报告摘要

Understanding in detail the nanoscale dynamics of electrochemical interfaces is crucial for the rational design of electrochemical energy devices, such as lithium (Li) batteries and Li-mediated nitrogen reduction (LiNR), but has remains tremendously challenging. Advanced spectroscopy and microscopy are powerful for unveiling the interfacial dynamics and to deepen their mechanistic understanding. For instance, cryogenic electron microscopy (FIB/SEM & cryo-TEM and tomography) has emerged as a useful tool for ex situ visualizing the native states of sensitive lithium metal and interphases on the nanoscale. Operando & in situ X-ray & Neutron spectroscopy and microscopy (e.g., XPS, XRS, XCT and NDP) are particularly useful for monitoring the dynamic evolution of chemistry and morphology of Li metal electrodes and interfaces during operation. Here I will present mechanistic understandings of Li deposition and solid-electrolyte-interphase (SEI) formation in lithium metal batteries and my recent efforts on LiNR.
