Solid polymer electrolyte films based on PMMA were prepared in different NaClO4 salt concentrations by solution cast technique. The features of complexion of these electrolytes were studied by X-ray diffraction (XRD). Film morphology was examined by Scanning Electron Microscopy (SEM). The electrical conductivity of pure and NaClO4 doped polymer electrolyte films was studied in the temperature r...
The optimization of interfacial charge transfer is crucial to the design of dye-sensitized solar cells. In this paper we address the dynamics of the charge separation and recombination in liquid-electrolyte and solid-state cells employing a series of amphiphilic ruthenium dyes with varying hydrocarbon chain lengths, acting as an insulating barrier for electron-hole recombination. Dynamics of el...
Nitrogen is often used as an inert background atmosphere in solid state studies of electrode and reaction kinetics, of solid state studies of transport phenomena, and in applications e.g. solid oxide fuel cells (SOFC), sensors and membranes. Thus, chemical and electrochemical reactions of oxides related to or with dinitrogen are not supposed and in general not considered. We demonstrate by a st...
We report a methodology for a direct investigation of the solid/liquid interface using high pressure x-ray photoelectron spectroscopy (HPXPS). The technique was demonstrated with an electrochemical system represented by a Li-ion battery using a silicon electrode and a liquid electrolyte of LiClO4 in propylene carbonate (PC) cycled versus metallic lithium. For the first time the presence of a li...
Combining solid electrolytes (SE) and liquid (LE) may resolve interparticle contact issues in solid-state batteries. New challenges arise due SLEI, which needs to be better understood minimize its effects at the cell-level.
*Correspondence: Michael Stoukides, Department of Chemical Engineering, Aristotle University of Thessaloniki, Building E13, Laboratory of Electrochemical Processes, Thessaloniki 54124, Greece e-mail: [email protected] Developed in the early 1900s, the “Haber–Bosch” synthesis is the dominant NH3 synthesis process. Parallel to catalyst optimization, current research efforts are also focused...
