New smelting reduction process to recover Co, Ni, Mn, and Li simultaneously from Li-ion batteries

Green Car Congress

Meanwhile, component Li 2 O in LiCoO 2 could be reduced to lithium metal vapor or converted into volatile lithium halides (LiF and LiCl) and subsequently be recovered in the flue dust. To provide a better reference for the industrial implementation, the proposed smelting process needs to be demonstrated on a pilot scale.
