An aqueous Zn/VS 2 battery is designed, which consists of a VS 2 cathode, a zinc anode, and a mild ZnSO 4 aqueous electrolyte. The battery delivers a high capacity, and exhibits long‐term cyclic stability due to the large layer spacing and high conductivity of VS 2 . A reversible insertion/extraction of Zn 2+ is observed during the discharge/charge process.
