Understanding the Configurational Entropy Evolution in Metal-Phosphorus Solid Solution for Highly Reversible Li-Ion Batteries.

ABSTRACT: The high-entropy materials (HEM) have attracted increasing attention in catalysis and energy storage due to their large configurational entropy and multiunique properties. However, it is failed in alloying-type anode due to their Li-inactive transition-metal compositions. Herein, inspired by high-entropy concept, the Li-active elements instead of transition-metal ones are introduced for metal-phosphorus synthesis. Interestingly, a new Zn_x Ge_y Cu_z Si_w P₂ solid solution is successfully synthesized as proof of concept, which is first verified to cubic system in F-43m. More specially, such Zn_x Ge_y Cu_z Si_w P₂ possesses wide-range tunable region from 9911 to 4466, in which the Zn_0.5
