Tartalmi kivonat:The rechargeable metal-air battery technology is a well-interested smart method for eco-friendly and sustainable energy storage. Both of the two order of magnitude lower global market price per tonne of Zn compared to lithium and the multiple theoretical and practical specific energy density of rechargeable ZAB compared to the worldwide Li-ion designs contributes the developing continuously of rechargeable Zn-air battery. The air electrode as a cathode has a vital role in increasing the discharge-charge performance in ZABs, therefore different layers-order air electrodes were assembled with the utilization of Ni-foam, graphite coating and carbon nanoparticles. The tri-layers cathode showed the highest voltage and performance values compared to the mono- (Ni-foam) and bi- (Ni-foam + graphite coating) layers architectures. The effect of electrolyte inorganic additives (e.g., 2 n/n% ZnCl2 and 0,05 wt% MnO2) was experienced especially at the no-load period.
