A method for recycling waste lithium iron phosphate batteries relates to a battery recycling method. The method provided by the invention aims to provide a battery recycling method which is simple in process and low in cost. The method comprises the following steps of: removing residual electric quantity of a waste lithium iron phosphate battery, taking out the cell of the battery and crashing the cell into fragments, soaking the cell fragments in sodium hydroxide solution and stirring; and then performing filtering, washing, drying and vibratory screening so as to obtain pure alumium, pure copper and a diaphragm on a screen, recycling alumium and copper through smelting so as to obtain mixed powder under the screen, cleaning the mixed powder by using acidic solution, performing drying and thermal treatment, adjusting the mol ratio of lithium to iron to phosphorus to carbon, and then performing ball milling, drying and roasting, thereby obtaining a lithium iron phosphate anode material. The method for efficiently recycling the waste lithium iron phosphate batteries provided by the invention is simple in process, low in production cost and quick in taking effect.
