Abstract: Lithium is an important strategic resource. With the rapid development of new energy industry in recent years, the demand for lithium metal and its compounds has increased rapidly. Most of our proved lithium resources were distributed in salt lake brine, but the high magnesia lithium ratio restricted the large-scale development and utilization. Among the many methods of lithium extraction, lithium ion sieve adsorption technology has been widely studied because of its simple process, high selectivity and recyclability. However, the artificially prepared lithium ion sieve is mostly in powder form, difficult to recover and reuse, which is not conducive to popularization and application. By forming technologies such as granulation and casting film, lithium ion screen can be constructed as macro-size adsorbent, which can effectively make up for its deficiency in practical application, and has great significance for accelerating the development of salt lake brined lithium resources and realizing the self-sufficiency of Chinese lithium resources. In this paper, the main types and development status of lithium ion screen, the common preparation methods of macroscopic large size lithium ion screen, and the application progress of macroscopic large size lithium ion screen in adsorption and extraction of lithium are reviewed. Finally, the technology is summarized and prospected.
