MoS₂/SnS₂ nanocomposite as stable sodium-ion battery anode

Abstract

MoS 2 /SnS 2 composite material with satisfactory electrochemical performance has been prepared through a facile two-step hydrothermal method followed by high temperature sintering. The as-synthesized nanocomposite exhibits both excellent reversible capacity and improved cycling durability as the anode material of sodium ion batteries. Based on electrochemical test results, MoS 2 /SnS 2 shows an incipient capacity of 750[Formula: see text]mAh/g and a capacity reservation of 600[Formula: see text]mAh/g after 100 cycles at the current of 0.1[Formula: see text]A/g. Such a combination of MoS 2 nanosheets and SnS 2 nanoparticles alleviates the agglomeration problem and attributes strong synergic effect, making MoS 2 /SnS 2 composite a potential sodium ion battery anode.
