Abstract
This study examined the properties of 1 wt.% vinylene carbonate (VC), vinyl ethylene carbonate (VEC), and diphenyl octyl phosphate (DPOF) additive electrolytes as a promising way of beneficially improving the surface and cell resistance of Li-ion batteries. Surface film formation on the negative and positive electrodes was analyzed by electrochemical impedance spectroscopy (EIS), Fourier transform infrared (FT-IR) spectroscopy, and scanning electron microscopy (SEM). In conclusion, EIS, FT-IR spectroscopy and SEM results confirmed that DPOF is an excellent additive to the electrolyte in the Li-ion batteries due to the improved co-intercalation of the solvent molecules.
