The influence of different air electrode structures to discharge characteristics in rechargeable Zn-air battery

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