ION SIEVES USED IN LITHIUM RECOVERY (Mn and Ti Oxides)

Özet

The growing global demand for lithium, driven by its critical role in battery technologies, has intensified research into efficient and sustainable recovery methods. Among these, lithium-ion sieves (LIS) based on manganese (Mn) and titanium (Ti) oxides have emerged as promising candidates due to their high selectivity, low energy requirements, and environmental compatibility. This study reviews the synthesis methods, structural characteristics, and adsorption mechanisms of MnO₂- and TiO₂-based ion sieves, evaluating their performance in lithium recovery from aqueous media. The advantages and limitations of various synthesis techniques, including solid-state, hydrothermal, sol-gel, and precipitation methods, are discussed in detail. Furthermore, recent developments in composite materials, doping strategies, and surface modifications are highlighted to improve stability and lithium retention capacity. Future perspectives are also addressed, emphasizing the integration of artificial intelligence (AI) and Internet of Things (IoT) technologies to optimize adsorbent design and process efficiency. The findings suggest that with continued innovation in materials engineering and process integration, LIS technologies could play a pivotal role in the sustainable extraction of lithium from both conventional and low-grade sources.
