The rising demand for electric vehicles (EVs) has emphasised the necessity for effective and eco-friendly approaches to lithium recovery. Extracting lithium by the conventional evaporation method not only requires a lot of time (12 to 18 months) but also poses notable environmental concerns, including high carbon, water, and land footprints. Direct Lithium Extraction (DLE) is a modern potential alternative for directly extracting lithium from aqueous resources with minimal environmental consequences. Among the various DLE techniques, membranes have substantial potential to extract lithium ions due to their advantageous characteristics, such as selective separation, high efficiency, and ease of use in continuous processes. The main objective of my project is to create novel titanium-based composite membranes for selective lithium recovery from brines. For this purpose, titanium-based adsorbents with high selectivity towards lithium will first be designed to be further incorporated into the membrane matrix for enhanced lithium separation processes. The expected outcomes include the development of highly selective and durable titanium-based composite membranes capable of efficiently separating lithium from brines.
