Direct Assessment of Ultralow Li+ Jump Rates in Single Crystalline Li3N by Evolution-Time-Resolved 7Li Spin-Alignment Echo NMR

Gadermaier, Bernhard; Hogrefe, Katharina; Heitjans, Paul; Wilkening, H. Martin R. (Weinheim : Wiley-VCH, 2021)

Diffusion processes of small cations and anions play important roles in many applications such as batteries and sensors. Despite the enormous progress we have witnessed over the past years in characterizing the irregular ...
Improved Electrochemical Performance of Modified Mesocarbon Microbeads for Lithium-Ion Batteries Studied using Solid-State Nuclear Magnetic Resonance Spectroscopy

Bösebeck, Katharina; Chandran, C. Vinod; Licht, Björn K.; Binnewies, Michael; Heitjans, Paul (Weinheim : Wiley-VCH Verlag, 2016)

Lithium-intercalating materials such as graphite are of great interest, especially for application in lithium-ion batteries. In this work we present an investigation of the electrochemical performance of mesocarbon microbeads ...
Li Ion Dynamics in Al-Doped Garnet-Type Li7La3Zr2O12 Crystallizing with Cubic Symmetry

Kuhn, Alexander; Choi, Joon-Yong; Robben, Lars; Tietz, Frank; Wilkening, Martin; Heitjans, Paul (Berlin : Walter de Gruyter, 2012)

Lithium-ion dynamics in the garnet-type solid electrolyte “Li7La3Zr2O12” (LLZ) crystallizing with cubic symmetry was probed by means of variable-temperature 7Li NMR spectroscopy and ac impedance measurements. Li jump rates ...
