2020年10月22日 · High-resolution transmission electron microscopy (HRTEM) and X-ray photoelectron spectroscopy (XPS) were used to study the LiFePO 4 electrode in different states to understand the changes of electrode surface. Moreover, the depth distribution of SEI layer components was investigated by argon-ion sputtering.

2012年8月1日 · Polymer species formed on the surface were monitored using X-ray photoelectron spectroscopy (XPS), energy dispersive X-ray spectroscopy (EDX) and the electrochemical characteristics were studied by means of cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS).

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. These reference pages contain tips and techniques that are designed to help both the novice and advanced XPS user.

2016年6月3日 · The chemical composition and valence state of LiFePO 4 /C material was confirmed by XPS analysis. Figure 2(a) shows the wide range-scanning spectrum, which consists of Li, Fe, P, O and C ...

The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra. Atom% values from surveys are based on sample, as received, and Scofield cross-sections. Atom% values are corrected for IMFP and PE. Peak-fits are guides for practical, real-world applications.

2010年9月28日 · In this work, we have experimentally evidenced the valence electronic structure of LiFePO 4 and of its delithiated compound FePO 4 by X-ray photoelectron spectroscopy (XPS), which allows a visualization of the occupied densities of states (DOS) in the valence band.

2012年1月19日 · In order to get more insight in such mechanisms, the evolution of both electrodes of a LiFePO 4 // graphite cell after 200 cycles at RT and 60°C was followed using X-Ray Photoelectron Spectroscopy (XPS). The results have revealed a lack of reversibility of the Fe 3+ /Fe 2+ redox reaction increasing upon cycling and at high temperature.

PTCLi4-coated LTO powders were observed by SEM and the corresponding EDX mapping as well as micro-Raman and XPS spectroscopic analyses confirmed the efficient surface coverage of the anode...
