Abstract: Disclosed is a method for manufacturing lithium hydroxide from a lithium-ion battery waste. The method includes heat-treating the cathode scraps as the lithium-ion battery waste under an NH3 gas atmosphere to convert lithium incorporated in the cathode scraps into lithium oxide (Li2O) or lithium hydroxide (LiOH). The lithium is then leached using water, followed by solid/liquid separation to remove solid residues. CaO is added to the filtered leached solution to precipitate impurities, which are removed before passing the solution through ion exchange resin. After evaporation, crystallization is achieved either by adding isopropyl alcohol or using an evaporative crystallizer, yielding high-purity LiOH·H2O crystals. This process offers an efficient recycling method for lithium-ion batteries with high lithium recovery and purity.
