Although one of the most mature battery technologies, lithium-ion batteries still have many aspects that have not reached the desired requirements, such as energy density, current density, safety, environmental compatibility, and price. To solve these problems, all-solid-state lithium batteries (ASSLB) based on lithium metal anodes with high energy density and safety have been proposed and become a research hotpot in recent years. Due to the advanced electrochemical properties of 2D materials (2DM), they have been applied to mitigate some of the current problems of ASSLBs, such as high interface impedance and low electrolyte ionic conductivity. In this work, the background and fabrication method of 2DMs are reviewed initially. The improvement strategies of 2DMs are categorized based on their application in the three main components of ASSLBs: The anode, cathode, and electrolyte. Finally, to elucidate the mechanisms of 2DMs in ASSLBs, the role of in situ characterization, synchrotron X-ray techniques, and other advanced characterization are discussed.
尽管锂离子电池是最成熟的电池技术之一，但在能量密度、电流密度、安全性、环境兼容性和价格等诸多方面仍未达到理想要求。为解决这些问题，基于锂金属负极、具有高能量密度和安全性的全固态锂电池（ASSLB）被提出，并成为近年来的研究热点。由于二维材料（2DM）具有先进的电化学性能，它们已被用于缓解全固态锂电池当前存在的一些问题，如高界面阻抗和低电解质离子电导率。在这项工作中，首先综述了二维材料的背景和制备方法。基于二维材料在全固态锂电池三个主要组件（阳极、阴极和电解质）中的应用，对其改进策略进行了分类。最后，为阐明二维材料在全固态锂电池中的作用机制，讨论了原位表征、同步辐射X射线技术和其他先进表征的作用。
