Abstract
Polyaniline (PANI) was synthesized by adsorption double oxidizer method, and then reduced with N2H4·H2O (r-PANI), doped with HClO4 (d-PANI). PANI with different states was combined with lithium iron phosphate (LiFePO4) in water-based slurry to form PANI/LFP composites. Some physical characterization methods (Fourier transform infrared spectroscopy analysis, scanning electron microscope) were used to analyze the morphology and structure of the composites. The electrochemical properties were characterized by cyclic voltammetry, impedance spectroscopy, galvanostatic charge/discharge, and rate capability. The specific capacity of the r-PANI/LFP composite reached 154 mAh/g, which was 4.1% higher than that of pure LFP, and the coulombic efficiency of the battery was close to 100%. Under the higher discharge rate conditions, the r-PANI/LFP composite still released a good reversible capacity. Moreover, the cyclability and rate capability of the r-PANI/LFP composites are better than that of pure LFP.
