摘要：Lithium–aluminum layered double hydroxides (Li/Al-LDHs) were first industrialized successfully as Li+ adsorbents in lithium resource extraction from salt lakes due to the unique advantages of acid-free desorption without dissolution loss. This chapter offers a comprehensive review of the research and application progress related to Li/Al-LDH adsorbents. The structural properties of Li/Al-LDHs and the underlying mechanism of acid-free lithium extraction are introduced in detail. Furthermore, the quantitative influence of desorption intensity and the regeneration method are elucidated, which are of great significance for the long-term cycle stability of Li/Al-LDHs. Synthesis methods for Li/Al-LDH powders and diverse molding technologies, which are indispensable for industrial applications of Li/Al-LDHs, are systematically summarized. Addressing the challenges in the production and application of Li/Al-LDHs, starting from the structural properties and the adsorption/desorption mechanism, the current innovative modification strategies and optimization processes for continuous lithium extraction are listed, offering labor-saving directions for lithium extraction enhancement from brines. Furthermore, optimized Li+ adsorption processes and performances of Li/Al-LDHs in different types of low-grade brines are comprehensively introduced. Finally, the chapter anticipates potential development trends for Li/Al-LDHs, providing novel perspectives on the advancement of functional Li/Al-LDHs in Li+ adsorption and the comprehensive extraction and utilization of brine resources. ?
