    • Abstract

       

      The P3HT grafted on CNTs to form the P3HT-$g$-CNTs nanocomposites was synthesized and their morphologies, structure have been characterized via the sedimentation test, scanning electron microscopy (SEM), X-raydiffraction (XRD) and transmission electron microscopy (TEM). The results showed that the P3HT-$g$-CNTs has a better thermal stability than that of the P3HT/CNTs blend. The nanocomposite based on P3HT-g-CNTs and doped spinel LiNi$_{0.5}$Mn$_{1.5}$O$_4$ (LNMO) have been fabricated via mixing process. The structure and morphologies of LNMO/P3HT-$g$-CNTs nanocomposites have also been performed by SEM, XRD and TEM. The electrochemical performance of LNMO/P3HT-$g$-CNTs nanocomposites as cathode materials of lithium-ion batteries were investigated by cyclic voltammetry and electrochemical impedance spectroscopy and exhibited the high diffusion of lithium ions in the charge–discharge process.
