This Special Issue will highlight advancements for in situ and operando characterization techniques for energy materials, focusing on methods and protocols that provide critical insights into their behavior. Submit your manuscript by October 31, 2025.

Three transparent battery cells filled with a green liquid, featuring spiral designs and a high-tech digital display motif.

Energy materials in functional devices often operate under non-equilibrium conditions, where their structures and properties deviate from equilibrium states. Capturing their real-time behavior under operating conditions or with appropriate temporal resolution is crucial for understanding their performance and failure mechanisms.

A new Special Issue from Chemistry of Materials will focus on this exciting topic, highlighting cutting-edge approaches that enable such insights, driving progress in energy materials research and application.

Topics include, but are not limited to:

  • Spectroscopic methods e.g., operando optical, Raman, X-ray/neutron, XPS, X-ray tomography, Mössbauer spectroscopy, EPR, NMR, MRI, and EM as well as multimodal characterization with integration of complementary techniques.
  • Applications include solid-state batteries and hybrid systems, fuel cells, electrolyzers, solar cells, thermoelectrics and hydrogen storage technologies.

Submit your manuscript by October 31, 2025.
