| Research Abstract |
In this study, we aimed to develop the novel divalent cation conducting solid electrolytes with three dimensional network structure, and we have demonstrated that the NASICON type (MgxHf1-x)4/(4-2x)Nb(PO4)3 and (Sr0.05Hf0.95)4/3.9(Nb1-yWy)5/(5+y)(PO4)3 solids showed the Mg2+ and Sr2+ cation conduction. Furthermore, the (Mg0.1Hf0.9)4/3.8Nb(PO4)3 solid was revealed to have the highest Mg2+ conductivity below 400 oC.
