An ion storage compound of cathode material and method for preparing the same are disclosed. The method for preparing the ion storage compound comprises steps of providing a first reactant having a formula of A<SUB>3x</SUB>M1<SUB>2y</SUB>(PO<SUB>4</SUB>)<SUB>3</SUB>, providing a second reactant being at least one compound selected from the group consisting of SiC, BN and metal oxide having a formula of M2<SUB>a</SUB>O<SUB>b</SUB>, and reacting the first reactant with the second reactant to form the ion storage compound. A is at least one element selected from the group consisting of Groups IA, IIA and IIIA; each of M1 and M2 is at least one element selected from the group consisting of Groups IIA, IIIA, IVA and VA and transition metal elements, respectively; and 0<x<=1.2, 1.2<=y<=1.8, 0<a<=7, and 0<b<=6.
