PURPOSE: A positive electrode material of a lithium secondary battery is provided to ensure stable structure and electrochemical characteristic, and to realize high capacity while suppressing transition to a spinel phase. CONSTITUTION: A positive electrode material of a lithium secondary battery is a monoclinic material occurring a bond of oxygen through partial substitution of transition metal containing low valent metal or model metal to chemical formula: LiM'M"O3. The positive electrode material of a lithium secondary battery has a structure of LiM'M"O3 comprises any one selected from Li_1.905Mn_0.795Mg_0.075Cr_0.225O_5.91. |
