The layered interface on the surface of the electrode in lithium-ion batteries enables rapid transport of lithium ions. The study shows that the uniform distribution of inorganic components in the solid electrolyte interphase (SEI) layer reduces the barriers to ion transport. The PAFE electrolyte achieves the lowest activation energy EaSEI for Li+ transport at the level of 48 kJ mol⁻¹, compared to 63 kJ mol⁻¹ for the basic BE electrolyte and 60 kJ mol⁻¹ for FE[1]. SEI in PAFE contains rich inorganic components such as Al₂O₃, LiF, Li₂O, Li₃N, Li₂CO₃ and Li₃P, which are uniform and increase mechanical strength, chemical stability and ionic conductivity[1]. Li₃N and Li₃P components with high conductivity for Li+ significantly accelerate transport at the interface[1]. Batteries with PAFE maintain a higher capacity at 60 °C and at 0 °C compared to BE[1]. Fluorine-rich SEI with well-dispersed LiF supports battery performance at fast charging and low temperatures down to -20°C[3].
