Two-dimensional (2D) nanostructure is currently the subject in the fields of new energy storage and devices. During the past years, a broad range of 2D materials represented by graphene have been developed and endow with excellent electrochemical properties. Among them, elemental 2D materials (Xenes) are an emerged material family for Li/Na-ion battery (LIB/SIB) anodes. Compared with other 2D materials and bulk materials, Xenes may exhibit some great superiorities for Li/Na storage, including excellent conductivity, fast ion diffusion and large active sites exposure. In this review, we provide a systematic summary of the recent progress and achievements of Xenes as well as their applications in LIBs/SIBs. The broad categorization of Xenes from group IIIA to VIA has been concisely outlined, and the related details in syntheses, structures and Li/Na-ion storage properties are reviewed. Further, the latest research progress of Xenes in Li/Na ion batteries are summarized, together with mechanism discussions. Finally, the challenges and prospects of Xenes applied to Li/Na ion battery are proposed based on its current developments.
二维（2D）纳米结构目前是新能源存储与器件领域的研究热点。在过去几年中，以石墨烯为代表的多种二维材料得到了发展，并具有优异的电化学性能。其中，单质二维材料（Xenes）是用于锂/钠离子电池（LIB/SIB）负极的新兴材料家族。与其他二维材料和块状材料相比，Xenes在锂/钠存储方面可能展现出一些巨大优势，包括优异的导电性、快速的离子扩散以及大量活性位点的暴露。在本综述中，我们系统总结了Xenes的最新进展和成果及其在LIBs/SIBs中的应用。简要概述了从IIIA族到VIA族Xenes的广泛分类，并对其合成、结构和锂/钠离子存储性能的相关细节进行了综述。此外，总结了Xenes在锂/钠离子电池中的最新研究进展，并进行了机理讨论。最后，基于其当前的发展情况，提出了Xenes应用于锂/钠离子电池面临的挑战和前景。
