摘要：Lithium demand is surging to support the global energy transition, raising concerns over the environmental impacts of its production. However, the quantitative contribution of advanced extraction technologies in reducing the environmental impacts of lithium is still unclear. To fill this gap, this study first conducts a comprehensive life cycle assessment (LCA) of 11 environmental impact categories from lithium extraction worldwide, covering diverse sources (brines, spodumene, clays, and geothermal brines) and extraction technologies. Results reveal that producing 1 kg of Li2CO3 generates 2.14-19.11 kg CO2-eq, where the Mg2+/Li+ ratio in brines is a key driver of environmental outcomes, influencing extraction efficiency. We further evaluate emerging Direct Lithium Extraction (DLE) technologies for low-concentration, high Mg2+/Li+ brines, finding that most DLE methods yield similar to 4-fold higher impacts than traditional methods due to intensive chemical and energy use. In contrast, four advanced DLE technologies, including adsorption-coupled membrane, solvent extraction, and electrochemical deintercalation/intercalation with LFP/FP or LiMn2O4/lambda-MnO2 electrodes, reduce emissions by up to 60% relative to other DLE options. Transitioning to renewable energy enhances DLE viability, potentially lowering impacts below traditional levels. Our findings highlight pathways for sustainable lithium supply through technological advancement and energy decarbonization.
