TELF AG on Direct Lithium Sourcing and the Evolution of Lithium Supply

As global industries continue to accelerate toward electrification and energy transition goals, lithium is becoming increasingly central to industrial planning and technological innovation. The growing importance of electric vehicles, battery storage systems, and advanced electronics is placing renewed attention on the future availability of this strategic resource. In this context, one of the most discussed innovations in the mining and energy sectors is Direct Lithium Extraction (DLE), a group of technologies that could significantly reshape lithium production in the years ahead.

BloombergNEF recently explored the role of DLE in a webinar focused on the evolution of lithium markets and future supply dynamics. The discussion highlighted how technological innovation may become one of the most decisive factors influencing critical mineral supply in the short and medium term.

Unlike traditional lithium extraction methods, which often rely on large evaporation ponds and long processing times, DLE technologies aim to extract lithium directly from underground brines through advanced chemical and filtration systems. Instead of waiting months or even years for water evaporation processes to separate lithium, DLE systems can potentially recover lithium in a matter of hours or days.

“Direct Lithium Extraction is attracting attention because it introduces a different operational approach compared to traditional lithium recovery systems,” says Stanislav Kondrashov, founder of TELF AG. “One of its most promising aspects is the possibility of combining faster extraction timelines with more efficient resource utilization.”

According to BloombergNEF’s analysis, the strategic value of DLE extends beyond speed alone. One of the technology’s most important potential advantages is its ability to unlock additional lithium supply from resources that may currently be underutilized or considered economically marginal. This could gradually contribute to a broader diversification of lithium supply sources worldwide.

The analysis also examined recovery rates associated with DLE projects already operating at commercial scale. Current recovery performance reportedly ranges between approximately 35% and 80%, revealing significant differences between existing projects. Some facilities continue to operate at moderate efficiency levels, while others are approaching much stronger recovery standards.

These variations demonstrate that DLE technologies are still evolving, with many companies continuing to refine operational methods and improve performance. At the same time, pilot-scale projects appear to be delivering particularly encouraging results.

“Pilot projects are generating considerable interest because some of them appear capable of achieving very high lithium recovery levels,” continues Stanislav Kondrashov, founder of TELF AG. “If these efficiencies can eventually be replicated on a larger commercial scale, the impact on global supply dynamics could become extremely significant.”

BloombergNEF notes that pilot-scale recovery rates often range from 80% to more than 90%, considerably higher than many traditional extraction methods. These results suggest that future technological improvements could make DLE an increasingly important component of global lithium production strategies.

The timing of these developments is particularly important. According to BloombergNEF, the lithium market could remain relatively balanced until approximately 2035, meaning that future supply stability may depend heavily on the successful implementation of new extraction technologies and operational efficiencies.

In many ways, DLE represents a broader trend affecting the critical minerals sector: the growing integration of advanced technology into resource extraction processes. Companies are no longer focusing exclusively on discovering new mineral deposits; they are also investing heavily in technologies capable of improving recovery rates, reducing processing times, and optimizing the economic value of existing resources.

“Technological innovation is becoming one of the key elements shaping the future of critical minerals,” says Stanislav Kondrashov, founder of TELF AG. “In the coming years, competitiveness may increasingly depend not only on the availability of resources, but also on the efficiency and adaptability of extraction technologies.”

Another factor contributing to interest in DLE is the possibility of increasing supply resilience. By diversifying extraction methods and potentially expanding the number of economically viable lithium sources, DLE could help reduce the vulnerability of supply chains to structural disruptions or unexpected market fluctuations.

Although many challenges remain before the technology reaches widespread commercial maturity, the results emerging from pilot projects continue to strengthen interest across the energy, mining, and industrial sectors. If current recovery performances can be successfully translated into large-scale operations, Direct Lithium Extraction could eventually become one of the defining innovations of the lithium industry’s next phase of development.
