Maththew Burrard-Lucas,David G. Free,Stefan J. Sedlmaier,Jack D. Wright,Simon J. Cassidy,Yoshiaki Hara,Alex J. Corkett,Tom Lancaster,Peter J. Baker,Stephen J. Blundell,Simon J. Clarke +10 more
TL;DR: In this paper, the composition of the spacer layers present in iron-based superconductors is altered to increase the temperature below which they superconduct, and intercalating FeSe with molecular spacer layer is also shown to enhance the superconducting transition temperature.
Journal ArticleDOI
Interfacial reactivity and interphase growth of argyrodite solid electrolytes at lithium metal electrodes
Sebastian Wenzel,Sebastian Wenzel,Stefan J. Sedlmaier,Christian Dietrich,Wolfgang G. Zeier,Juergen Janek +5 more
TL;DR: Li 6 PS 5 X (X = Cl, Br, I) in contact with Li metal is investigated in this paper, where the stability of the argyrodite structure is investigated using an X-ray photoemission technique in combination with time-resolved impedance spectroscopy.
Journal ArticleDOI
Enhancement of superconducting transition temperature of FeSe by intercalation of a molecular spacer layer
Matthew Burrard-Lucas,David G. Free,Stefan J. Sedlmaier,Jack D. Wright,Simon J. Cassidy,Yoshiaki Hara,Alex J. Corkett,Tom Lancaster,P. J. Baker,Stephen J. Blundell,Simon J. Clarke +10 more
TL;DR: The synthesis of Li(x)( NH(2))(y)(NH(3))(1-y)Fe(2)Se(2), with lithium ions, lithium amide and ammonia acting as the spacer layer between FeSe layers, which exhibits superconductivity at 43(1) K, higher than in any FeSe-derived compound reported so far.
Journal ArticleDOI
Lithium ion conductivity in Li2S–P2S5 glasses – building units and local structure evolution during the crystallization of superionic conductors Li3PS4, Li7P3S11 and Li4P2S7
Christian Dietrich,Dominik A. Weber,Stefan J. Sedlmaier,Sylvio Indris,Sean P. Culver,Dirk Walter,Jürgen Janek,Jürgen Janek,Wolfgang G. Zeier +8 more
TL;DR: In this article, a detailed study on the local chemical nature of the thiophosphate building units within these materials was performed using Raman and 31P MAS NMR (Magic Angle Spinning- Nuclear Magnetic Resonance) spectroscopy.
Journal ArticleDOI
In Situ Monitoring of Fast Li-Ion Conductor Li7P3S11 Crystallization Inside a Hot-Press Setup
Martin R. Busche,Dominik A. Weber,Yannik Schneider,Christian Dietrich,Sebastian Wenzel,Thomas Leichtweiss,Daniel Schröder,Wenbo Zhang,Harald Weigand,Dirk Walter,Stefan J. Sedlmaier,Diane Houtarde,Linda F. Nazar,Jürgen Janek,Jürgen Janek +14 more
TL;DR: In this paper, a hot-press setup was proposed to facilitate the synthesis of solid electrolytes by combining in situ electrochemical impedance spectroscopy (EIS) with simultaneous temperature and pressure-monitoring.
