Zinc-ion batteries (ZIBs) have recently attracted great interest and are regarded as a promising energy storage device due to their low cost, environmental friendliness, and superior safety. However, the development of suitable Zn-ion intercalation cathode materials remains a great challenge, resulting in unsatisfactory ZIBs that cannot meet commercial demands. Considering that spinel-type LiMnO has been shown to be a successful Li intercalation host, spinel-like ZnMnO (ZMO) is expected to be a good candidate for ZIBs cathodes. This paper first introduces the zinc storage mechanism of ZMO and then reviews the promotion of research progress in improving the interlayer spacing, structural stability, and diffusivity of ZMO, including the introduction of different intercalated ions, introduction of defects, and design of different morphologies and in combination with other materials. The development status and future research directions of ZMO-based ZIBs characterization and analysis techniques are summarized.
锌离子电池（ZIBs）由于其低成本、环保和优越的安全性，最近引起了极大的关注，被认为是一种很有前途的储能设备。然而，合适的 Zn 离子嵌入阴极材料的发展仍然是一个巨大的挑战，导致不能满足商业需求的不尽人意的 ZIBs。考虑到尖晶石型 LiMnO 已被证明是一种成功的 Li 嵌入主体，尖晶石型 ZnMnO（ZMO）有望成为 ZIBs 阴极的良好候选材料。本文首先介绍了 ZMO 的锌存储机制，然后综述了提高 ZMO 的层间距、结构稳定性和扩散率的研究进展的促进作用，包括引入不同的嵌入离子、引入缺陷以及设计不同的形态和与其他材料结合。总结了基于 ZMO 的 ZIBs 特性和分析技术的发展现状和未来研究方向。
