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-/I-3(-))-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.
