Ag is introduced to the surface of LiFePO4 prepared from liquid phase and heated at different temperatures. SEM, XRD and electrochemical characterization are used to compare the differences between LiFePO4 and LiFePO4/Ag. The results are discussed from the viewpoint of impedance of the cathode composite. With increase of the particle size, Ag shows stronger function as conductor in the composites.
