摘      要：Irreversible reductive insertion of Zn2+transforms Mn3O4 such that the resulting Zn0.2Mn3O4 exhibits highly reversible storage properties of chloride ions,thus rendering Zn0.2Mn3O4 an excellent cathode of aqueous dual-ion *** Zn2+trapped,Zn0.2Mn3O4 delivers the chloride-storage capacity over 200 mAh/g at an average potential of 1.6 V vs Zn2+/Zn by reversibly forming a new ionic compound equivalent to *** quartz crystal microbalance results suggest chloride as the primary charge carrier in the reversible oxidative anion *** Mn3O4 anion-hosting cathode couples with Zn metal anode in a full-cell dual-ion battery,demonstrating stable cycling in practical pouch cells with an energy density of 150 Wh/kg based on the mass of both electrodes.
