You are welcome to attend Lanting Qian's  PhD Defence titled Halide and Sulfide Solid Electrolytes for All-Solid-State Batteries: Structure and Interface Engineering.

Abstract:

All-solid-state batteries (ASSBs) are widely regarded as a promising next-generation energy-storage technology due to their potential to deliver enhanced safety, higher energy density, and improved compatibility with high-voltage electrode materials. This thesis focuses on the design, structural elucidation, and interfacial engineering of halide and sulfide solid electrolytes for high-voltage ASSBs, with particular emphasis on understanding how crystallographic disorder and chemical modification influence lithium-ion transport and interfacial stability. A comprehensive suite of experimental and computational techniques—including synchrotron and neutron diffraction, total scattering and pair distribution function analysis, electron microscopy, X-ray spectroscopies, time-of-flight secondary ion mass spectrometry (ToF-SIMS), electrochemical characterization, and first-principles calculations—is employed to establish robust structure–property–interface relationships.
