A rechargeable aqueous manganese-ion battery based on intercalation chemistry.

ABSTRACT: Aqueous rechargeable metal batteries are intrinsically safe due to the utilization of low-cost and non-flammable water-based electrolyte solutions. However, the discharge voltages of these electrochemical energy storage systems are often limited, thus, resulting in unsatisfactory energy density. Therefore, it is of paramount importance to investigate alternative aqueous metal battery systems to improve the discharge voltage. Herein, we report reversible manganese-ion intercalation chemistry in an aqueous electrolyte solution, where inorganic and organic compounds act as positive electrode active materials for Mn²⁺ storage when coupled with a Mn/carbon composite negative electrode. In one case, the layered Mn_0.18V₂O₅·nH₂O inorganic cath
