Abstract:
Provided are an oxide including a compound represented by Formula 1, a method of pre paring the same, a solid electrolyte including the oxide, and an electrochemical device including the oxide:
LiaTa2−yAyP1−xMxO8−zXz Formula 1
wherein, in Formula 1, M is an element having an oxidation number of +3,
A is an element having an oxidation number of +4, +5, or +6, or a combination thereof,
when A is an element having an oxidation number of +4, a is 1+y+2x−z,
when A is an element having an oxidation number of +5, a is 1+2x−z,
when A is an element having an oxidation number of +6, a is 1−y+2x−z,
X is a halogen atom or a pseudohalogen, and
0≤y
