Abstract
(EN) Disclosed in the present invention is a high voltage rechargeable zinc-manganese battery. The structure of the zinc-manganese battery comprises a zinc electrode/alkaline electrolyte/ion exchange membrane/acid electrolyte/manganese dioxide electrode; the ion exchange membrane comprises a cation exchange membrane, an anion exchange membrane, or a proton exchange membrane. According to the present invention, by using a complex electrolyte system (alkaline electrolyte/ion exchange membrane/acid electrolyte), a high voltage rechargeable zinc-manganese battery is obtained; in the present invention, an open-circuit voltage reaching 2.7 V is obtained, the discharge voltage is greatly improved, the discharge capacity is also improved, and cyclic charge and discharge are implemented. The present invention has great scientific value, social benefits and economic benefits.
(FR) L'invention concerne une batterie zinc-manganèse rechargeable haute tension. La structure de ladite batterie zinc-manganèse comprend une électrode de zinc/un électrolyte alcalin/une membrane échangeuse d'ions/un électrolyte acide/une électrode de dioxyde de manganèse ; la membrane échangeuse d'ions comprend une membrane échangeuse de cations, une membrane échangeuse d'anions ou une membrane échangeuse de protons. Selon l'invention, la mise en oeuvre d'un système électrolytique complexe (électrolyte alcalin/membrane échangeuse d'ions/électrolyte acide) permet d'obtenir une batterie zinc-manganèse rechargeable haute tension. La présente invention permet également d'obtenir une tension en circuit ouvert atteignant 2,7 V, d'améliorer considérablement la tension de décharge et la capacité de décharge, et de mettre en oeuvre une charge et décharge cycliques. L'invention présente une grande valeur scientifique, des avantages sociaux, ainsi que des avantages économiques.
