| Abstract Scope |
Direct recycling offers distinct advantages compared to pyrometallurgical and hydrometallurgical routes for Li-ion batteries recycling as it allows for the regeneration of battery components directly, without altering their chemical structure. However, there is room for improvement, particularly in the utilization of waste generated by its processes. This study investigated a route to recover lithium from wastewater generated from direct recycling of end-of-life Li-ion batteries. Two steps of electrodialysis, namely Standard Electrodialysis (SED) and Bipolar Membrane Electrodialysis (BPED) were performed to concentrate lithium content and convert it to valuable LiOH product. In addition, preliminary techno-economic and environmental impact analyses show a significant improvement by producing LiOH via electrodialysis, compared to the conventional lithium production via brine extraction. The process was assessed to be beneficial for lithium extraction from secondary resources and enhancing overall battery recycling efforts. |
