Zinc-air rechargeable batteries are a promising alternative for sustainable energy storage, thanks to their high energy density and the use of abundant materials with low environmental impact, as well as their safe operation. However, they still have some technological limitations that prevent their current capacity from being completely satisfactory, especially because of the degradation that occurs at the cathode and corrosion of the anode, which ultimately limit both the reversibility and a long battery life. The proposed methodology allows to protect the (electro)catalytic centers. In this way, it is intended to extend its useful life, improving both its behavior in real conditions, and solving the existing problems in the electrodes. Thus, based on this technology, new electrodes will be manufactured that will later be tested in pre-industrial battery prototypes
