Advanced cobalt phosphide and derivatives air-cathode catalysts for zinc-air batteries

In recent years, there has been an urgent need for more efficient, lower-cost, and more stable Zinc-Air Batteries (ZABs) devices to meet the increasing demand for energy storage technology. Therefore, improving the air cathode catalyst is an unavoidable problem. This paper discusses the synthesis and application of cobalt phosphide materials, especially in ZABs air cathode catalysts (from 2019 to early 2024). The selected literature briefly evaluates the synthesis scheme and purpose of cobalt phosphide and its derivatives. Additionally, it reviews the performance of ZABs devices assembled with air cathode catalysts. Finally, it describes recent developments and provides prospects for future development. This work may provide some guidance for future studies on cobalt phosphide and its derivatives as air cathode catalysts.
