“…In addition, SSEs need to remain electrochemically stable toward the lithium metal and cathode; otherwise, this will result in a loss of battery capacity and life . Based on the differences in chemical composition, SSEs are categorized as inorganic solid electrolytes (ISEs) and solid polymer electrolytes (SPEs). , Among ISEs, the garnet-type electrolyte Li 7 La 3 Zr 2 O 12 (LLZO) has been widely investigated due to its high ionic conductivity of ∼10 –4 S cm –1 at room temperature and high stability against lithium metal anodes . The crystal structure of cubic LLZO consists of two parts, the ZrO 6 octahedron connected to the LaO 8 dodecahedron to form a three-dimensional (3D) framework structure, with Li1 and Li2 atoms occupying the tetrahedral interstitials (LiO 4 , 24 d) and the distorted octahedral interstitials (LiO 6 , 96 h), respectively. , The LiO 4 and LiO 6 share the face, which provides the short lithium transport pathway.…”
