Problem
Traditional lithium extraction methods, such as evaporative processes, suffer from low lithium recovery rates and significant environmental impact. Many Direct Lithium Extraction (DLE) technologies face challenges related to short sorbent lifespans, slow reaction times, and low selectivity, hindering their economic viability and scalability.
Solution
ExSorbtion provides a Direct Lithium Extraction (DLE) solution utilizing proprietary, high-selectivity manganese-based sorbents with a lifespan exceeding 500 cycles. The technology achieves rapid lithium adsorption and regeneration in under 5 minutes, enabling efficient lithium recovery from brines, even at low concentrations (as low as 40 mg/L). ExSorbtion's patented regeneration process uses carbon dioxide gas instead of acid, resulting in a carbon-negative process with minimal water usage and lower operating costs. The DLE process directly produces high-value lithium carbonate, eliminating the need for additional conversion steps.
Target Audience
ExSorbtion's primary customers are lithium producers, battery manufacturers, and companies in the electric vehicle (EV) supply chain seeking a cost-effective and environmentally sustainable lithium extraction solution.
