Polypyrrole–FePO 4 powder was synthesized by an oxidative polymerization of pyrrole monomer on the surface of FePO 4 powder. The polymerization reaction was initiated using hydrogen peroxide in an acidified solution and catalysed with Fe 3+ . The samples were investigated by light microscopy (LM), scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDX). These methods confirmed the presence of polypyrrole on FePO 4 particles and its homogeneous distribution in the composite material. To determine the PPy content in the PPy–FePO 4 composites a thermogravimetric analysis was used. Cyclic voltammetry curves (CV) were measured and compared in a non-aqueous lithium salt solution for electrodes consisting of pellets made from pure FePO4 and FePO 4 /PPy. Electrochemical impedance spectroscopy (EIS) showed that coating of PPy significantly decreases the charge transfer resistance of PPy–FePO 4 electrodes.
