Several olivine phosphates were investigated in the last years as cathode materials for secondary lithium ion batteries. Among these compounds, LiFe <sub>x</sub> Co<sub>1∈-∈x</sub> PO<sub>4</sub> solid solutions might be interesting candidates because they should combine the high potential value of Co<sup>3+</sup>/Co<sup>2+</sup> (higher than 4.5 V vs Li<sup>+</sup>/Li) with the relatively high charge-discharge rate of LiFePO<sub>4</sub>. Solid solutions were prepared by solid-state route and characterised by X-ray powder diffraction, cyclic voltammetry, impedance spectroscopy and the Hebb-Wagner method. The results show that also low amount of iron induces high electronic conductivity in the solid solutions. © 2007 Springer-Verlag.
