In ancient Goryeo celadon, the effect of the chemical composition and ionic state of Fe on the color was evaluated by Mössbauer spectroscopy and Design of Experiment (DOE) analysis. The ancient celadon pieces excavated from the kiln sites in GangJin and Buan areas were analyzed by Mssbauer spectroscopy, chromaticity, and DOE analysis. The color of celadon was found to be mainly determined by that of glaze since variations of L*, a*, and b* values for the body were much smaller than those for the glaze. As Fe 2+ /Fe3+ in glaze increases, L* value increases, whereas a*/b* value decreases, which is well consistent with the result on the synthetic glaze. As the amount of titanium increases in the glaze, the a* and b* values decrease; on the other hand, the L* value increases, which is well consistent with the result on the synthetic glaze.

View full text Add to dashboard Cite

Moderne Energiespeichertechnologien, einschließlich elektrischer Doppelschichtkondensatoren und wiederaufladbarer Batterien, sind von enormer Bedeutung für Anwendungen in tragbaren Elektronikgeräten, als Elektrizitätsspeicher für Ladestationen von Elektrofahrzeugen und zum Lastausgleich von erneuerbaren Energiequellen wie Sonnenenergie und Windkraft. Der Einsatz von Lithiumbatterien und elektrischen Doppelschichtkondensatoren in diesen Technologien bedarf der wissenschaftlichen Grundlagenforschung. Es gilt, neue Materialien und elektrochemische Reaktionen zu entdecken und ein besseres Verständnis der Prozesse zu erlangen, auf denen die Funktion dieser Energiespeichereinheiten beruht. Dieser Aufsatz fasst einige der aktuellen Fragen im Zusammenhang mit Lithiumbatterien und Doppelschichtkondensatoren zusammen.

Challenges Facing Lithium Batteries and Electrical Double‐Layer Capacitors

et al. 2012

View full text Add to dashboard Cite

Energy-storage technologies, including electrical double-layer capacitors and rechargeable batteries, have attracted significant attention for applications in portable electronic devices, electric vehicles, bulk electricity storage at power stations, and "load leveling" of renewable sources, such as solar energy and wind power. Transforming lithium batteries and electric double-layer capacitors requires a step change in the science underpinning these devices, including the discovery of new materials, new electrochemistry, and an increased understanding of the processes on which the devices depend. The Review will consider some of the current scientific issues underpinning lithium batteries and electric double-layer capacitors.
