Figure 2. (A) Calculated HOMO/LUMO energies (eV) of EC, DEC, and PFP solvated with Li⁺ ions. (B) LSV curves of STD and 0.5% PFP-containing electrolytes measured with a graphite working electrode and Li metal as the counter electrode at a scanning rate of 0.1 mV s^-1. Highest occupied molecular orbital; LUMO: lowest occupied molecular orbital; EC: ethylene carbonate; DEC: diethyl carbonate; PFP: pentafluoropyridine; LSV: linear sweep voltammetry; STD: standard electrolyte.
