This work describes 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.
