the synthesis of Chevrel phase Mo6S8 nanocubes
and its application as the anode material for rechargeable Zn-ion
batteries. Mo6S8 can host Zn2+ ions
reversibly in both aqueous and nonaqueous electrolytes with specific
capacities around 90 mAh/g, and exhibited remarkable intercalation
kinetics and cyclic stability. In addition, we assembled full cells
by integrating Mo6S8 anodes with zinc-polyiodide
(I–/I3–)–based
catholytes, and demonstrated that such full cells were also able to
deliver outstanding rate performance and cyclic stability. This first
demonstration of a zinc-intercalating anode could inspire the design
of advanced Zn-ion batteries.
