We study the stability of several diglyme-based electrolytes in sodium|sodium and sodium|graphite cells. The electrolyte behavior for different conductive salts [sodium trifluoromethanesulfonate (NaOTf), NaPF6, NaClO4, bis(fluorosulfonyl)imide (NaFSI), and sodium bis(trifluoromethanesulfonyl)imide (...

Conductivities of electrolyte solutions prepared with LiPF 6 and LiClO 4 are comparable, but lower activation energy is required for LiClO 4. A flat maximum of conductivity at about 50% (v/v) in EC is observed when the composition of the mixed solvent is varied. A high value, independent ...
Moreover, important findings regarding activation processes in the presence of a new phase transition and protective electrolyte interphase layer are revealed using ab initio density function theory calculation and in situ potentio-electrochemical impedance spectroscopy. The detailed complex redox mechanism ...

One key finding of this work is that electrolyte solutions based on ether solvents like diglyme can remove Sb﹊ons from Sb2O3 during cycling. Diglyme has the ability to coordinate and extract Sb3+ during the oxidation of Sb2O3. This leads to contaminations of all cell components and a ...
Herein, the electrochemical performance of half cells using Na0.66Ni0.33xZnxMn0.67O2(x=0, 0.07 and 0.14) cathodes in diglyme-based electrolyte are first studied. For x=0.07, high discharge capacities of 120 and 80mAhg1at 15 and 150mAg1, respectively are measured, with stable operation voltage...
