Abstract

LiFePO₄/C materials were synthesized via an in situ coating on LiFePO₄ with 1-butyl-3-methylimidazolium dicyanamide [BMIm][N(CN)₂] as a carbon source. The electrode materials were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectra, Raman spectroscopy, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The results revealed that 1–2 nm carbon films were successfully coated on the LiFePO₄ particles. The electrochemical properties of LiFePO₄/C composite were investigated by cyclic voltammetry (CV) curves, electrochemical impedance spectra (EIS), and electrochemical analysis. The test results showed that the LiFePO₄/C composite possessed outstanding reversibility, cycle performance, and rate performance. The discharge capacities of LiFePO₄/C were 161.5 mAh g⁻¹ at 0.1 C and 143.6 mAh g⁻¹ at 1 C, respectively. The excellent electrochemical properties of the LiFePO₄/C electrode were mainly due to the thin, uniform, and highly graphitized carbon films.
