Abstract [en]

The need for lithium hydroxide (LiOH) is increasing with the production of lithium-ion cells. The conversion of lithium carbonate (Li2CO3) to LiOH is an important step to recycle Li-ion cells. The foundation for this project was an EAF (Electric Arc Furnace) dust that had been collected from pyrometallurgical recycling of lithium-ion batteries. Using precipitation with slaked lime (Ca(OH)2), Lithium hydroxide could be refined from the EAF dust. The precipitation process showed a good separation of lithium (Li) from other metals like cobalt (Co), manganese (Mn), nickel (Ni), iron (Fe), magnesium (Mg) and copper (Cu). At the cost of reduced recovery, the final lithium hydroxide concentration could be enhanced by increasing the initial addition of EAF dust. The purity of the final products however needs to be improved to reach the standard for battery production. Overall, the process is promising but needs more testing.

Abstract [sv]

Efterfrågan på litiumhydroxid (LiOH) har ökat med produktionen av litium-jonbatterier. Konvertering av litiumkarbonat (Li2CO3) till LiOH är ett viktigt steg för att återvinna li-jon batterier. Grunden för detta projekt var ett EAF pulver som hade producerats från pyro-metallurgisk återvinning av litium-jon batterier. Med hjälp av utfällning med släckt kalk (Ca(OH)2) kunde litiumhydroxid utvinnas från koncentratet. Processen hade en bra separation av litium (Li) från andra metaller så som kobolt (Co), mangan (Mn), nickel (Ni), järn (Fe), magnesium (Mg) och koppar (Cu). På bekostnad av utbytet kunde den slutliga koncentrationen av litiumhydroxid ökas med en större tillsats av EAF pulvret. Renheten hos den slutgiltiga produkten måste dock förbättras för att nå standarden till batteriproduktion. I helhet är processen lovande men behöver mer testning.
