Coming soon: 2D ionic transport in Li4C60
Lithiated Buckminster fullerene (Li₄C₆₀) has previosuly been identified as a fast Li⁺ ion conductor. Through our NMR analysis we characterized both long-range and localized Li⁺ dynamics. We show that long-range ion dynamics is of 2D nature and is to be characterized by an activation energy as low as 0.26 eV.
Morphology aspects in understanding ionic conduction in thiophosphates
Amorphous vs. crystalline: The (exact) morphology may strongly influence overall ion dynamics in many cases. For Li3PS4, if prepared via a solvent-assisted approach, the change of ionic conductivity between a fully X-ray amorphous sample and a crystalline one obtained after annealing was much less influenced by this principle. See our latest study in Dalton Trans.: Morphology-dependent Li+ ion dynamics in X-ray amorphous and crystalline Li3PS4 prepared by solvent-assisted synthesis, J. Spychala, C. Mandl, K. Hogrefe, H. M. R. Wilkening, B. Gadermaier, Dalton Trans. (2025) in press.
