Abstract

Smelting reduction of spent lithium-ion batteries results in metallic alloys, slag, and dust containing Li(I). Precipitation of Li₂CO₃ was performed using the synthetic leachate of the dust. Herein, the effects of the precipitant and addition of non-aqueous solvents on the precipitation of Li(I) were investigated. Na₂CO₃ was a more effective precipitating agent than (NH₄)₂CO₃ owing to the hydrolysis reaction of dissolved ammonium and carbonate. The addition of acetone or ethanol improved the Li(I) precipitation percentage for both the precipitants. When using (NH₄)₂CO₃, the Li(I) precipitation percentage increased at a solution pH of 12. Under the same conditions, the Li(I) precipitation percentage using Na₂CO₃ was much higher than that using (NH₄)₂CO₃.

폐리튬이온전지를 고온에서 용융환원하면 금속혼합물, 슬라그와 리튬(I)을 함유한 분진이 발생한다. 분진의 침출 합성액을 이용하여 Li₂CO₃ 석출실험을 수행했다. 석출제의 종류와 비수용액의 첨가가 석출에 미치는 영향을 조사했다. (NH₄)₂CO₃에서 해리된 암모늄과 탄산이온의 수화반응으로 인해 Na₂CO₃가 석출제로서 효과가 우수했다. 또한 용액에 아세톤이나 에탄올을 첨가하면 리튬(I)의 석출률이 증가했다. 특히 (NH₄)₂CO₃을 석출제로 첨가한 조건에서 용액의 pH가 12까지 증가함에 따라 리튬(I)의 석출률도 증가했다. 동일한 석출조건에서 Na₂CO₃에 의한 리튬(I)의 석출률이 (NH₄)₂CO₃보다 더 높았다.
