作为下一代电化学储能技术，可充电镁基电池因其体积能量密度高、安全隐患低以及地壳资源丰富而受到广泛关注。虽然有一些评论总结和讨论了正极和负极材料的进展，但针对可充电镁基电池性能改进既具有代表性又具有独特性的材料设计策略进行全面而深刻的评论却很少。在这篇小综述中，从内部和外部两个方面对所有九种提高正极材料镁离子储存性能的材料设计策略和方法进行了全面的研究。材料设计理念尤为突出，重点关注设计“软”阴离子材料、嵌入溶剂化或络合离子、扩展层状正极材料的层间、将杂原子掺杂到晶格中、尺寸定制、设计亚稳相材料以及开发有机材料。为了获得更好的阳极，还积累和分析了基于人工夹层设计、高效电解质筛选和替代阳极探索的策略。总结了 Mg-S 和 Mg-Se 电池的策略进展。从实际应用的角度批判性地讨论了所有收集的材料设计策略和方法的优缺点。该小综述有望为如何合理提高可充电镁基电池的可靠性和可行性提供清晰的研究线索，并为镁基电池以及其他多价离子电池化学的未来研究提供一些见解。
As a next-generation electrochemical energy storage technology, rechargeable magnesium (Mg)-based batteries have attracted wide attention because they possess a high volumetric energy density, low safety concern, and abundant sources in the earth’s crust. While a few reviews have summarized and discussed the advances in both cathode and anode materials, a comprehensive and profound review focusing on the material design strategies that are both representative of and peculiar to the performance improvement of rechargeable Mg-based batteries is rare. In this mini-review, all nine of the material design strategies and approaches to improve Mg-ion storage properties of cathode materials have been comprehensively examined from both internal and external aspects. Material design concepts are especially highlighted, focusing on designing “soft” anion-based materials, intercalating solvated or complex ions, expanding the interlayer of layered cathode materials, doping heteroatoms into crystal lattice, size tailoring, designing metastable-phase materials, and developing organic materials. To achieve a better anode, strategies based on the artificial interlayer design, efficient electrolyte screening, and alternative anodes exploration are also accumulated and analyzed. The strategy advances toward Mg–S and Mg–Se batteries are summarized. The advantages and disadvantages of all-collected material design strategies and approaches are critically discussed from practical application perspectives. This mini-review is expected to provide a clear research clue on how to rationally improve the reliability and feasibility of rechargeable Mg-based batteries and give some insights for the future research of Mg-based batteries as well as other multivalent-ion battery chemistries.
