| 摘 要： | Low-cost and high-energy-density manganese-based compounds are promising cathode materials for rechargeable aqueous zinc-ion batteries（AZIBs）, however, they often experience cycling instability issues and inferior rate capability. Herein, we report a new layered manganese-based cathode material, ZnMn3O7（ZMO）, which possesses a large interlayer spacing of 4.8 ? and allows the intercalation of ～1.23 Zn-ions per formula unit（corresponding to a capacity of ～170 m Ah/g）. Importa...
