Na is a highly reactive metal and usually only sodium compounds will be observed in XPS spectra. The presence of sodium, especially with the presence of chlorine and an intense hydrocarbon C1s peak, can indicate contamination from manual handling, without the …

Na 是一种高活性金属，通常在 XPS 谱中仅观察到钠化合物。 钠的存在，尤其在存在氯和强碳氢化合物 C1s 峰时，可能表明未戴手套进行手动操作造成了污染。 由于扩散过程，玻璃材料表面可能会表现出钠含量增加。 将玻璃暴露于更高能量的电子（几百 eV 或更高）可能会导致 Na 扩散到主体中或穿过照射区域的表面。 这种柔软的蜡状银色活泼金属于1807年由 Humphry Davy 爵士分离出来，它在很久以前就已在化合物中被识别出来。 在中世纪的欧洲，钠的化合物被用作治疗 …

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,

In this study, the surface composition of Li 4 Ti 5 O 12 electrodes operating in a full sodium−lithium cell is probed by XPS (Figure 8). For the sake of comparison, the pristine electrode Li 4 Ti...

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.

Sodium cobalt oxide (NCO) has been synthesized by a glycine assisted sol-gel combustion method. XRD studies confirm the P2 phase formation of NCO. Na exists in two different environments in the...

A proto-type RT Na-S battery utilizing the optimized electrolyte membrane display a stable open circuit potential of 2.24 V and delivers first discharge capacity as ∼ 677 mA h g⁻¹.

Na is a highly reactive metal and usually only sodium compounds will be observed in XPS spectra. The presence of sodium, especially with the presence of chlorine and an intense hydrocarbon C1s peak can indicate contamination from manual handling, without use of gloves.

Jul 1, 2006 · In the present work, sodium species in the carbon cathodes were studied by X-ray photoelectron spectroscopy (XPS). XPS is a very attractive technique as it allows direct observation of various Na species as well as yielding a measure for …

May 24, 2021 · Here, using cryo-TEM, we investigate the effect of fluoroethylene carbonate (FEC) additive on the solid electrolyte interphase (SEI) structure of a Na-metal electrode.
