Specifically, acid leaching has been extensively studied to recover metals like Li, Ni, and Co from lithium-ion batteries. However, traditionally, non-selective leaching is used to separate all the valuable metals from the cathode. As a result, the leachate must be processed further to recover high purity metals.
On the basis of the above experiments, in situ leaching of waste lithium batteries was also carried out. Under the optimal leaching conditions (current density of 400 A/m 2, active material: H 2 O 2 = 200 g/L), as shown in Fig. 6, after 6 h of leaching, the leaching rate of Li + reaches 99.85 % while that of Co 2+ is 43.87 %.
As shown in Fig. 7 (a), the active material agglomeration on the positive electrode of the waste lithium battery is serious before the leaching, however, the active material on the positive electrode surface dissolves after the leaching, leaving only the aluminum foil substrate ( Fig. 7 (b)).
The focus of our study was to present a novel approach for the treatment of lithium ion battery (LIBs) lixiviates using nanofiltration, with the objective to recover a pure fraction of lithium with a high recovery as first step of a hydrometallurgical LIBs recycling process.
Lithium can be selectively leached with water, while other products remain undissolved. Fan et al. were the first to suggest roasting LiBs using salt-assisted chlorination. A combination of NH 4 Cl roasting and water leaching was used for the selective recovery of lithium . Almost 95% of the Li and Co were recovered below 350 °C.
