dc.description.abstract | Li-ion conductors are pivotal materials for all-solid-state Li batteries requiring high energy densities and operational safety. PS4-based thio-phosphate materials have been intensively investigated as solid electrolytes; however, studies on more stable P2S6-based materials are scarce. We herein report on the application of Zn-substituted Li4P2S6, Li4−2xZnxP2S6, as a Li-ion conductor. Owing to the slightly smaller ionic radius of Zn2+ than Li+, the unit cell volume decreases gradually upon Zn substitution without introducing significant structural changes. However, the ionic conductivity of the substitution phase was improved by 104 times (3.8 × 10−6 S cm−1) at x = 0.75 compared to unsubstituted Li4P2S6, which was achieved by generating deficiency on the Li sites via substitution. Such Li-ion deficient site enables Li ions to hop from one site to another in the crystal structure. The 3D diffusion pathway analysis using bond-valence-landscape-energy calculations suggests that the Li diffusion pathways are mostly two-dimensional in the ab plane in this structure. This study shows that an appropriate Li defect concentration within a given structure is critical to improving ionic conductivity. © 2023 Elsevier Inc. | - |
