Abstract:

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.
