Abstract
Electrochemical energy storage devices are provided comprising an anode, a cathode and a solid-state electrolyte adapted for Na-ion conduction between the anode and cathode. The solid-state electrolyte includes, for example, a solid solution of doped NaAlOhaving a composition defined by one of D(NaAlO)in which D is at least one of GeO, SnO, TiO, ZrOand HfO, and D(NaAlO)in which D is PAlO, where 0<x≤0.5. Other solid-state electrolyte compositions are also disclosed.
