2005年12月1日 · Based on the spectroscopy data, we propose a reaction mechanism that features reductive cleavage of a PEO molecule by lithium atoms, which yields not only lithium alkoxides (ROLi) but also ...

基于聚氧化乙烯（PEO）的 聚合物电解质 （PEs）由于其高离子导、价格低廉等优势，已被认为是固态电池的最佳固态电解质之一。 然而，如何制备出超薄和对高电压稳定的PEs仍然是一个挑战。 作者采用涂布的方法制备出微米级的基于聚氧化乙烯（PEO）、聚甲基丙烯酸甲酯（PMMA）和聚偏氟乙烯-六氟丙烯共聚物薄膜，然后使用 丁二腈 （SN）和 氟代碳酸乙烯酯 （FEC）作为增塑剂合成厚度为8.1微米的共混聚合物凝胶电解质（BPE）。 研究表明该共混聚合物凝胶电解质 …

2006年12月18日 · XPS measurements of poly (ethylene oxide) recorded with a SSX-100 spectrometer in standardized experimental conditions are presented: survey scan, high resolution core level spectra as well as the energy loss regions of carbon and oxygen peaks are analyzed.

This study demonstrates that the combination of poly ethylene oxide (PEO) with two conducting polymers, polypyrrole (PPy) and poly (3,4-ethylenedioxythiophene) PEDOT:polystyrene sulfonate (PSS),...

Solid-state polymer electrolytes (SPEs) are proposed as promising candidates for application in sodium batteries to replace the organic liquid electrolytes for enhanced safety. In this study, we...

2021年9月15日 · By using the PEO method, the formation of TiO 2 /P was obtained being characterized by XPS. Results showed binding energies due to the incorporation of P atoms in the TiO 2 crystalline lattice by two possible ways: (i) incorporating P ion as phosphate [TiO 2 /(PO 4 ) 3− ] where P substitutes a Ti site; (ii) the formation of [TiO 2 /P] where a ...

2024年6月20日 · The cycle life of poly(ethylene oxide) (PEO) batteries containing lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) is hindered by interfacial (electro)chemical electrolyte decomposition, a process traditionally examined via X-ray photoelectron spectroscopy (XPS).

This work comprises studies of solid electrolyte interphase (SEI) formation in SPE-based graphite|Li cells using X-ray photoelectron spectroscopy (XPS). SPEs based on high molecular weight poly(ethylene oxide) (PEO) and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) salt …
