"Detection and quantification of lithium for battery applications by using combinations of surface analysis techniques"

The efficiency of Li-ion batteries (LIB) depends on multiple factors. Among them, the mobility of lithium in the solid electrolyte interphase (the so-called SEI), which forms at the surface of negative electrodes, as well as lithium mobility in the active material itself, is being thoroughly studied, though the complex underlying mechanisms are still misunderstood. In such context, the detection of lithium, the characterization of its chemical environment, its quantification, can be challenging. In this talk, studies based on surface analysis techniques, which allowed characterizing lithium in various systems related to LIB applications, will be reported. In addition, novel approaches based on lithium isotopic tracing, that are being developed at the lab, in order to study Li mobility in the SEI or in solid electrolytes (which may be used in future solid-state systems), will also be described.
