Resumen de: EP4685113A1
The present invention provides a lithium recycling method for waste lithium iron phosphate batteries, comprises: placing black powder of a positive electrode of a waste lithium iron phosphate battery in a roasting processing furnace filled with protective gas for a roasting reaction. During this, the input chlorine flow rate is adjusted based on the mixture in the roasting processing furnace to control the roasting reaction temperature at 50-300°C. The roasted product is then immersed in water to obtain a roasted product solution. Suction filtration of the roasted product solution yields a filtrate. Evaporation concentration followed by drying of the filtrate prepares lithium chloride crystals. This one-step low-temperature roasting, with temperature controlled by adjusting the input chlorine flow rate, converts the lithium element into water-soluble lithium chloride. The method is simple, efficient, low in energy consumption, achieves over 95% lithium element recycling rate, and has significant industrial application value.
