Aug 13, 2018 · Accurate identification of chemical phases associated with the electrode and solid–electrolyte interphase (SEI) is critical for understanding and controlling interfacial degradation mechanisms in lithium-containing battery systems.

Sep 6, 2022 · Herein, we present a systematic XPS study of three different Li salts, namely lithium bis (fluorosulfonyl)imide (LiFSI), lithium bis (trifluoromethanesulfonyl)imide (LiTFSI), and lithium hexafluorophosphate (LiPF 6).

X-ray photoelectron spectroscopy (XPS or ESCA) curve fitting procedures, reference materials and useful notes are listed here to provide a starting point for the consistent interpretation of XPS spectra.

Jun 21, 2024 · A comparative and in-depth investigation on the reactivity of various Li-based electrolytes and of the solid electrolyte interface (SEI) formed at graphite electrode is carried out using XPS, chem. simulation test, and differential scanning calorimetry (DSC).

introduced into XPS chemical-state analysis by the coexistence of multiple similar or related phases. For example, the Li 1s core levels associated with numerous distinct Li-containing chemical compounds (including several listed in Table I) common to battery materials lie within 3 eV of each other. Moreover, many SEI phases (including Li 2

Jun 27, 2018 · In this work, operando X-ray photoelectron spectroscopy and real-time in situ Auger electron spectroscopy mapping are developed to probe the formation and evolution of the Li/Li 2 S-P 2 S 5...

Mar 15, 2001 · X-ray photoelectron spectroscopy (XPS) is used to probe the surface layer and element composition of Li-metal electrodes before and after contact with polymer electrolytes containing LiN(SO 2 CF 3) 2 (LiTFSI) or LiBF 4.

The Basic XPS Information Section provides fundamental XPS spectra, BE values, FWHM values, BE tables, overlays of key spectra, histograms and a table of XPS parameters. The Advanced XPS Information Section is a collection of additional spectra, overlays of spectra, peak-fit advice, data collection guidance, material info,
