Rational design of a PC3 monolayer: A high-capacity, rapidly charging anode material for sodium-ion batteries

Abstract

Sodium-ion batteries (SIBs) have received a great deal of attention as an alternative to lithium-ion batteries due to their intrinsic safety and sodium's earth abundance. The major scientific challenge for a competitive sodium-ion battery technology is development of highly efficient anode materials. The stability of carbon materials and high specific capacity of phosphorus materials motivate us to examine carbon–phosphorus solid solutions as anode materials. Here, we rationally designed a puckered honeycomb structure of an ideal anode material, PC
