What will happen in the future to used batteries from electric vehicles? How can their valuable materials be recycled efficiently to create a genuine cycle for lithium-based batteries? With its research and development activities, the Fraunhofer R&D Center for Electromobility (FZEB) is conducting research and development into efficient and sustainable solutions for battery recycling in Germany. Now, another joint project by battery researchers and industry has been launched for the direct recycling of battery materials: ProBatman, which aims to optimize the process steps along the entire recycling process chain in terms of purity and yield.

To reduce dependence on rising electricity prices, German households are in-creasingly turning to stationary battery storage systems combined with photo-voltaic systems. These systems provide solar energy around the clock, relieving the burden on power grids. But what happens in ten to fifteen years when these storage systems reach the end of their service life? The answer is direct recycling.

From February 3 to 5, 2026, the 2nd Conference on Battery Direct Recycling brought together international experts from research, industry, and politics at the Congress Centrum Würzburg. The event, organized for the second time by the Fraunhofer Institute for Silicate Research ISC, demonstrated how the field of research into the direct recycling of battery materials has developed in just one and a half years.

Sustainable and high-quality conductive additives for lithium-ion batteries are one of the keys to e-mobility in Europe. In view of the increasing demand for rechargeable batteries due to the transition to electric vehicles and renewable energies, the development of innovative and environmentally friendly materials is of central importance. The HiQ-CARB joint project, funded by the European Union/EIT RawMaterials, has taken a major step forward in this key technology for reducing CO2 emissions over the last four years.

The electric vehicle market is booming and plays a crucial role in our global climate goals. However, with this growth comes an increase in the number of consumed batteries that contain valuable raw materials. Unfortunately, there are currently no truly efficient and energy-saving recycling technologies available . The "ProBatman" project aims to address this issue by optimizing recycling processes and developing new technologies to improve the quality and yield of battery recycling.

Solid-state batteries (SSBs) are considered the next generation of batteries com-pared to conventional Li-ion batteries. Despite significant research efforts, very few SSBs are market-ready. In recent years, various promising materials have been introduced, but one of the main challenges persists: the combination of these materials into a stable cell. The project consortium of FUNCY-SSB (pro-nounced "funky-ssb") with partners from Germany, Slovenia, and Norway aims to change this over the next three years.

After approximately three years, the battery project IDcycLIB, funded by the German Federal Ministry of Education and Research (BMBF) with around 7 million euros, has successfully concluded in December 2024. During the final project meeting at the Fraunhofer Institute for Silicate Research ISC in Würzburg, the outstanding results of the project were presented.

The HiQ-LCA project, funded by EIT RawMaterials and co-funded by the EU, supports the battery industry in complying with the EU Battery Regulation by offering various tools and services, including an advanced Life Cycle Assessment (LCA) database to be developed as a satellite database of the renowned ecoinvent database. To foster collaboration and encourage data contribution, project partner ecoinvent successfully organized industry workshops in 2023 and 2024, bringing together stakeholders to address key challenges and promote transparency. By contributing data, industry leaders gain access to peer-reviewed LCAs, compliance support, and an enhanced role in advancing sustainable battery production.

The aim of the KMU-innovativ project ELEKTRA is to develop a continuous manufacturing process for electrochromic films. To this end, the electrochemical batch process is being further developed into a roll-to-roll (R2R) process for aqueous solutions on film. An automated coating system is being designed that enables in-situ quality control by means of optical layer thickness measurement and segmented anode control. At the same time, the control of the EC films is to be developed. The process quality will be analyzed as part of the prototype implementation. The film elements will be tested in practice by applying them to a glass element as a demonstrator.

The European project SOLIDBAT, funded by the European Union through its Horizon Europe program, aims to develop high-energy solid-state batteries for automotive applications, focusing on sustainability, safety, and scalable production to support climate-neutral transportation.

Without lithium-ion batteries, environmentally friendly mobility and a sustain-able energy supply would be virtually inconceivable. However, the increasing demand for batteries and the associated raw materials poses major challenges. The REWIND project aims to overcome important obstacles on the way to an efficient and ecologically sustainable circular economy. REWIND is part of the BattFutur program of the German Federal Ministry of Education and Research (BMBF).

The ReUse project, short for "Efficient direct recycling for low-value LFP battery for circular and sustainable waste management," is a 36-month research initia-tive. It is funded by the European Union's Horizon Europe research and innova-tion program, operating under Grant Agreement No. 101137774, with a substan-tial EU contribution amounting to €4,927,664.93 in funding. The project com-menced in January 2024.
