Inherited Nitrogen Distribution Control in Covalent Organic Framework Cathodes for Efficient Electrochemical Lithium Recovery via Capacitive Deionization.

ABSTRACT: The economic recovery of lithium from brine generated by desalination plants presents a promising pathway toward achieving a sustainable water desalination economy. Selectively recovering Li⁺ ions from brine is challenging due to the presence of other dominant ions. While electrochemical separation techniques, such as hybrid capacitive deionization (HCDI), offer several advantages, success largely depends on developing suitable cathodes currently limited to inorganic materials with notable constraints. Herein, the potential of controlling heteroatom distribution within 2D covalent organic frameworks (2D-COFs) is explored for electrochemical lithium recovery. This marks the first exploration of COF cathodes for lithium extraction via HCDI. By carefully modulating the density of h
