Abstract

This work intends to investigate the possibilities of cobalt leaching from spent lithium ion batteries by electrochemistry technique. A new method was put forward and a self-designed leaching apparatus was made. The series experiments demonstrate that the ferrous ion can improve cobalt leaching from spent lithium ion batteries and the circle of Fe3+/Fe2+ is possible. Higher voltage and appropriate amount of ferric sulfate can get better cobalt leached percentage.
