Cover Feature: Analysis of Carbonate Decomposition During Solid Electrolyte Interphase Formation in Isotope‐Labeled Lithium Ion Battery Electrolytes: Extending the Knowledge about Electrolyte Soluble Species (Batteries & Supercaps 11/2020)

The Cover Feature illustrates the analysis of isotope labeled (red) electrolytes to define linear and cyclic carbonate origins of lithium-ion battery electrolyte decomposition species. Based on enabled carbon atom tracing, possible reaction pathways resulting in observed species are addressed with respect to their consistency with measured labeling. More information, especially on reductive EC decomposition during SEI formation, can be found in the Article by C. Peschel, S. Nowak and co-workers.
