Enhancing ionic conductivity and interfacial stability of argyrodite electrolyte by La/Nd doping toward long-cycle all-solid-state batteries.
Sulfide solid-state electrolytes are promising for all-solid-state lithium batteries but suffer from limited interfacial stability against lithium metal. In this work, trace La3+ and Nd3+ were introduced into Li6PS5Cl (LPSC) to improve both ionic transport and interfacial compatibility. At the optimized doping level of...
