are a strong contender as a next generation power source. As great possibilities are hidden in this particular system as their beneficial properties include: larger energy density, lesser tariffs on the environment and cheaper materials. Although with such aspects, the cyclic stability has been a constant undermining factor. Preceding works have been on the understanding of the electrode properties, but not much insight has been given to the intermediate components; the electrolyte and the separator. Herein the presented work shows some light to the influential effects of the zincate ion. It has been observed that the crossover of the zincate ion is a significant factor effecting the life of a secondary zinc air battery. Furthermore a facile mitigation strategy has been providing using a anion exchange membrane.

Several studies have focused on rechargeable zinc–air batteries. Among them, the formation of zincate ions has been studied to enhance the reversibility of the zinc anode. In this study, zinc compounds, such as zinc oxide, chloride, and acetate, showed different solubility in KOH; this is related to the generation of zincate ions. A full-cell test was carried out to compare the electrochemical properties of electrodes. Zinc oxide has a high second discharge capacity of 178 mAh/g. To increase the solubility, the particle size of microsized ZnO was changed to nanosized ZnO. In addition, in the full-cell test, nanosized ZnO showed a higher cycle capacity than microsized ZnO. The reduction peaks were indicated clearly until 10 cycles in the three-electrochemical cell. Therefore, it is essential that microsized ZnO be converted easily to zincate ions.
