The rapid market growth in recent years for eco-friendly electric vehicles and more generally, energy storage technologies, has led to an increase in demand for lithium which is a major raw material for lithium secondary batteries. The technology for producing lithium ions from lithium carbonate in seawater 25 L has been developed, but there are about 60 kinds of various ionic components, which is a difficult process, and only about 4 mg of lithium is recovered. In order to meet the demand of lithium, research is being actively conducted to recycle lithium secondary batteries that contain lithium and can be recycled as a circulating resource, but there is little research on recycling of waste liquid generated during the manufacturing process of lithium secondary batteries. Wastewater of lithium is thought to be able to efficiently concentrate lithium metal during recycling using an environmentally friendly electrodialysis water treatment process. In this study, lithium was concentrated using the electrodialysis of wastewater generated during the production of lithium-ion batteries. The efficiency of the electrodialysis varied according to the applied voltage and the volume ratio of the solution. However, due to the disadvantages of employing limited current densities, optimum conditions for the process needed to be selected. Therefore, the concentration efficiency of lithium was confirmed according to the process conditions, and optimum process conditions were derived. Lithium concentrated at the optimum conditions secured a concentration increase of about 128% compared to the initial concentration of wastewater.
