Front Cover: Probing the Properties of Locally Formed Solid Electrolyte Interphases on Hard Carbon Anodes (ChemElectroChem 10/2025)

The image shows the formation and analysis of a locally generated solid electrolyte interphase (SEI) spot on a hard carbon composite anode using scanning electrochemical cell microscopy in either carbonate‐ or ether‐based electrolyte. Post‐mortem atomic force microscopy ‐ secondary ion mass spectrometry (SIMS) was used to identify the chemical composition of the SEI by depth profiling. Further details can be found in the Research Article by Christine Kranz and co‐workers (DOI: 10.1002/celc.202400707 ).
