Two-Dimensional Metal-Containing Nanomaterials for Battery Anode Applications

Secondary batteries, as portable energy storage and supply devices, are becoming an attractive research field that is drawing a lot of attention. Selection of electrode materials plays a crucial role in the battery performances. However, most bulk materials have a lot of limitations when used as battery anodes for lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs). Recently, two-dimensional nanomaterials (2D materials) have been fabricated to address these problems. The high specific surface area of 2D materials can facilitate the electrochemical process during charge-discharge cycles. Therefore, anode materials with expected performances can be designed and be synthesized. In this Review, we summarize the recent development of metal-containing 2D nanomaterials for battery anode applications. The relation between 2D structure and electrochemical performance of materials have been presented. Additionally, existing problems and possible solutions have also been discussed.
