Two-Dimensional Materials for Li-Ion Batteries and Catalysts

Two-dimensional (2D) materials have shown great potential in advanced Li-ion batteries and catalysis. Due to the lamellar feature and unique physical/chemical properties, 2D materials and their structures have been widely used in fabricating electrochemical electrodes or electrolytes for improving performance, stability, safety, manufacturing cost, etc. However, the current progress is still far from ideal. Synthesis of 2D materials is challenged by cost, yield, functionalization and even stability of 2D materials themselves. Also structural control and the corresponding contribution to electrochemical reactions should be well studied. Introducing 2D sheets often increases electrochemical reaction sites; however, their 2D nature may block ion migration and also generates excessive SEI layer consuming electrolyte. Moreover, 2D materials trigger complicated electrochemical ion-transport behavior, especially for ion-transport in the caused interlayer-confined channels. Hence, despite the bright future for high-performance Li-ion battery, further studies are needed to address the above issues of 2D materials.

This research topic aims to present latest advances of 2D materials in advanced Li-ion batteries and catalysts, including structural control, synthesis strategies, ion-transport kinetics, improved ion-storage and catalytic mechanism.
