AI Technical Summary
Existing technologies struggle to efficiently and selectively extract lithium from shale gas wastewater with low energy consumption, and traditional methods suffer from insufficient stability and selectivity of lithium manganese oxide materials.
A spinel-type lithium manganese oxide material (LMO-Al-F) modified with aluminum fluorine co-doping was used as a lithium-ion sieve electrode. It was prepared by solid-state sintering and applied to a rocking-chair capacitor deionization system to achieve selective insertion and release of lithium ions.
It improves lithium selectivity and adsorption capacity, reduces energy consumption, and enhances the material's cycle stability and lithium selectivity, making it suitable for rapid and efficient lithium extraction in complex ionic matrices.
