Broadband impedance spectroscopy of Li4Ti5O12: from nearly constant loss effects to long-range ion dynamics

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

Li4Ti5O12 (LTO) is known as one of the most robust and long-lasting anode materials in lithium-ion batteries. As yet, the Li-ion transport properties of LTO are, however, not completely understood. Here, we used broadband ...
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 ...
Rapid Low-Dimensional Li+Ion Hopping Processes in Synthetic Hectorite-Type Li0.5[Mg2.5Li0.5]Si4O10F2

Hiebl, Caroline; Loch, Patrick; Brinek, Marina; Gombotz, Maria; Gadermaier, Bernhard; Heitjans, Paul; Breu, Josef; Wilkening, H. Martin R. (Washington, DC : American Chemical Society, 2020)

Understanding the origins of fast ion transport in solids is important to develop new ionic conductors for batteries and sensors. Nature offers a rich assortment of rather inspiring structures to elucidate these origins. ...
