Two-Dimensional Black Phosphorus: An Emerging Anode Material for Lithium-Ion Batteries.

Two-dimensional black phosphorus (2D BP), an emerging material, has aroused tremendous interest once discovered. This is due to the fact that it integrates unprecedented properties of other 2D materials, such as tunable bandgap structures, outstanding electrochemical properties, anisotropic mechanical, thermodynamic, and photoelectric properties, making it of great research value in many fields. The emergence of 2D BP has greatly promoted the development of electrochemical energy storage devices, especially lithium-ion batteries.

Synthesis and Electrochemical Behavior of LiFePOF ( = 0.05, 0.1, 0.15, 0.2) by Solvothermal Method.

The F-doped LiFePO₄ material was prepared through a simple solvothermal method by applying hydrofluoric acid as the source of fluorine. The obtained LiFePOF at 0.1 C and 10 C delivered a higher capacity of 153.
