NOVELTY - Recycling of waste lithium iron phosphate power battery comprises discharging, moving in vacuum glove box charged with nitrogen protection, moving out cover board and battery groove, leaching with water or roasting and recycling, moving out negative electrode and diaphragm from electric core, recycling diaphragm as waste plastic, calcining negative electrode, screening and separating copper coils and harmless active powder substances, and cleaning positive electrode in glove box with solvent, drying, screening and assorting with new negative electrode to make new battery.    USE - Method of recycling waste lithium iron phosphate power battery.    ADVANTAGE - The method simply classifies and recycles parts of waste power battery without need for complicated physic or chemical courses, and provides recycled lithium iron phosphate positive electrode that can be used as normal pole without separating active substances and aluminum coils, thus improving effective utilization ratio of lithium iron phosphate positive electrode.    DETAILED DESCRIPTION - Recycling of waste lithium iron phosphate power battery comprises:    (A) discharging completely the battery, moving to vacuum glove box charged with nitrogen protection, opening mechanically the cover board of battery, and taking out to fill in electric core of battery groove;    (B) moving cover board and battery groove out of glove box, placing in closed space, leaching with water or roasting to react and decompose the electrolyte adhered on cover board and wall of battery groove shell, and recycling cover board and polypropylene plastic, steel or aluminum material of battery groove;    (C) moving negative electrode and diaphragm from electric core out of vacuum glove box, recycling diaphragm as waste plastic, and calcining negative electrode at high temperature, screening and separating copper coils and harmless active powder substances and utilizing copper coils as waste metal or melting and reusing them;    (D) cleaning positive electrode left in glove box with carbonic ester micromolecular solvent, acetone or N-methyl pyrrolidone to remove lithium hexafluorophosphate adhered on surface; and    (E) drying cleaned positive electrode piece in drying box with solvent recycling system, screening and assorting with new negative electrode piece to make new battery.
