Electrochemical process for recovery of metallic Mn from waste LiMn2O4-based Li-ion batteries in NaCl?CaCl2 melts
文献摘要：
A new method is proposed for the recovery of Mn via the direct electrochemical reduction of LiMn2O4 from the waste of lithium-ion batteries in NaCl?CaCl2 melts at 750℃. The results show that the LiMn2O4 reduction process by the electrochemical method on the coated electrode surface occurs in three steps: Mn(IV) → Mn(III) → Mn(II) → Mn. The products of this electro-deoxidation are CaMn2O4, MnO, (MnO)x(CaO)1?x, and Mn. Metal Mn appears when the electrolytic voltage increases to 2.6 V, which indicates that increasing the voltage may promote the deoxidation reaction process. With the advancement of the three-phase interline (3PI), electric deoxygenation gradually proceeds from the outer area of the crucible to the core. At high voltage, the kinetic process of the reduction reaction is accelerated, which generates double 3PIs at different stages.
