With the progressive increasing of device requirements, rechargeable lithium-ion batteries are facing tremendous challenges in large-scale application due to high price and gradual shortage of lithium sources. In contrast, multivalent ion batteries, such as Al, Mg, and Zn, are promising candidates for the next-generation energy storage systems because of their high volume energy density, safe operation, and abundant reserves. The strong intercalation between multivalent ions and the host materials, however, will cause a lower ion diffusion kinetics and poor discharge capacity. One of the main challenges is to searching a suitable cathode material with a high capacity and good structure stability to overcome above problems. Two-dimensional (2D) layered materials, characteristic of unique structural features, good conductivity, and high electrochemically active surface, have attracted attentions of researchers during the past decade. In this review, we summarize the design approach and synthesis routine of the 2D materials served as a cathode for multivalent ion batteries in detail, including interlayer engineering, 2D heterostructures, pore/hole engineering, and heteroatom doping. Meanwhile, the relationship between configuration design and optimized electrochemical performance is rationally and systematically presented. Besides, the perspectives of sustainable synthesis for cathode materials are proposed for multivalent metal ion chemistry.

多价离子电池二维材料合理设计与合成的最新进展。

随着设备要求的不断提高，可充电锂离子电池由于价格高和锂源逐渐短缺而在大规模应用中面临巨大挑战。相反，由于铝，镁和锌等多价离子电池的体积能量密度高，操作安全且储备丰富，因此有望成为下一代储能系统的候选者。然而，多价离子与主体材料之间的强插入将导致较低的离子扩散动力学和较差的放电容量。主要挑战之一是寻找具有高容量和良好结构稳定性的合适的阴极材料以克服上述问题。二维（2D）分层材料，具有独特的结构特征，良好的导电性，在过去的十年中，高电化学活性表面吸引了研究人员的注意。在这篇综述中，我们详细总结了用作多价离子电池阴极的2D材料的设计方法和合成程序，包括层间工程，2D异质结构，孔/孔工程和杂原子掺杂。同时，合理系统地提出了构型设计与优化的电化学性能之间的关系。此外，提出了用于多价金属离子化学的阴极材料可持续合成的观点。我们详细总结了用作多价离子电池阴极的2D材料的设计方法和合成程序，包括层间工程，2D异质结构，孔/孔工程和杂原子掺杂。同时，合理系统地提出了构型设计与优化的电化学性能之间的关系。此外，提出了用于多价金属离子化学的阴极材料可持续合成的观点。我们详细总结了用作多价离子电池阴极的2D材料的设计方法和合成程序，包括层间工程，2D异质结构，孔/孔工程和杂原子掺杂。同时，合理系统地提出了构型设计与优化的电化学性能之间的关系。此外，提出了用于多价金属离子化学的阴极材料可持续合成的观点。
