Abstract:
A precursor structure is provided. The precursor structure has the following chemical formula:

·

,
wherein M is a trivalent ion or a pentavalent ion, M′ is a bivalent ion, x=0-1, y=0-1.5, and the precursor structure includes a pyrochlore phase. Since the pyrochlore phase may be transformed into the garnet phase through a lithiation process and the phase transition temperature is lower (e.g., 500-1000° C.), the precursor structure may be co-fired with the cathode material (e.g., lithium cobalt oxide (LiCoO2)) to form a thin lamination structure. That is, the thickness of the solid electrolyte may be effectively reduced, thereby improving the ionic conductivity of the solid electrolyte ion battery.
