Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing process of both electrode materials of a lithium secondary battery which can improve a characteristic of charge and discharge. SOLUTION: After 1/2 Li2 CO3 , yCo(NO3 )2 .6H2 O, (1-y) Ni (NO3 )2 .6H2 O, C6 H8 O7 are dissolved in distilled water and brought into solution, NH4 OH is added to this solution, adjusted to pH = 3 to 4, and a citricsol is made, then a citratesol is heat-treated. Thus, things about manufacturing method of electrode materials for a lithium secondary battery and electrode materials of LiCo O2 and LiCoyNi1-y O2 (0
