Electrochemical Direct Lithium Extraction: A Review of Electrodialysis and Capacitive Deionization Technologies

Resources, Journal Year: 2025, Volume and Issue: 14(2), P. 27 - 27

Published: Feb. 3, 2025

The rapid expansion of lithium-ion battery (LIB) markets for electric vehicles and renewable energy storage has exponentially increased lithium demand, driving research into sustainable extraction methods. Traditional recovery from brine using evaporation ponds is resource intensive, consuming vast amounts water causing severe environmental issues. In response, Direct Lithium Extraction (DLE) technologies have emerged as more efficient, eco-friendly alternatives. This review explores two promising electrochemical DLE methods: Electrodialysis (ED) Capacitive Deionization (CDI). ED employs ion-exchange membranes (IEMs), such cation exchange membranes, to selectively transport ions sources like seawater achieves high rates. IEMs utilize chemical structural properties enhance the selectivity Li+ over competing Mg2+ Na+. However, faces challenges consumption, membrane fouling, reduced efficiency in ion-rich solutions. CDI uses electrostatic forces adsorb onto electrodes, offering low consumption adaptability varying concentrations. Advanced variants, Membrane (MCDI) Flow (FCDI), ion enable continuous operation. MCDI incorporates reduce co-ion interference effects, while FCDI utilizes liquid electrodes scalability operational flexibility. Advancements electrode materials remain crucial efficiency. Validating these methods at pilot scale assessing performance, scalability, economic feasibility under real-world conditions. Future should focus on reducing costs, developing durable selective creating integrated systems overall By addressing challenges, can provide solutions management, minimize impact, support a low-carbon future.
