LIBS and LDI-MS as Complimentary Techniques for Interphase Characterization in Lithium-Ion Batteries

Balke presents laser-induced breakdown spectroscopy (LIBS) as a valuable method to assess the elemental composition of the solid electrolyte interphase (SEI) that forms on the lithium-ion battery anode surface upon charging of the battery. Two detection systems, continuous metal oxide semiconductor (CMOS) and intensified charged-coupled device (ICCD), are compared towards its suitability for the analysis of C, H, O, P, Li, and F in the SEI.

By combining individual spot measurements in the range of 25 to 150 µm of the electrode, images are created that may lead to conclusions about the spatially resolved distribution of organic and inorganic SEI constituents, as well as species that accumulate in the interphase.
