  • 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 ...
  • Local Ion Dynamics in Polycrystalline β-LiGaO2: A Solid-State NMR Study 
    Chandran, C. Vinod; Volgmann, Kai; Nakhal, Suliman; Uecker, Reinhard; Witt, Elena; Lerch, Martin; Heitjans, Paul (Berlin : Walter de Gruyter, 2017)
    Solid-state nuclear magnetic resonance spectroscopy is an efficient technique to characterize dynamics and structure of materials. It has been widely used to elucidate ion dynamics in lithium ion conductors. Fast moving ...
  • 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, ...
