The energy density of lithium-ion batteries can be raised by increasing the redox potential of the positive electrode. This can be done in principle by substituting oxygen in commonly used lithium transition metal oxides with the more electronegative

Unravelling the mechanism of lithium insertion into and extraction from trirutile-type LiNiFeF6 cathode material for Li-ion batteries
Autor: Christoph Dräger, Georg Lieser, Jatinkumar Rana, Holger Geßwein, Sylvio Indris, Gerhard Schumacher, Sven Glatthaar, Joachim R. Binder, Helmut Ehrenberg, L. de Biasi, Reiner Mönig
Publikováno v: CrystEngComm. 17:6163-6174
LiNiFeF6 was used as cathode material in lithium-ion cells and studied by in situ X-ray diffraction (XRD), in operando X-ray absorption spectroscopy (XAS) and 7Li MAS NMR spectroscopy. An optimised electrochemical in situ cell was employed for the st

Sol–gel processing and electrochemical characterization of monoclinic Li3FeF6
Autor: Holger Geßwein, Melanie Schroeder, Georg Lieser, Joachim R. Binder, Sven Glatthaar, Volker Winkler, Murat Yavuz
Publikováno v: Journal of Sol-Gel Science and Technology. 71:50-59
To find new cathode materials for future applications in lithium-ion batteries, lithium transition metal fluorides represent an interesting class of materials. In principle the Li intercalation voltage can be increased by replacing oxygen in the cath
