Investigation of the cycling stability and energy storage properties of zinc titanate (ZnTiO3) perovskite material for zinc-air batteries

With the merits of advantageous structure, morphology, purity, composition, and porosity, perovskites are explored as bifunctional alternatives to replace precious metals in the application of zinc-air batteries (ZABs). In this work, a new perovskite material, ZnTiO3 (Zinc Titanate; ZTO), was developed and investigated for its performance in a rechargeable zinc-air battery (ZAB). The oxygen activities were also examined in alkaline solutions with O-2 and N-2 purging on the RDE (rotating disc electrode) system. The zinc-air cell so developed exhibits good performance with a specific capacity of 625 mA h g(-1) at a current density of 5 mA cm(-2). The rechargeable ZTO battery also shows high cycling stability with minimum fluctuations at 5 mA cm(-2) for 500 cycles, resulting in ZnTiO3 being a promising candidate for zinc-air batteries.
