Dynamics of the Extended and Intermediate Range Order in Model Polymer Electrolyte Poly(Ethylene Oxide) and Lithium Bis(Trifluoromethanesulfonyl)imide

April 17, 2023
Author(s)
Peter Falus, Antonio Faraone, Stephan Forster, Kunlun Hong, Michael Ohl
The dynamics of lithium ions and polymer chains were investigated at the molecular scale in the model polymer electrolyte Poly (Ethylene Oxide) (PEO)/Lithium bis(trifluoromethanesulfonyl)imide as a function of temperature. This system is known to present

Super Charge Separation and High Voltage Phase in Na x MnO 2

December 12, 2018
Author(s)
Xi Chen, Yichao Wang, Kamila Wiaderek, Xiahan Sang, Olaf Borkiewicz, Karena Chapman, James LeBeau, Jeffrey W. Lynn, Xin Li
Na xMnO 2 shows Mnu3+^ and Mn^ 4+ charge separation with charge stripe ordering upon Na de-intercalation at x=5/8, similar to many colossal magnetoresistance materials. We show in this paper that, surprisingly, at lower Na compositions of 5/8 >x less than
