Journal ArticleDOI
Study of lithium glassy solid electrolyte/electrode interface by impedance analysis
TL;DR: In this article, cells of Li ion conducting glassy electrolyte Li 2SO4-Li 2O-B2O3 with different combinations of electrodes (stainless steel blocking electrode, lithium non-blocking electrode and TiS2 electrode) have been prepared.
Journal ArticleDOI
Conductivite ionique du lithium dans les solutions solides de structure boracite Li4+xB7O12+x/2X (X = Cl, Br) (0 ⩽ x ⩽ 1)
TL;DR: In this article, the evolution of electrical properties as a function of composition has been discussed in terms of structure and chemical bonding in Li4B7O12X-Li2O systems at 750°C.
Journal ArticleDOI
XPS analysis of the lithium intercalation in amorphous tungsten oxysulfide thin films
TL;DR: Amorphous thin films of tungsten oxysulfide have been prepared by radio frequency (RF) magnetron sputtering and the composition of thin films is varied by changing the pressure of the reactive gas (O2) and discharge gas (Ar+O2), in the sputtering chamber as discussed by the authors.
Journal ArticleDOI
X-ray photoelectron spectroscopy: A powerful tool for a better characterization of thin film materials
TL;DR: X-ray photoelectron spectroscopy (XPS) is one of the most powerful tools to characterize thin films materials as mentioned in this paper, and two main kinds of information can be obtained from XPS analysis: the oxidation states and the determination of atomic environments.
Journal ArticleDOI
Surface film morphology (AFM) and chemical features (XPS) of cycled V2O5 thin films in lithium microbatteries
Benoit Fleutot,Hervé Martinez,Brigitte Pecquenard,Jean-Bernard Ledeuil,Alain Levasseur,Danielle Gonbeau +5 more
TL;DR: In this article, the surface layer between the positive electrode and the liquid electrolyte has been characterized and the chemical and topographic changes of this interfacial layer at various stages of cycling are discussed in correlation with the evolution of the discharge capacity over cycles.
