Heterostructure‐Engineered Conductive MOFs Coupled with MoSe 2 @MXene Framework for Efficient and Selective Lithium Extraction from Salt Lake Brine via Capacitive Deionization

redox activity and reversible interlayer intercalation. Importantly, density functional theory (DFT) calculations confirm a substantially lower migration barrier for Li⁺ (0.052 eV) compared to competing cations, underpinning the observed selectivity. This work highlights a rational heterostructure design strategy for advancing CDI technology in lithium recovery.
