Investigation of triple perovskite oxide-based bifunctional electrocatalyst for rechargeable Zn-air batteries.

This thesis focuses on improving zinc-air batteries, a promising next-generation energy storage system that is safe, low-cost, and environmentally friendly. A major challenge for these batteries is that the reactions involving oxygen are too slow, which reduces efficiency and stability. To solve this, I designed new catalyst materials called perovskite oxides, made from abundant and inexpensive elements. By carefully adjusting their structure and composition, I created catalysts that make the oxygen reactions faster, more stable, and longer-lasting. This research provides a pathway toward affordable, durable, and high-performance zinc-air batteries for future clean energy applications.
