Claim 18:
19. A method of preparing an ion conductor, the method comprising:
providing at least one oxide represented by Formulae 1 to 3 to form a precursor mixture

Li4±xM1−x′M′x′O4   Formula 1

wherein in Formula 1,
0≤x≤1 and 0≤x′≤1 ,
M is Zr, Hf, or a combination thereof,
M′ is Y, Al, Ta, Mg, Zn, or a combination thereof, with the proviso that when M is Zr, then x≠0, and M′ is Ta, or a combination of Y and Ta;

Li4−yM″O4−yA′y   Formula 2

wherein in Formula 2,
0≤y≤1,
M″ is a Group 4 element,
A′ includes at least one halogen;

Li4+4zM′″1−zO4   Formula 3

wherein in Formula 3,
0<z<1,
M″′ is a Group 4 element; and
heat-treating the precursor mixture in the oxidizing atmosphere, a reducing atmosphere, or a combination thereof,
wherein the ion conductor has an ionic conductivity of about 2×10−7 mS/cm or more at about 60° C.
