Title:
リチウムまたはナトリウムイオン電池の活物質からリチウムまたはナトリウムをそれぞれ回収する方法
Document Type and Number:
Japanese Patent JP7465564
Kind Code:
B2
Abstract:
Disclosed herein is a method of recovering lithium or sodium from an active material of a lithium or sodium ion battery. In a preferred embodiment, the method comprises a redox-targeting reaction of a used active material LiFeP04 with a redox mediator [Fe(CN)6]3− in a tank to produce lithium ions, circulating the reacted redox solution into a cell to regenerate said redox mediator and enabling said lithium ions to migrate through a membrane towards a cathode wherein said lithium ions are captured as LiOH through an electrochemical reaction.
