Abstract: An additive for a positive electrode of a lithium secondary battery comprising a lithium transition metal oxide, Li3PO4 and Li5AlO4. The lithium transition metal oxide is doped with aluminum. The additive comprising Li3PO4 and Li5AlO4 together with the lithium transition metal oxide has a function of improving battery stability when applied to a positive electrode of a lithium secondary battery. Specifically, when a general lithium transition metal oxide is applied to the positive electrode of a lithium secondary battery, it may cause a side reaction with the electrolyte solution to generate gas in the battery, which may cause a problem with poor stability. However, Li3PO4 and Li5AlO4 are uniformly mixed with the lithium transition metal oxide or partially form a coating layer, and some aluminum is doped into the lithium transition metal oxide to inhibit the lithium transition metal oxide from causing side reactions with the electrolyte solution.
