a b s t r a c tIn the current study, an environmental benign process namely mechanochemical approach was developed for cobalt and lithium recovery from spent lithium-ion batteries (LIBs). The main merit of the process was that neither corrosive acid nor strong oxidant was applied. In the proposed process, lithium cobalt oxide (obtained from spent LIBs) was firstly co-grinded with various additives in a hermetic ball milling system, then Co and Li could be easily recovered by a water leaching procedure. It was found that EDTA was the most suitable co-grinding reagent, and 98% of Co and 99% of Li were respectively recovered under optimum conditions: LiCoO 2 to EDTA mass ratio 1:4, milling time 4 h, rotary speed 600 r/min and ball-to-powder mass ratio 80:1, respectively. Mechanisms study implied that lone pair electrons provided by two nitrogen atoms and four hydroxyl oxygen atoms of EDTA could enter the empty orbit of Co and Li by solid-solid reaction, thus forming stable and water-soluble metal chelates Li-EDTA and Co-EDTA. Moreover, the separation of Co and Li could be achieved through a chemical precipitation approach. This study provides a high efficiency and environmentally friendly process for Co and Li recovery from spent LIBs.

The amount of each reagent added was calculated to provide the ions and the pH value corresponding to the solution found in a previous study (Provazi et al, 2011). Table 1 provides the values of concentrations in mgL -1 of metal ions and the final pH of the electrolytic solution.…”

“…The hydrometallurgical process has been widely used for separation of the metals contained in batteries (Sayilgan et al, 2009;Li et al, 2009;Vatistas et al, 2001;Provazi et al, 2011). The solution from the hydrometallurgical treatment process for battery recycling can be a potentially important source of manganese.…”

-This work aims to verify the possibility of using depleted batteries as a source of manganese dioxide applying the electrolytic process. An electrolyte solution containing the following metal ions was used: Ca (270 mgL -1 ), Ni (3.000 mgL -1 ), Co (630 mgL -1 ), Mn (115.3 mgL -1 ), Ti (400 mgL -1 ) and Pb (20 mgL -1 ). The production of electrolytic manganese dioxide (EMD) was performed through electrolysis at 98 °C (± 2 °C) applying different current densities (ranging from 0.61 A.dm -2 to 2.51 A.dm -2 ). The materials obtained were analyzed through X-ray fluorescence spectrometry, X-ray diffraction, specific surface area (BET) and scanning electron microscopy (SEM). The best results regarding the current efficiency, purity grade and specific surface area were obtained with a current density ranging between 1.02 A.dm -2 and 1.39 A.dm -2 . The allotropic ε-MnO 2 variety was found in all tests.
