First principles theoretical of designing Sandwich-like Metallic BP4 Monolayer as Anode for Alkali Metal-ion Batteries

Phosphorene has been widely used as anode material for batteries. However, the huge volume change during charging and discharging process, the semiconductor properties, and the high open circuit voltage limit its application. Based on this, by introducing the electron-deficient boron atoms into blue phosphorene, we proposed a P-rich sandwich-like BP
