Абстракт

The present invention aims at improving a re- covery rate of a positive-pole active substance and pre- venting a recovery loss of valuable metals when a posi- tive-pole active substance is separated from a lithium ion battery. In the present invention, a material resulting from battery dismantling obtained by dismantling a lithium ion battery is stirred using a surfactant solution, whereby a positive-pole active substance is separated from a pos- itive-electrode substrate. Also, it is preferable that an al- kaline solution is added to a positive-electrode material of a material resulting from battery dismantling, thereby dissolving a positive-electrode substrate to which a pos- itive-pole active substance adheres to obtain a slurry con- taining the positive-pole active substance, and a sur- factant solution is added to the slurry to disperse the pos- itive-pole active substance in the slurry, whereby the pos- itive-pole active substance is separated from the alkaline solution.
