The present invention relates to an olivine-type cathode active material precursor for a lithium battery including MXO 4-z B z (wherein, M is one element selected from the group consisting of Fe, Ni, Co, Mn, Cr, Zr, Nb, Cu, V, Ti, Zn, Al, Ga, Mg, B, and the combination thereof, X is one element selected from the group consisting of P, As, Bi, Sb, and the combination thereof, B is one element selected from the group consisting of F, S, and the combination thereof, and 0≤z≤0.5) particles with a particle size of 1 to 20μm, a tap density of 0.8 to 2.1g/cm 3 , and a specific surface area of 1 to 10 m 2 /g. The olivine-type cathode active material for a lithium battery prepared by utilizing the olivine-type cathode active material precursor has an excellent particle crystallinity, electrochemical property, and capacity characteristics per unit volume due to both the large particle size and the high tap density thereof. |
