Solid Electrolytes Based on NASICON-Structured Phosphates for Lithium Metal Batteries

All-solid-state lithium batteries are a promising alternative to commercially available lithium-ion due their ability achieve high energy density, safety, and compactness. Electrolytes key components of all-solid-state batteries, as they crucial in determining the batteries’ efficiency. Herein, structure LiM2(PO4)3 (M = Ti, Ge, Zr) migration mechanisms introduced well different synthetic routes doping (co-doping), influence on conductivity is discussed. The effective methods reducing electrolyte/electrode interface resistance improving ion-conducting properties summarized. In addition, polymer/NASICON composites considered. challenges prospects practical applications NASICON-type phosphates electrolytes for
