In this article, a extraction method of metal in spent Li-ion batteries was investigated. The procedure includes two steps: dissolvent the metal in electrode powder using sulfuric acid 8 M in 3 hours at 80oC; extraction of the dissolved solution by Cyanex 272 0.4 M in kerosen at pH 6 and room temperature for 30 minutes. The experiment results show the metal (Ni, Co) extraction efficiency is at 90% - 96%. This exhibition has opened a positive direction to recover the metals in spent Li-ion battery.
