The rapidly expanding field of nonaqueous multivalent intercalation batteries offers a promising way to overcome safety, cost, and energy density limitations of state-of-the-art Li-ion battery technology. We present a critical and rigorous analysis of the increasing volume of multivalent battery research, focusing on a wide range of intercalation cathode materials and the mechanisms of multivalent ion insertion and migration within those frameworks. The present analysis covers a wide variety of material chemistries, including chalcogenides, oxides, and polyanions, highlighting merits and challenges of each class of materials as multivalent cathodes. The review underscores the overlap of experiments and theory, ranging from charting the design metrics useful for developing the next generation of MV-cathodes to targeted in-depth studies rationalizing complex experimental results. On the basis of our critical review of the literature, we provide suggestions for future multivalent cathode studies, including a strong emphasis on the unambiguous characterization of the intercalation mechanisms.

多价阴极材料的奥德赛：未解决的问题和未来的挑战

非水多价插层电池领域的迅速发展为克服最新锂离子电池技术的安全性，成本和能量密度限制提供了一种有前途的方法。我们对日益增长的多价电池研究数量进行了严格而严格的分析，重点是广泛的插层阴极材料以及这些框架内多价离子插入和迁移的机制。本分析涵盖了多种材料化学，包括硫族化物，氧化物和聚阴离子，突出了每种材料作为多价阴极的优缺点。该评论强调了实验和理论的重叠，从绘制有助于开发下一代MV阴极的设计指标到合理化复杂实验结果的有针对性的深入研究。在我们对文献进行批判性审查的基础上，我们为未来的多价阴极研究提供了建议，包括着重强调嵌入机制的明确表征。
