Abrégé
(EN)
The invention discloses a high-voltage rechargeable zinc-manganese battery. The zinc-manganese battery structurally comprises a zinc electrode, alkaline electrolyte, an ion exchange membrane, acidic electrolyte and a manganese dioxide electrode, and the ion exchange membrane comprises a cation exchange membrane, an anion exchange membrane or a proton exchange membrane. According to the present invention, the high-voltage rechargeable zinc-manganese battery is obtained by using a composite electrolyte system (alkaline electrolyte/ion exchange membrane/acidic electrolyte), an open-circuit voltage as high as 2.7 V can be obtained, the discharge voltage is greatly improved, at the same time, the discharge capacity can be improved, and the cyclic charge and discharge can be carried out. The zinc-manganese battery has great scientific research value, social benefit and economic benefit.
