摘要：Utilization the high entropy concept to fabricate novel alloy system is an effective approach to enrich the anode materials and construct high effective energy storage device. In this work, the FeCoNiCrMn high entropy alloy with two-dimensional ultra-thin nanosheet structure was prepared via the salt-template method. The particular structure offers large specific surface area, abundant ions storage sites and robust structure. As an example application, our-designed FeCoNiCrMn high entropy alloy exhibits excellent electrochemical performance as the anode in lithium ion batteries. It displays the large specific capacity (1026.01 mAh/g after 120 cycling), high rate performance and long life-span at 2 A/g (>500 cycles). Most important, extensive characterizations prove that the Cr atom is a key factor to keep structure stability, while the Mn atom is an active metal to provide capacity, indicating that the cocktail effect plays great role on improving the energy storage performance of high entropy materials. Our work provides a new pathway to develop high entropy materials and drives the development of the alternative anode for energy storage device.
