PURPOSE: A manufacturing method of anodic active materials for lithium secondary batteries and an anodic active material for the lithium secondary battery manufactured by the same are provided to increase productivity and tap density. CONSTITUTION: A manufacturing method of anodic active materials for lithium secondary batteries comprises the following steps: manufacturing a solution by agitating salt of chemical formula(1) and ammonia with distilled water; manufacturing metal multi-hydroxide by mixing the manufactured solution with hydrate solution and a complexing agent as nickel salt, mixed solution of manganese salt, cobalt salt, and a pH adjusting agent using co-precipitation method; manufacturing lithium metal composite hydroxide by mixing the metal multi hydroxide with lithium compound; and manufacturing the lithium metal oxide by sintering the lithium metal multi hydroxide. The chemical formula(1) is as follows: C^+X^-. Here, C^+ is one or more selected from Na, K, NH4 and Li. X^- is one or more selected from SO4^(2-), NO3^-, Cl^-, CO3^(2-), and COO^-.
