Manganese‐based oxide is arguably one of the most well‐studied cathode materials for zinc‐ion battery (ZIB) due to its wide oxidation states, cost‐effectiveness, and matured synthesis process. As a result, there are numerous reports that show significant strides in the progress of Mn‐based oxides as ZIB cathode. However, ironically, due to the sheer number of Mn‐based oxides that have been published in recent years, there remain certain contemplations with regards to the electrochemical performance of each type of Mn‐based oxides and their performance comparison among various Mn polymorphs and oxidation states. Thus, to provide a clearer indication of the development of Mn‐based oxides, the recent progress in Mn‐based oxides as ZIB cathode was summarized systematically in this Review. More specifically, (1) the classification of Mn‐based oxides based on the oxidation states (i. e., MnO₂, Mn₃O₄, Mn₂O₃, and MnO), (2) their respective polymorphs (i. e., α‐MnO₂ and δ‐MnO₂) as ZIB cathode, (3) the modification strategies commonly employed to enhance the performance, and (4) the effects of these modification strategies on the performance enhancement were reviewed. Lastly, perspectives and outlook of Mn‐based oxides as ZIB cathode were discussed at the end of this Review.

锰基氧化物作为锌离子电池正极的最新进展

锰氧化物由于其广泛的氧化态，成本效益和成熟的合成工艺，可以说是研究最深入的锌离子电池正极材料之一。结果，有许多报告显示，锰基氧化物作为ZIB阴极的发展取得了重大进展。然而，具有讽刺意味的是，由于近年来发表的锰基氧化物数量众多，因此对于每种类型的锰基氧化物的电化学性能以及它们在各种锰多晶型物和氧化物之间的性能比较仍存在某些思考。状态。因此，为更清楚地表明锰基氧化物的发展趋势，本综述系统地总结了作为ZIB阴极的锰基氧化物的最新进展。进一步来说，₂，锰₃ ö ₄，锰₂ ö ₃和MnO），（2）它们各自的多晶型物（即，α-MnO的₂和δ-的MnO ₂）作为ZIB阴极;（3）通常用于增强的修改策略性能，以及（4）这些修改策略对性能增强的影响。最后，在本综述的结尾讨论了锰基氧化物作为ZIB阴极的观点和前景。
