Title: High conductivity NASICON electrolyte for room temperature solid-state sodium ion batteries

Abstract

Solid electrolytes compositions, methods of making the solid electrolytes, and methods of using the solid electrolytes in batteries and other electrochemical technologies are disclosed. The method of producing a solid electrolyte comprises (a) ball milling Na2CO3, SiO2, NH4H2PO4, a zirconium source, and a dopant to produce a ball milled powder; (b) calcining the ball milled powder to produce a calcined powder; and (c) sintering the calcined powder to produce a solid electrolyte. The zirconium source for the solid electrolyte may be ZrO2. The dopant for the solid electrolyte may be AI2O3, Fe2O3, Sb2O3, Yb2O3, or Dy2O3.
