Hydrometallurgical Process to Recover Cobalt from Spent Li-Ion Batteries

The growth of the lithium-ion battery industry requires a secure supply raw materials and appropriate end-of-life management batteries. In almost five years, global cobalt consumption has increased by nearly 30%, driven mainly rechargeable Consequently, several risks have been identified for cobalt, in particular growing demand electric vehicles, which could exceed current production. Therefore, research into recovery this critical metal, from industrial or urban waste, is particularly important years to come. study, recovered leachate hydroxide form. thermodynamic simulations performed with Visual Minteq showed that it was possible recover 99.8% (II) at 25 °C. Based on these results, experiments were conducted validate hypotheses put forward compare results obtained performed. Experimentally, operating parameters studied determine optimal conditions recovery, terms yield, filterability, selectivity. Results batch reactor allowed determination temperature be applied continuous reactor. precipitation carried out under different pH conditions. It then yield filterability. working 9 would effectively meet desired criteria. Indeed, close 100% filtration flow rate three times higher. allow better understanding precipitation.
