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 in 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.

In our webinar, Dr. Shibabrata Basak from Forschungszentrum Jülich will show how the DENSsolutions Stream system enables the control of critical parameters such as liquid flow, creating a stable and reproducible environment ideal for investigating electrochemical processes of interest. Moreover, he will demonstrate how the system enables the acquisition of structural and chemical information, revealing details about electrochemical processes. During this webinar, Dr. Basak will also explore how the use of image processing allows for the extraction of detailed information from experimental datasets, representing the first steps towards quantification.

This advance in LPTEM provides the pathway to develop new and more efficient energy technologies that can help address the global energy challenges that we face today.
