چکیده مقاله
Among energy storage devices, metal-air batteries have the highest energy density [1]. The zinc-air option is a safe, eco-friendly, inexpensive, and simple method for different applications [2]. These batteries work by oxidizing zinc with oxygen, reducing O2 to complete the redox reaction [1]. There are several challenges in the development of zinc-air batteries, including the slow kinetics of the cathodic reaction and the adverse deposition of zinc oxide on the air cathode. The cathode catalyst must be such as to prevent the access of zinc ions [3]. In this study, a comparative study between the performance of a non-noble metal cathode and a cathode electrode containing 30%wt Pt/C was performed to investigate the effect of zinc oxide. Electrochemical investigations were performed by a three-electrode system and an LSV curves was used to compare the inherent activity and selectivity of the catalysts. According to the Figure 1, Fe-Co/kb showed significant selectivity in oxygen depletion and superior intrinsic activity in terms of volumetric flow density, as well as better performance in the presence of zinc oxide.
