The cyclic stability of the MnO cathodes for rechargeable zinc ion batteries have substantial obstacles due to Mn disproportionation produces Mn caused by Jahn Teller lattice distortion effect in the process of Zn inter/deintercalation. This mini review summarized bulk-phase and interface stability strategies of manganese oxide cathodes for aqueous Zn-MnO batteries from the regulation of bulk electronic state of manganese oxide improves its structural stability and the formation of beneficial SEI layer at the interface of electrolyte. It provides theoretical support for the design of manganese oxide cathode materials for aqueous zinc ion batteries with high stability.
由于在锌嵌入/脱嵌过程中，Jahn-Teller晶格畸变效应导致锰歧化生成锰，可充电锌离子电池的MnO阴极的循环稳定性存在重大障碍。本综述从调节氧化锰的体电子态以提高其结构稳定性以及在电解质界面形成有益的固体电解质界面（SEI）层两个方面，总结了水系Zn-MnO电池氧化锰阴极的体相和界面稳定性策略。它为设计具有高稳定性的水系锌离子电池氧化锰阴极材料提供了理论支持。
