abstract = {The development of next-generation electrochemical storage
and conversion devices with betterperformance and longevity
requires understanding the electrochemical processes at the
nanoscale.Our group specializes in utilizing in-situ
electron microscopy in a multimodal approach to unravelthe
dynamic processes governing the performance of energy
materials, such as batteries, solidoxide fuel cells, and
electrolyzers. This presentation highlights our in-situ
electron microscopycapabilities, including gas and liquid
phase experiments, to understand dynamics at
solid-solid,solid-gas, and solid-liquid interfaces.Focusing
on solid-solid interfaces, we examine
lithiation/delithiation dynamics incoated and uncoated
silicon particles. These insights help in understanding
processes inall-solid-state batteries, and developing a
screening method to screen coating materials
andunderstanding their desired architecture.We study
gas-solid interactions to understand catalyst and fuel
electrode behavior underoperational conditions. These
studies provide insights into catalyst exsolution
mechanismsin solid oxide cell electrodes as well as the
behavior of catalysts during CO2 conversionreactions.
Coupled with focused ion beam – scanning electron
microscopy (FIB-SEM)tomography, these findings help us
understand long-term operational impacts on materialsand
provide insights into designing next-generation
electrodes.We are pioneering in-situ liquid phase TEM
studies to understand solid-liquid interactions during
electrochemical processes. We have developed a novel
liquidpurging method that enables high-resolution imaging
and analytical studies within a liquidflow cell. This method
allows for dynamic control of liquid thickness, enabling the
studyof electrochemical processes under realistic
conditions. We are utilizing this to study zincbattery
dynamics to develop better charge-discharge routines and
suitable electrolyteadditives to improve battery
performance.Live processing of in-situ data can help in
interpreting electrochemical phenomena inmuch more depth.
Focused on this, we are developing processing routes to
obtain fastinterpretation of the generated images and
diffraction datasets. We are currently striving tocouple
theoretical predictions into live processing and are working
towards automatinginstruments, allowing for longer duration
experiments, increased throughput, and
improvedreproducibility.},
