A sebaconitrile-based electrolyte, 1 M LiBF4 /ethylene carbonate-dimethyl carbonate -sebaconitrile (25:25:50 by vol %) exhibits excellent electrochemical stability above 6 V against Li/ Li+. To confirm that the electrolyte can work at high voltages, LiFePO4 was intentionally charged at 6 V vs Li/ Li+. After the 6 V charging, the discharge capacity was 137 mAh/g and the coulomb efficiency was 91%. In addition, this oxidation resistant electrolyte was able to prove that Li 2 NiPO4 F has actually ca. 5.3 V redox potential against Li anode through cyclic voltammetry and charge/discharge cycle test.
