Abstract

Three dimensional metal carbide MXene/reduced graphene oxide hybrid nanosheets were prepared and applied as a cathode host material for lithium-sulfur batteries. The composites cathodes were obtained through a facile and effective two-step liquid phase impregnation method. Owing to unique 3D layer structure and functional 2D surfaces of MXene and reduced graphene oxide nanosheets for effectively trapping sulfur and lithium polysulfides, MXene/reduced graphene oxide/sulfur composites cathodes delivered a high initial capacity of 1144.2 mAh g-1 at 0.5 C and a high level of capacity retention of of 878.4 mAh g-1 after 300 cycles. We demonstrated that hybrid metal carbide MXene/reduced graphene oxide nanosheets could be a promising cathode host material for lithium-sulfur batteries.
