Effect of MXene on the Catalytic Performance of Bimetallic Catalysts for Zinc-Air Batteries
The development of cathode catalysts with high oxygen reduction and oxygen evolution performance,stable and low-cost is the key to the industrialization of zinc-air batteries.In this work,FeNiSNC7:3@MXene bimetallic composites were prepared as cathode catalysts for zinc-air batteries using FeCl3,NiCl2,ZnCl2 and formamide as raw materials,and the phase composition,microscopic morphology,elemental composition,electrochemical properties and battery properties were analyzed by hydrothermal-synthesis,high-temperature,carbonization,low-temperature vulcanization.The battery prepared by this catalytic material has a narrow voltage gap of 0.74 V and a peak power density of 179 mW/cm2 in the battery test,which provides a new idea for the combination of two-dimensional materials and non-noble metal catalysts to improve the performance of zinc-air battery catalysts.
