  • Comparison of 3D and 2D Li Diffusion in Cubic and Hexagonal LixTiS2 – A Study by Solid State 7Li NMR Methods 
    Wilkening, Martin; Heitjans, Paul (Leipzig : Universität Leipzig, 2007-08-29)
    Li diffusion in spinel-type structured cubic and hexagonal LixTiS2 with x = 0.6 and 0.7, respectively, was investigated by solid state NMR spectroscopy. In layered hexagonal LixTiS2, Li diffusion is known to be confined ...
  • Ion dynamics in a new class of materials: nanoglassy lithium alumosilicates 
    Stanje, B.; Bottke, P.; Breuer, S.; Hanzu, I.; Heitjans, Paul; Wilkening, M. (Bristol : IOP Publishing Ltd., 2018)
    In many cases nanocrystalline materials, prepared through high-energy ball milling, reveal enhanced ion dynamics when compared to the situation in the coarse-grained analogues. This effect, which has particularly been seen ...
  • NMR Studies of Lithium Diffusion in Li3(NH2)2I over Wide Range of Li+ Jump Rates 
    Skripov, Alexander V.; Volgmann, Kai; Chandran, C. Vinod; Skoryunov, Roman V.; Babanova, Olga A.; Soloninin, Alexei V.; Orimo, Shin-Ichi; Heitjans, Paul (Berlin : Walter de Gruyter, 2017)
    We have studied the Li diffusion in the complex hydride Li3(NH2)2I which appears to exhibit fast Li ion conduction. To get a detailed insight into the Li motion, we have applied 7Li nuclear magnetic resonance spectroscopy ...
  • Solid-State NMR Spectroscopy Study of Cation Dynamics in Layered Na2Ti3O7 and Li2Ti3O7 
    Volgmann, Kai; Werth, Vanessa; Nakhal, Suliman; Lerch, Martin; Bredow, Thomas; Heitjans, Paul (Berlin : Walter de Gruyter, 2017)
    Ti-based materials exhibit suitable properties for usage in secondary Li-and Na-ion batteries and were in the focus of several electrochemical and ion conductivity studies. A material of such interest is layer-structured, ...
  • Solid-State NMR to Study Translational Li Ion Dynamics in Solids with Low-Dimensional Diffusion Pathways 
    Volgmann, Kai; Epp, Viktor; Langer, Julia; Stanje, Bernhard; Heine, Jessica; Nakhal, Suliman; Lerch, Martin; Wilkening, Martin; Heitjans, Paul (Berlin : Walter de Gruyter, 2017)
    Fundamental research on lithium ion dynamics in solids is important to develop functional materials for, e.g. sensors or energy storage systems. In many cases a comprehensive understanding is only possible if experimental ...
