Invited for this month's cover picture is the work of Prof. Groß’ and Prof. Behm's groups at the Helmholtz Institute Ulm (HIU) Electrochemical Energy Storage and Ulm University. The cover picture shows the model study on the chemical reactions of the ionic liquid BMP‐TFSI with Li atoms. The combined study of XPS experiments and DFT calculations identified various initial products in the solid‐electrolyte interphase formation.

In detail, the authors employ photoelectron spectroscopy and density functional theory calculations to study the interactions and initial chemical processes between ionic liquids and alkali metal atoms at model electrode surfaces. By combining results from experiment and theory, possible decomposition products that might be critical in the formation of the solid‐electrolyte interphase (SEI) could be identified…” Learn more about the story behind the research featured on the front cover in this issue's Cover Profile.
