The invention provides a method for recycling a waste lithium cobaltate positive electrode, and the method comprises the following steps: step (1), mixing the lithium cobaltate positive electrode, an acidic solution of hydrogen peroxide, a phosphate source, an iron source, lithium nitrate and citric acid, and drying to obtain a first precursor, wherein the molar ratio of lithium, iron and cobalt elements in the first precursor is 1.05 to 1.15: x: (1-x), and x is greater than 0 but less than 1; step (2), sequentially carrying out ball milling and first calcination on the first precursor to obtain a second precursor; and step (3), mixing the second precursor with the citric acid, and carrying out second calcination to obtain an iron cobalt lithium phosphate positive electrode material, wherein the first calcination and the second calcination are carried out in an inert gas or a nitrogenatmosphere. The discharge specific capacity of the positive electrode material obtained by the method provided by the invention can reach 135 mAh / g or more.
