LiFePO4 nanoparticles were incorporated with multi-walled carbon nanotubes (CNTs) via a facile one-step polyol process at low temperature. CNTs were uniformly embedded into LiFePO4 particles and formed a conductive network to enhance the electrochemical performance of the CNT-LiFePO4 nanocomposite cathode. Structural composition and morphology of the composite were investigated in details by X-ray diffraction (XRD), scanning and transmission electron microscopies (SEM, TEM). The electrochemical properties were analyzed in the voltage of 2.0 and 4.0 V by charge/discharge testing and cyclic voltammetry. Primary experimental results showed that these CNT-LiFePO4 nanocomposite cathodes exhibited enhanced electrochemical performance with both high capacity and good reversibility which has been clearly demonstrated in the Fig. 1.
