In this work, we report morphological and electrical characterizationsof highly crystalline LiCuXFe1−XPO4 nanoparticles synthesized by the hightemperature (380 ◦C) thermal decomposition method of the organo-metallic precursors.The mean diameter of the studied nanoparticles was 30 - 40 nm. The Cu/Ferelations of 0, 0.001 and 0.042 for three studied samples were obtained from PIXEspectroscopy. Crystallographic and morphological studies were performed using X-raydiffraction, Transmission and High-resolution Electron Microscopy techniques. Weinvestigate the effect of the incorporation of copper on the electric transport propertiesof this highly crystalline nanometric system, using impedance spectroscopy and DCtransport techniques. The experimental evidences allow us to conclude that in thefrequencies range of f < 1 kHz, the transport is dominated by the diusion of Li andthe presence of Cu atoms in the systems hinders this transport mechanism, despite thehigh crystallinity of the system.
