Elemental Two‐Dimensional Materials for Li/Na‐Ion Battery Anode Applications

Abstract

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.

Two-Dimensional Iron Phosphorus Trisulfide as a High-Capacity Cathode for Lithium Primary Battery

“…Other materials for LPBs mainly include copper vanadate (CuV 2 O 6 ) [ 12 ], silver vanadium oxide (Ag 2 V 4 O 11 ) [ 13 ], aluminum fluoride (Li/AlF 3 ) [ 2 ], and manganese dioxide (Li/MnO 2 ) [ 14 ] with layered structures. However, unfortunately, the multistep reductions that occur during the insertion/intercalation of lithium in these materials results in their low specific capacity [ 15 ]. Two-dimensional metal chalcogenides (2DMCs) with carbon are a well-studied system for lithium batteries [ 16 ].…”
