  "textContent": "A LiFePO4 carbon composite material is to be synthesized in a single phase satisfactorily to prevent the deterioration of the performance of the cathode active material from occurring and achieve superior cell characteristics. In preparing a cathode active material, starting materials for synthesis of a compound represented by the general formula LixFePO4, where 0 < x ≤ 1, are mixed, milled and a carbon material is added to the resulting mass at an optional time point in the course of mixing, milling and sintering. Li3PO4, Fe3(PO4)2 or its hydrates Fe3(PO4)2 .nH2O, where n denotes the number of hydrates, are used as the starting materials for synthesis of LixFePO4. The temperature of a product from said sintering is set to 305 DEG C or less when said product from said sintering is exposed to atmosphere.",
