Global demand for lithium, cobalt, nickel, and aluminum is climbing as battery manufacturing scales up, but extracting and processing these materials still carries a real environmental cost.1 In Chile's Atacama Desert, conventional lithium extraction from brine has relied on evaporation ponds that draw heavily on freshwater resources in one of the driest regions on Earth, a practice that has drawn scrutiny for its effects on local water tables and the communities that depend on them.1,4
A newly launched German-Chilean initiative, PaNaBat, is attempting to solve these issues.1,2

What is the PaNaBat Initiative?
Launched in February 2026, PaNaBat, the German-Chilean Partnership for Research on Sustainable Battery Raw Materials is designed to connect research institutions, companies, and cooperation partners in Germany and Chile to help strengthen research collaboration, education, technology transfer, and industrial cooperation around sustainable battery raw materials, lithium extraction, and battery recycling.1,2
The project's first phase will run from February 2026 to January 2029 and is coordinated by the Fraunhofer Institute for Silicate Research (Fraunhofer ISC) in Würzburg, with €450,000 in funding from the German Federal Ministry of Research, Technology and Space.3
Research partners include:2,3
- Universidad Católica del Norte
- Fraunhofer Chile
- The Institute for Surface Engineering and Thin Films (IST)
- The Institute for Solar Energy Systems (ISE)
Why Chile Matters
More than half of the world's known lithium reserves sit within the so-called lithium triangle spanning Chile, Bolivia and Argentina.7
Chile's share of that resource is concentrated in brine deposits beneath the Salar de Atacama, where lithium-rich brine has been pumped and evaporated commercially for decades.1 That scale of extraction has made the region a focal point for concerns about freshwater consumption, brine and groundwater drawdown, and the knock-on effects for local ecosystems and communities that rely on the same water resources.1,4
PaNaBat frames Chile as a lithium source and a place where lower-impact extraction methods need to be developed and tested under local hydrogeological conditions rather than imported wholesale from elsewhere.1
The Technology Agenda
Extraction
PaNaBat's stated research interests include direct lithium extraction (DLE) and closed-loop evaporation processes, both aimed at extracting lithium more efficiently in terms of resource and energy use than conventional evaporation-pond methods.1
Direct lithium extraction remains an active area of research; independent reviews note that while DLE can reduce land use and processing time relative to evaporation ponds, it often requires more fresh water at the extraction stage itself, so its overall environmental advantage depends heavily on process design and local water availability.4
Recycling
The agenda covers automated battery dismantling, new sorting technologies, and efficient material recovery.1,2
One detail that distinguishes PaNaBat's approach is its focus on recovering battery materials while preserving their functional properties, rather than breaking every spent battery down into elemental raw materials for reprocessing.1 This mirrors a wider research trend often described as direct recycling, where cathode materials are restored or upgraded for reuse in new battery production rather than dissolved and rebuilt from scratch, an approach that can shorten the recycling pathway and reduce cost and energy demand relative to conventional pyrometallurgical or hydrometallurgical recycling.6
PaNaBat's scope extends beyond lithium mining to a wider circular system covering lithium, cobalt, nickel and aluminum.1,2 Its recycling agenda specifically includes closed material loops and lower-carbon recycling processes for these materials, positioning battery-materials recovery as a way to reduce reliance on newly mined critical raw materials over time.2
The project's stated strategic objective is to help build a foundation for a more sustainable circular economy in the European battery market, connecting Chilean raw-material supply with German processing, recycling and manufacturing expertise.2, 3

Measuring Environmental Impact
To assess whether these approaches actually reduce environmental burden, PaNaBat plans to draw on established environmental-assessment methods, namely life cycle analysis (LCA), life cycle engineering (LCE) and Integrated Computational Life Cycle Engineering (ICLCE).3
ICLCE, developed in earlier work on traction batteries, was designed to make life cycle modeling of complex battery systems faster and more comprehensive by linking detailed process data with variable background and regional contexts, rather than relying on simplified, one-off assessments.5 Applying this kind of framework earlier in technology development is intended to let researchers compare extraction and recycling routes on a more consistent environmental basis before those routes are scaled up commercially.3
What Happens Next?
PaNaBat is currently in its setup phase, during which initial pilot projects are being launched to test and refine the platform itself and its organizational structure; further collaborations with external partners are planned.
The project is also supported by an industry advisory board made up of German and Chilean companies, predominantly small and medium-sized enterprises, which are expected to contribute as the project moves forward.1,3
For now, PaNaBat represents a set of research objectives and a collaboration structure rather than a demonstrated commercial outcome.
Whether direct lithium extraction, closed-loop evaporation, functional-material recovery, and life cycle-based design tools can meaningfully lower the resource and environmental burden of battery materials across both the extraction and recycling ends of the chain is the question the project has set out to answer, not one it has yet resolved.1,2,3
