    摘要： Provided is a cathode active material having a composition represented by the following Formula I: LiFe(P1-XO4) (I) wherein a molar fraction (1-x) of phosphorus (P) is in the range of 0.910 to 0.999, to allow operational efficiency of the cathode active material to be leveled to a lower operational efficiency of an anode active material and improve energy density of the cathode active material. Furthermore, a cathode active material, wherein a molar fraction (1-x) of phosphorus (P) is lower than 1, contains both Fe2+ and Fe3+, thus advantageously preventing structural deformation, improving ionic conductivity, exhibiting superior rate properties and inhibiting IR drop upon charge/discharge, thereby imparting high energy density to batteries.

Furthermore, the olivine-type lithium iron phosphate has the high porosity, thus allowing at least a portion of the secondary particles to be deformed and converted into primary particles in the process of pressing to fabricate electrodes and preventing deterioration in ionic conductivity due to the large particle diameter.
