2018年8月13日 · We apply this approach to XPS data sets acquired from six battery-relevant inorganic phases including lithium metal (Li 0), lithium oxide (Li 2 O), lithium peroxide (Li 2 O 2), lithium hydroxide (LiOH), lithium carbonate (Li 2 CO 3), and lithium nitride (Li 3 N).

2018年9月1日 · Here, we investigated effects of inserting a gold thin film to the Li/Li 3 PS 4 interface on the structure of the electrolyte and morphology change of Li metal. XPS analysis revealed that Li 3 PS 4 electrolytes in the vicinity of Li metal were partially reduced regardless of the insertion of the Au thin film.

2021年1月19日 · Against this background, we systematically characterized various lithium samples with X-ray photoelectron spectroscopy (XPS), time-of-flight secondary-ion mass spectrometry (ToF-SIMS), and complementary energy-dispersive X-ray spectroscopy (EDX), resulting in a complete three-dimensional chemical picture of the surface passivation layer.

2025年1月27日 · The solid electrolyte interphase (SEI) is considered to be the key to the performance of lithium metal batteries (LMBs). The analysis of the SEI and cathode electrolyte interphase (CEI) composition (especially F 1s spectra) by X-ray photoelectron spectroscopy (XPS) has become a consensus among researchers.

2024年5月15日 · Quasi-in-situ XPS characterization proved the LiF modification layer can prevent the interface side reactions and inhibit the growth of lithium dendrites, and the Au modification layer can reduce interface impedance and improve interface contact.

4 天之前 · Li-deficient materials are thus excluded from battery design, and the battery fails when active Li ions are consumed 3. Our study breaks this limit by means of a cell-level Li supply strategy.

2019年2月1日 · This work clearly demonstrates the use of XPS in the analysis of SEI layers which play a crucial role in failures of lithium ion batteries in the battery industry. The long standing issue of lithium corrosion and dendrite growth on Li anodes was addressed and ex-situ XPS analysis played a crucial role in developing a modification strategy for ...

2018年8月13日 · We apply this approach to XPS data sets acquired from six battery relevant inorganic phases including lithium metal (Li0), lithium oxide (Li2O), lithium peroxide (Li2O2), lithium...

facilitate accurate phase identification of battery-relevant phases (and electronically insulating phases in general), we propose a straightforward approach for removing charging effects from XPS data sets. We apply this approach to XPS data sets acquired from six battery-relevant inorganic phases including lithium metal (Li
