This paper describes the synthesis and the properties of a kinetically improved LiFePO4 cathode material. The novel aspect of the synthesis is based on a critical step involving the dispersion of metal (e.g., copper or silver) at a very low concentration (1 wt%). This metal addition does not affect the structure of the cathode but considerably improves its kinetics in terms of capacity delivery and cycle life. Such an enhancement of the electrochemical properties has been ascribed to a reduction of the particle size and to an increase of the bull, intra- and interparticle electronic conductivity of LiFePO4, both effects being promoted by the finely dispersed metal powders. This improved conductivity favors the response of LiFePO4, thus substantiating its interest as new cathode for advanced lithium ion batteries. (C) 2002 The Electrochemical Society.
