A positive electrode active material is provided to increase electric capacity of a battery, to decrease the content of conductive materials and to improve electrode density high discharge capability by comprising metal oxynitride and metal nitride which have high conductivity. A positive electrode active material comprises a lithium metal phosphate-based compound represented by formula 1: LiMPO4, and at least one selected from the group consisting of metal oxynitride, metal nitride and their mixture. In chemical formula 1, M is one metal selected from the group consisting of Fe, Ti, V, Cr, Co and Ni. |
