Design Of Black Phosphorous Derivatives With Excellent Stability And Ion-Kinetics For Alkali Metal-Ion Battery

Two-dimensional black phosphorus (2D BP) and its derivatives has recently attracted significant research attention on energy storage devices due to its extremely high electronic conductivity, anisotropic structural advantages and high specific capacity. Through in-depth research, the performance defects of BP-based devices are discovered, which is mainly due to the poor chemical stability of BP. In order to solve the above issues, by integrating the unique properties of foreign materials and the advantages of BP into a single hybrid hetero-structure, a variety of black phosphorus derivatives (BPDs) have been constructed as emerging types of multifunctional materials. With the rapid development of BPDs, a timely review on this topic is in demand to further extend the application of BPDs in alkali metal-ion battery (AMIBs), especially sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs), they are the new generation metal-ion batteries due to the abundance natural reserve and cost-effective merits of Na and K. Here, the design of BPDs with excellent stability/ion-kinetics and the progress of BPDs anodes for AMIBs are systematical reviewed, which are not only crucial for in-depth understanding of electrochemical energy storage mechanism but also to provide further insights and enabling rational design methodologies. Finally, the challenges of BPDs in the development of AMIBs are presented, hoping to provide some inspirations for the design and fabrication of advanced alkali metal energy storage systems.
