N2 - Merck KGaA developed LiPF3(CF2CF3)3, (LiFAP) as a new electrolyte that can replace the commonly used LiPF6 in Li-ion batteries. Vinylene carbonate and Li salicylato borate (Merck's AD25) were studied as additives for LiFAP solutions in mixtures of ethylene, dimethyl, and diethyl carbonates with composite graphite and LiMn2O4 electrodes. The tools for this study included voltammetry (fast and slow scan rates), chronopotentiometry, impedance spectroscopy, electron microscopy, Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy. It was found that LiFAP solutions containing VC were superior for both graphite and LiMn2O4 (spinel) electrodes. The effect of additives on the electrodes' performance can be clearly attributed to their impact on the surface chemistry of these electrodes.
