Abstract

The present invention relates to a composition for recovering battery materials or disabling a battery and, more specifically, to a composition for recovering battery materials or disabling a battery, the composition being used when recovering, through chemical discharge, main materials in a used battery. The composition for extracting lithium in an anode of a battery contains a lithium-extraction solution (LeS), and the LeS contains an antisolvent that has a low solubility for a lithium compound so as to crystallize a lithium ion in a solution into a lithium compound.

Abstract

The present invention relates to a method for recovering an iron phosphate battery material, the method comprising: a step (S1) of inducing a chemical discharge by opening an outer pouch of a used iron phosphate battery in a solution; and a step (S2) of recovering a battery material from the solution after the chemical discharge. The method for recovering an iron phosphate battery material can recover the main materials from a used iron phosphate battery with high efficiency and speed at a low cost.
