Abstract: In recent years, in-situ liquid-phase transmission electron microscopy (LPTEM) has emerged as a powerful technique for investigating the dynamic electrochemical processes that occur in electrochemical storage and conversion systems. However, to obtain accurate and reliable results, it is essential that the chemical environment within the TEM can be precisely controlled in a reproducible manner so that the nucleation and growth of lithium or zinc or the conversion of CO2 at the electrocatalysts can be studied under realistic conditions. Additionally, the system should enable obtaining high-quality imaging and analytical information to gain valuable insights into the underlying mechanisms that govern these complex systems.Smart micro electrical mechanical systems (MEMS) and holder designs have enabled us to control liquid flow and thickness, allowing us to create a stable and reproducible environment that is ideal for investigating the electrochemical processes of interest. This has also enabled us to obtain structural, and chemical information that reveals details about the electrochemical processes using 4DSTEM, EDX, EELS. Furthermore, the use of image processing has allowed us to extract detailed information from the experimental data sets, taking the first steps toward quantification. This advance in LPTEM provides the pathway to developing new and more efficient energy technologies that can help to address the global energy challenges.
