Abstract

Un material compuesto estructural con agentes reforzadores de carbono LiFePO4, puede ser sintetizado en una fase unica para alcanzar caracteristicas de celda superiores. Para este fin en la preparacion de un material activo catodico, los materiales de partida para la sintesis de un compuesto que tiene la formula LixFePO4, en donde 0 < x = 1, se mezclan conjuntamente, muelen y sinterizan. Un material de carbono se adiciona a uno de estos pasos. Corno materiales de partida para la sintesis de LixFePO4,, se usan Li3PO4, Fe3PO4, Fe3(PO4)2 o sus hidratos Fe3(PO4)2 nH2O. donde n es el numero de hidratos, y el contenido de Fe3+ en el hierro total de Fe3(PO4)2 o su hidrato Fe3(PO4)2nH2O) se ajusta a 61% en peso o menos.
