Ecofriendly, Highly Selective Lithium Extraction by Redox-Mediated Electrodialysis
The rapid proliferation of lithium battery applications has underscored the critical role of lithium supply in the transition to industrial electrification. Existing lithium production methods encounter significant challenges in efficiency, scalability, environmental impact, and cost. The integration of redox-mediated electrodialysis with a dense ceramic Li6/16Sr7/16Ta3/4Hf1/4O3 perovskite membrane, distinguished by its unique lattice structure allowing only lithium-ion exchange and transport, enables efficient, highly lithium-selective extraction directly from a diversity of resources including seawater and various brines. This approach offers continuous operation capability, can utilize renewable power, and has notable advantages, including chemical-free operation and little waste generation. Overall, this innovative solution presents a one-step, ecofriendly, highly selective lithium extraction method.
The one-step redox-mediated electrodialysis (rm-ED) strategy for direct lithium extraction from brines with LSTH membrane is employed for high selectivity powered by solar panels.
期刊介绍：
ACS Central Science publishes significant primary reports on research in chemistry and allied fields where chemical approaches are pivotal. As the first fully open-access journal by the American Chemical Society, it covers compelling and important contributions to the broad chemistry and scientific community. "Central science," a term popularized nearly 40 years ago, emphasizes chemistry's central role in connecting physical and life sciences, and fundamental sciences with applied disciplines like medicine and engineering. The journal focuses on exceptional quality articles, addressing advances in fundamental chemistry and interdisciplinary research.
