Highly selective and efficient extraction of lithium from brine is considered a promising strategy to alleviate the imbalance between supply demand resources. However, it still challenging for ions (Li+) recovery brine. In this work, LiMn2O4 nanoparticles embedded in situ carbon networks (LMO-C) derived metal–organic frameworks by incomplete calcination have been developed via hybrid capacitive deionization (HCDI) process. The adsorption capacity obtained LMO-C Li+ 3.5 mmol g–1, while separation factor reaches 24.5 at high Mg:Li ratio 20. insertion Li atoms lattice were visually confirmed. addition, found that synergistic effect LMO retained surface LMO-C, above effectively promotes migration sustainability HCDI This work believed provide guidance design synthesis high-performance materials practical

Materials Horizons, Journal Year: 2024, Volume and Issue: 11(21), P. 5209 - 5219

Published: Jan. 1, 2024

With the gradually increasing requirement for freshwater, capacitive deionization (CDI) as a burgeoning desalination technique has gained wide attention owing to its merits of easy operation, high efficiency, and environmental friendliness. To enhance performance CDI, different CDI architectures are designed, such membrane hybrid flow-electrode CDI. However, these systems have their own drawbacks, cost membranes, capacity limitation carbon materials slurry blockage, which severely limit practical application. Notably, rocking-chair (RCDI) composed symmetric electrode delivers excellent because special dual chamber structure, can not only break through limitations materials, but also deliver continuous process. Although RCDI showcases promise efficient desalination, few works systematically summarize advantages applications in field. This review offers thorough analysis RCDI, focusing on structure designs applications. Furthermore, performances other compared demonstrate prospect is elucidated.
