Aqueous multivalent metal-ion batteries (AMMIBs), with their unique characteristics such as high safety, low cost, and multiple electron transfers, have been widely applied in the fields of wearable devices, consumer electronics, and electric vehicles. Layered-structure materials are regarded as promising electrode materials for AMMIBs because of their tunable interlayer spacing and the ability to accommodate other guest ions or molecules. However, their large-scale application is impeded by several issues, including the dissolution, structural instability, low conductivity, and poor electrochemical properties of active materials. This review highlights various strategies aimed to solve these issues for layered-structure cathode materials. It begins with a brief introduction on the fundamental characteristics of the AMMIBs and challenges faced by the layered-structure materials. Subsequently, several effective strategies are elaborated in detail from the point of view of morphology, structure of the cathodes, and electrolyte to provide further insights into the design and optimization of high-performance AMMIBs. Lastly, a brief summary of the strengths and weaknesses of the above strategies is presented and focus is placed on the possible research direction in this field.

水性多价金属离子电池（AMMIB）具有诸如安全性高，成本低和多次电子转移等独特特征，已广泛应用于可穿戴设备，消费电子产品和电动汽车领域。层状结构的材料由于其可调节的层间间距以及容纳其他客体离子或分子的能力而被认为是AMMIB的有希望的电极材料。然而，它们的大规模应用受到若干问题的阻碍，包括溶解，活性物质的结构不稳定性，低电导率和不良的电化学性能。这篇综述重点介绍了旨在解决层状阴极材料这些问题的各种策略。首先简要介绍了AMMIB的基本特性以及分层结构材料面临的挑战。随后，从形态，阴极结构和电解质的角度详细阐述了几种有效的策略，以为高性能AMMIB的设计和优化提供进一步的见解。最后，简要介绍了上述策略的优缺点，并将重点放在该领域可能的研究方向上。
