  • Publication number: 20120312126
    Abstract: Provided is a valuable-metal recovery method for recovering metals from lithium ion batteries using comparatively simple equipment and without using a cumbersome process. In said method, a positive electrode material from lithium ion batteries, containing lithium and a transition metal, is dissolved in an acidic solution, thereby generating lithium ions and ions of the transition metal in the acidic solution. Said acidic solution and a recovery liquid are then made to flow with an anion-permeable membrane interposed therebetween, causing the lithium ions to permeate from the acidic solution to recovery solution. Lithium ions are then recovered from the recovery liquid containing dissolved lithium ions.
