DuPont launched an end-to-end Direct Lithium Extraction (DLE) portfolio featuring more than 20 products across multiple separation technologies. The new platform is designed to improve lithium recovery, enhance process efficiency, and provide customized solutions for a wide range of lithium brine resources. As global demand for lithium continues to rise due to the rapid growth of electric vehicles (EVs) and energy storage systems, the industry is increasingly adopting DLE as an alternative to traditional hard-rock mining and evaporation-based lithium production.
Comprehensive DLE Portfolio Covers the Full Process
DuPont’s portfolio spans the entire lithium brine treatment process, including extraction, purification, and final concentration. The offering includes lithium-selective sorbents, nanofiltration membranes, reverse osmosis membranes and ion exchange resins. Customers can deploy the complete integrated flowsheet or select individual technologies tailored to their specific brine composition and process requirements.
Customized Solutions for Diverse Brine Resources
A key differentiator of the new portfolio is its breadth and flexibility, which allows DuPont to design customized solutions for a wide range of lithium extraction applications. For example, the portfolio includes DuPont AmberSorb adsorbent technologies for both high-temperature and low-temperature brine streams, enabling efficient lithium recovery from diverse global resources. In addition, DuPont offers multiple grades of FilmTec LiNE nanofiltration and reverse osmosis elements. These products provide specialized separation characteristics and incorporate low salt rejection reverse osmosis (LSRRO) technology to achieve ultra-high lithium concentration.
Integrated Technologies Improve Yield and Purity
DuPont has combined several advanced technologies into a single platform, including: DuPont IntegraTec, Inge, FilmTec and DuPont AmberLite. By integrating these technologies, the company aims to improve lithium yield, purity, and concentration throughout the extraction process while optimizing performance across the entire DLE flowsheet.
DuPont Highlights End-to-End Process Optimization
“DLE processes are highly sensitive to the lithium brine composition, temperature, and competing ions. By integrating the lithium-selective sorbents, membranes, and ion exchange technologies into a single process design framework, we can optimize the full flowsheet rather than treating them in isolation,” said Dr. Martin Deetz, Senior R&D Laureate for DuPont Water Solutions. He added that customers are seeking to move from laboratory testing to reliable lithium production as quickly as possible, and that DuPont’s modeling, testing, and piloting capabilities can accelerate the development of tailored extraction flowsheets.
Global R&D Network Supports Commercial Deployment
Beyond the product portfolio, DuPont is supporting customers through its global research and development network. The company provides advanced laboratory testing, process modelling, piloting support and validation using real brine samples. These services help lithium producers evaluate performance, reduce development risks, and accelerate the transition from initial assessment to commercial implementation.
Growing Demand for Lithium Drives DLE Adoption
As demand for lithium continues to surge, producers are looking for more efficient ways to develop new lithium resources. DLE is gaining traction because it offers a more coordinated and potentially faster approach to lithium recovery compared with conventional extraction methods. DuPont’s integrated platform is intended to help producers improve recovery rates, achieve higher product purity, and scale operations more effectively.
Industry Education and Technical Support
To support industry adoption, DuPont hosted an educational webinar on June 18, 2026. The session explained how tailored DLE technologies can increase lithium yield and purity while addressing the unique characteristics of different brine resources. As per the press release, DuPont also highlighted how customers can use its testing, modeling, and piloting support to evaluate and implement customized direct lithium extraction solutions.
