  "textContent": "An LiFePO4 carbon composite material is to be synthesized in a single phase to realize superior cell characteristics. To this end, in the preparation of a cathode active material, starting materials for synthesis of a compound having the formula LixFePO4, where 0 < x ≤ 1, are mixed together, milled and sintered. A carbon material is added at one of these steps. As the starting materials for synthesis for LixFePO4, Li3PO4, Fe3PO4, Fe3(PO4)2 or its hydrate Fe3(PO4)2.nH2O), where n is the number of hydrates, are used, and the content of Fe in the total iron in Fe3(PO4)2 or its hydrate Fe3(PO4)2.nH2O) is set to 61 wt% or less.",
