Quantification of lithium in LIB electrodes with glow discharge optical emission spectroscopy (GD-OES)

Surface Film Formation and Dissolution in Si/C Anodes of Li-Ion Batteries: A Glow Discharge Optical Emission Spectroscopy Depth Profiling Study

“…Others used approaches different from direct calibration of GD-OES, such as elemental ratios and comparison to ICP results. ,, A direct GD-OES calibration was recently done by Ghanbari et al for Li which was in good agreement with ICP-OES results . However, for Si quantification via ICP measurements, hazardous conditions (HF) are necessary to dissolve Si.…”

Deciphering the lithium ion movement in lithium ion batteries: determination of the isotopic abundances of 6Li and 7Li

“…Moreover, it is possible to detect a wide range of concentrations simultaneously, as well as a semi-quantitative evaluation without the need for standardized matrices. [43][44][45] Nonetheless, the loss of lithium was already reported extensively in the literature, while the origin is still not fully claried. Here, the use of isotope-labeled materials would help to better understand these losses and tailor future LIB for their needed desires.…”

Depth profiling of graphite electrode in lithium ion battery using glow discharge optical emission spectroscopy with small quantities of hydrogen or oxygen addition to argon

“…Recent reports have also described that rf-GD-OES is applicable for the analysis of carbon-based negative electrodes. 6,7 The hard carbon electrodes (30 mm active layer) were measured up to the Cu current collector. However, the measurements took a long time, 5000-8000 s, in contrast with 2000-3000 s for positive electrodes (30 mm active layer) because of a low sputtering yield of carbon (0.12 atoms per ion compared to 1.0 for Fe, at 400 eV Ar ions 8 ).…”
