Figure 1. LSV curves of (A) Li/graphite and (B) Li/Pt cells cycled in the electrolytes with & without LiDFOB additive. The inset is the enlarged view within the range of 3.5-4.6 V of (B); (C) Molecular orbital models and calculated HOMO/LUMO energy levels of EC, EMC, Li⁺-DFOB^-, and DFOB^-, respectively.
