2024年1月1日 · Compared with water and ethanol, the surface of the washed sample was smooth by H 3 BO 3, which could significantly improve the charge transfer at the interface between the electrode and the electrolyte. Importantly, boric acid did not cause changes in the valence state of the transition metal on the surface [21].

2021年1月15日 · H 3 BO 3 -washed NCM811 exhibits excellent storage performance. LiNi 0.8 Co 0.1 Mn 0.1 O 2 (NCM811) is a very promising Ni-rich layered cathode material for Li-ion batteries due to its low cost and high discharge capacity. However, the residual lithium deteriorates its electrochemical and storage performances, which hinders its application.

2022年8月1日 · This work successfully synthesizes boron-contained coatings through a simple dry mixing and a low-temperature heating treatment. Transmission electron microscopy (TEM) and X-ray photoelectron spectrum (XPS) prove that the boron-contained compounds are successfully introduced to the surface of the matrix.

Both TEM and XPS measurements demonstrate that a thin layer of amorphous B2O3 is successfully coated on the surface of 1B2O3@NCM111 particles. XRD, SEM and TEM testing results show that the morphology and lattice structure present little change after coating.

2023年6月7日 · Using the galvanostatic intermittent titration technique, electrochemical impedance spectroscopy (EIS), and inductively coupled plasma-optical emission spectroscopy (ICP-OES), we reveal the mechanism by which the electrochemical properties are improved upon H3BO3 modification.

Transmission electron microscopy (TEM) and X-ray photoelectron spectrum (XPS) prove that the boron-contained compounds are successfully introduced to the surface of the matrix. The electrochemical performance of the boron-coated sample presents great improvement with a capacity loss of less than 2% and a distinctly suppressed electrochemical ...

为了证明其潜力，这项工作研究了 FeCrAl 合金在360 °C 和 18.5 MPa 的H 3 BO 3 - 和 LiOH- 水中的腐蚀行为500 小时。 采用 XPS、XRD、SEM、拉曼和 AFM 分析识别氧化膜，并讨论了 FeCrAl 的早期腐蚀机制。 在 FeCrAl 表面发现了双相氧化膜。 内层为Fe-Cr-Al尖晶石，外层晶体以Fe 2 O 3 为主，辅以Fe 3 O 4 、FeCr 2 O 4 、NiFe 2 O 4 和Li 2 Fe 3 O 4。 与 FeCrAl 类似，Zircaloy-4 的重量变化可以忽略不计。 但其表面腐蚀较严重，形成的氧化物主要是ZrO 2 和Zr 3 O 1-X。 …

(1) XPS technique served as a powerful tool for detecting the presence of small amount of H3BO3 or B2O3 in the BPO4 sample. (2) The XPS B 1s spectrum of the BPO4 sample was able to be deconvoluted into two peaks; one with higher binding energy was assigned to …

The Basic XPS Information Section provides fundamental XPS spectra, BE values, FWHM values, overlays of key spectra, BE tables, 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,

Flake boron nitride (BN) in large yield was successfully synthesized at low temperature from the combustion synthesized precursor. The precursor was prepared by a low-temperature (350 °C)...
