Composite solid electrolyte doped with stannate-based solid electrolyte and preparation method
The invention relates to a stannate-based solid electrolyte-doped composite solid electrolyte and a preparation method thereof, and belongs to the field of sintering aids for solid electrolytes. The composite solid electrolyte doped with the stannate-based solid electrolyte comprises a stannate solid electrolyte and a zirconate solid electrolyte, the molecular formula of the stannate solid electrolyte is ASn < 1-x > B < x > O < 3-alpha >, and the molecular formula of the zirconate solid electrolyte is MZr < 1-y > N < y > O < 3-alpha >. The prepared mixed solid electrolyte proton conductor material is compact in structure, relatively high in relative density and higher in sintering activity, stannate oxide solid electrolyte which is easy to sinter and stable in chemical performance is used as a sintering aid, and an ASnO3 stannate-based solid electrolyte material which is low in sintering temperature, thermal stability and chemical stability is added; and preparing to obtain the mixed solid electrolyte proton conductor material.
