Title

Understanding the role of Li local structure in garnet-structured Li7La3Zr2O12 solid electrolytes

Abstract

Li-stuffed garnet oxides are promising solid electrolyte materials for application in solid-state Li-ion batteries. Our research team is working on the development and understanding of high-performing solid electrolytes based on doped Li7La3Zr2O12 (LLZO). By heterovalent substitutional doping, Li vacancies can be created in the garnet structure, providing fast lithium conduction paths of contiguous tetrahedral and interstitial octahedral sites with disordered Li occupancies. Given the high influence of local structure on the Li+ conductivity, this proposal aims to understand the effect of various cationic substitutions on the disordered Li sublattice.
