摘要：

A reduced graphene oxide encapsulating Fe6Ni20Co2Mn2Cu1.5@rGO catalyst is prepared using a Joule heating strategy. The graphene-coated layer with high crystallinity enhances the stability of the crystal structure, resulting in superior OER activity. Rechargeable zinc-air batteries with Fe6Ni20Co2Mn2Cu1.5@rGO demonstrate remarkable performance, boasting a high specific capacity of 800 mA h gZn-1, an impressive peak power density of 154.612 mW cm-2, and a cycle life of 300 hours at a current density of 10 mA cm-2. In this study, we design a multi-layer reduced graphene oxide catalyst with high crystallinity encapsulating a high-entropy alloy structure.
