2024年5月24日 · In this work, we use ATR-FTIR to characterize a series of LiF bulk and thin-film reference samples to determine a baseline of LiF structural characteristics compatible with SINS measurements. Then, the LiF structure and distribution were evaluated with SINS on the nanometer scale in the SEI layer on a Cu- and Si-based model Li-ion electrodes in ...

Evidence for a linear dimer Li,F, has been obtained by extending the spectral measurements for matrix isolated lithium fluoride into the far infrared region. The \'apors from solid 6LiF 7LiF and "LiF/'LiF mixtures were deposited in argon matrices at liquid hydrogen temperatures.

2024年12月26日 · This study aims to explore the effectiveness of three spectroscopic methods, Near-Infrared Spectroscopy (NIRS), Fourier Transform InfraRed (FTIR) spectroscopy, and Laser-Induced Fluorescence (LIF) spectroscopy, in conjunction with Principal Component Analysis (PCA) for distinguishing factors related to different extraction techniques and ...

2021年12月1日 · Fourier transform infrared spectroscopy (FTIR) analysis was carried out to investigate the change of chemical bonding of PLLE with LiNO 3 addition. The complete FTIR spectra from 4000 to 400 cm –1 (Fig. 1 d) shows that

2023年7月30日 · The paper presents a study of the crystal structure of anhydrous halides LiF, LiCl and LiBr using density functional theory. Models composed of 125 atoms were used for this study. The theoretical values of the lattice parameters and the distribution of charges in the crystals were determined.

LIF spectra were measured using a tunable optical parametric oscillator (OPO) laser source with UV-doubling option covering the 210 to 750 nm (OPOTEK Vibrant UV) spectral range. The pulse energy...

2024年5月24日 · In this work, we use ATR-FTIR to characterize a series of LiF bulk and thin-film reference samples to determine a baseline of LiF structural characteristics compatible with SINS measurements.

Ultrabroadband near-field synchrotron infrared nanospectroscopy (SINS) enables such detection and mapping of LiF in SEI layers in the far-infrared region down to ca. 322 cm –1 with a nanoscale spatial resolution of ca. 20 nm.

2024年5月2日 · XPS and FTIR spectra confirmed that NBSF can form an SEI layer with high-quality and abundant LiF and Li 3 N on the lithium surface by reaction with LiOH to facilitate uniform deposition of lithium ions and inhibit dendrite growth. Meanwhile, the phenyl-based SEI component can stabilize the lithium anodes.
