Abstract To reduce the ecological footprint and to increase lifetime of lithium‐ion batteries (LIBs), it is necessary understand aging phenomena inside cells during cycling. In this study, positive effect external pressure through bracing on investigated for automotive battery with more than 7000 cycles. After cycling, aged are studied by using post‐mortem analysis. It shown that does not affect anode cathode in same manner. A lack results lithium plating due contact losses anode. Such a...
Abstract The generation of hydrogen as a chemical energy storage for power via fuel cells or the synthesis fuels has attained strong interest in recent years. By way example this is realized using electrolysis water with help excess electricity wind plants. However low temperature grade waste heat it could be found many industrial and household applications, there another source usable purpose. In first pragmatic experimentation we investigated pyroelectric effect ferroelectric BaTiO 3...
Abstract. The operation principle of a commercially available solid electrolyte sensor was modified with respect to applications in flowing gaseous mixtures containing H2 and O2. For this purpose the generally applied coulometric or potentiometric mode replaced by cyclic voltammetry. By varying temperature, electrode area potential scan rate, conditions for characteristic peak formation every gas component were determined. While hydrogen oxidation peaks arise at rates up 100 mV s−1, oxygen...
Abstract The time‐resolved oxygen exchange rate of strontium titanate (SrTiO 3 ) single crystals is studied by means solid electrolyte coulometry (OSEC) and compared to model calculations. Experiments are performed on pure, ion implanted (Ni, Ag, O N ions) partially covered with silver layer. In this work, a theoretical used, which based defect chemistry under equilibrium conditions. It applied as fit in order determine the effective constants activation energy reaction crystal surface. OSEC...
Spray-assisted layer-by-layer assembly is applied to the fabrication of functional thin film composites based on colloidal semiconductor nanocrystals (see picture). The technique capable handling various material combinations, yielding varying architectures. Light-emitting devices, including those all-inorganic design, are generated in order demonstrate potential applicability and versatility this approach. Detailed facts importance specialist readers published as ”Supporting Information”....

Coulometric solid electrolyte sensors based on stabilized zirconia were characterized with respect to the electronic conductivity of and their electrochemical activity oxygen, hydrogen hydrocarbon conversion.The temperature dependency as well elevated noise coulometric cell at working restrict limit detection titration.The article contains investigations parameters influencing that approaches decrease it ppb-range.
To achieve solid electrolyte materials for electrochemical energy storage devices with very high oxygen ion conductivity, composites of gadolinium-doped ceria (GDC) and magnesia (MgO) are developed in this study. Three different preparation methods used to prepare nanoparticles from these two components. According the characterization results, self-propagating high-temperature synthesis is best suited both nanometer-sized GDC powder as MgO insulator. The structures prepared powders have been...
ZusammenfassungFlüchtige Fettsäuren (engl.volatile fatty acids, VFA) wie Essig-, Propion-, Butter-und Valeriansäure sind wichtige Inhaltsstoffe für die Beurteilung der Stabilität von Biogasprozessen.Insbesondere bei Verarbeitung organischer Abfälle unterschiedlicher Herkunft Speiseresten zu Biogas ist zeitnahe Überwachung dieser Zwischenprodukte Prozesssicherheit entscheidend.Eine weitere Motivation das Online-Monitoring VFA ergibt sich aus Zielstellung, Biogasprozesse so flexibilisieren,...
Coulometrische Festelektrolytsensoren werden in zunehmendem Maß für verschiedene Applikationen, z.B. die Sauerstoffmessung und Forschung an keramischen Materialien eingesetzt.Einer ihrer wesentlichen Vorteile betrifft ihre relativ genaue Signalabhängigkeit vom Faradayschen Gesetz, einen kalibrierfreien Betrieb über langen Zeitraum ermöglicht.Der Einsatz dieser Sensoren zur Messung von Spurenkonzentrationen im ppm-und ppb-Bereich offenbart Abweichungen durch elektronische Leitfähigkeit des...
