Co0.5TiOPO4 and LiFe0.4Mn0.6PO4 phosphates present the electrochemical features of anode and cathode of lithium ion batteries, respectively. The cobalt oxyphosphate exhibits a high capacity and a working potential around 1.5 V. During the first discharge, an irreversible lithiation reaction occurs while during the subsequent cycles, a good reversibility of the charge/discharge process was obtained with a stable specific capacity approaching 280 mAh/g even at high rate. For the LiFe0.4Mn0.6PO4 olivine, the electrochemical process occurs in two steps involving separately two redox couples: Mn3+/Mn2+ and Fe3+/Fe2+. The electrochemical lithiation/delithiation occur without significant changes in the structure. Even if the obtained capacity ( 110 mAh/g), is lower that the theoretical one, the coulombic storage efficiency is rather good ( 95%).
