abstract = {Laser desorption/ionization-mass spectrometry (LDI-MS) is
introduced as a complementary technique for the analysis of
interphases formed at electrode|electrolyte interfaces in
lithium ion batteries (LIBs). An understanding of these
interphases is crucial for designing interphase-forming
electrolyte formulations and increasing battery lifetime.
Especially organic species are analyzed more effectively
using LDI-MS than with established methodologies. The
combination with trapped ion mobility spectrometry and
tandem mass spectrometry yields additional structural
information of interphase components. Furthermore, LDI-MS
imaging reveals the lateral distribution of compounds on the
electrode surface. Using the introduced methods, a deeper
understanding of the mechanism of action of the established
solid electrolyte interphase-forming electrolyte additive
3,4-dimethyloxazolidine-2,5-dione (Ala-N-CA) for
silicon/graphite anodes is obtained, and active
electrochemical transformation products are unambiguously
identified. In the future, LDI-MS will help to provide a
deeper understanding of interfacial processes in LIBs by
using it in a multimodal approach with other surface
analysis methods to obtain complementary information.},
