| Outline of Final Research Achievements |
Na3Zr2Si2PO12 solid electrolyte is the chemically-stable against Na metal. However, cell voltage become unstable when the Na metal is used as anode, if the porosity of the electrolyte is high. The reactivity of Na3Zr2Si2PO12 with La0.6Sr0.4Co0.2Fe0.8O3 air electrode was studied. When the calcination temperature is higher than 800℃, the reaction is occurred. In order to make ideal interface between electrode and electrolyte, all-solid-state sodium battery with a single material was studied by using Na2.6V1.6Zr0.4(PO4)3. The Pt/Na2.6V1.6Zr0.4(PO4)3/Pt cell showed very low interfacial resistance at room temperature.
