Abstract: An object of the invention is to provide a method for economically and eco-friendly recovering an electrode raw material for a positive electrode and a negative electrode from a waste lithium ion secondary battery, which is formed by the pyrolysis of a waste lithium ion secondary battery, and an electrode raw material for a positive electrode and a negative electrode, obtained therefrom. To accomplish the object, a recycling method of a waste lithium ion secondary battery according to the invention may include (a) loading a waste lithium ion secondary battery into a pyrolysis furnace, (b) increasing the internal temperature of the pyrolysis furnace to induce self-heating of the waste lithium ion secondary battery, (c) maintaining a self-heating reaction of the waste lithium ion secondary battery, (d) discharging a first powder formed after completing the self-heating reaction of the waste lithium ion secondary battery, and (e) injecting the first powder into water, dissolving a lithium component included in the first powder, and separating and recovering a lithium aqueous solution, a powder settled in the lithium aqueous solution, and a floating material on the surface of the lithium aqueous solution, separately.

Abstract: An object of the present invention is to provide a method for recovering lithium from waste lithium-ion batteries that can recover lithium at a high recovery rate. The method for recovering lithium from waste lithium-ion batteries, the method including: a dissolution step of dissolving active material powder obtained by pre-processing waste lithium-ion batteries in a mineral acid; a neutralization step of adding at least one selected from the group consisting of sodium hydroxide and potassium hydroxide to a solution obtained in the dissolution step; a solvent extraction step of separating at least one metal excluding lithium from a solution obtained in the neutralization step by organic solvent extraction to obtain an alkali mixed salt aqueous solution; a separation step of separating each of a lithium salt and a salt of at least one selected from the group consisting of sodium and potassium from the alkali mixed salt aqueous solution; and a lithium recovery step of recovering lithium from a first lithium salt aqueous solution obtained in the separation step.
