QIAO Xiu-li, TIAN Jun, MA Song-yan, et al. The Recovery of Cobalt from the Spent Lithium-ion Batteries Using Acid Leaching Method[J]. 2011, 16(2): 106-109.DOI:
The metal cobalt in lithium-ion battery cathode material is recycled by hydrochloric acid-hydrogen peroxide
sulfuric acid-hydrogen peroxide and nitric acid-hydrogen peroxide as the leaching solution
respectively.The influences of concentration
temperature
amount of hydrogen peroxide
reaction time
solid-liquid ratio on leaching efficiency of cobalt ion are studied.Experimental results have shown that the hydrochloric acid-hydrogen peroxide system is the most appropriate leaching solution.The optimum process ...
