Preparation of Graphene-based Noble Metal Catalysts and their Effects on the Performance of Lithium-oxygen Batteries AITranslate
Abstract AITranslate
Lithium-oxygen batteries,as a new type of battery system with ultra-high theoretical specific energy density,have good application prospects in the field of electric vehicles.Reduced graphene oxide was prepared by modified Hummers method and thermal expansion method,and different noble metals Ru,Ir,Au and Ag were loaded by impregnation reduction method,and the effect of graphene catalysts with different noble metals on the performance of lithium-oxygen batteries were studied.The results show that the reversibility and charge-discharge cycle stability of lithium-oxygen batteries with Ru/RGO and Ir/RGO catalysts with high catalytic activity for oxygen precipitation are better than those of lithium-oxygen batteries with Ag/RGO and Au/RGO catalysts.
