CloseWEEE is an european research project, aiming to increase the range and yields of recovery materials from WEEE streams. Accurec’s work is devoted to recycling-actions of waste Li-Ion batteries from notebooks, mobile phones, smartphones and tablet PCs by evaluating the recycling potential of Cu, Co, Li and graphite. By analyzing TRLs of new recycling technologies and the market situation, latest knowledge will be integrated to construct and test an innovative microwave based process technology for recycling of critical materials with a high rate of yield.

HELIS is an EU-funded research project working on one of viable post Li-ion battery can-didates: lithium sulfur battery. A strong consortium has been formed, including renowned universities and institutes (The National Institute of Chemistry (NIC), Max Planck Ins-titute (MPI), the Centre National de la Recherche Scientifique (CNRS), Chalmers Univer-sity of Technology (Chalmers), Tel Aviv University (TAU), Westfaelische Wilhelms-Uni-versitaet Muenster, (WWU), public funded technology transfer institutions (Fraunhofer, INERIS, IREC), SMEs (Picosun, Solvionic, Accurec), and two large enterprises (SAFT and PSA). With a solid foundation from the development in former FP7 project EUROLIS, HE-LIS project is aiming to double the energy density and specific power compared to cur-rent Li-ion batteries while while maintaining the low cost of Li-S cells; to obtain a dura-bility according to automotive industry specifications; to scale-up and engineer materials and components; to understand the ageing of Li-S cell prototypes; to fully assess Li-S cells through several safety tests according to the most current European directives.
Accurec is contributing in the project by developing a safe and effective recycling solution for the Li-S batteries. Moreover, Accurec will support the environmental and economical assessment for the Li-S technology.

ZnMobil is a research project funded by German Federal Ministry for Economic Affairs and Energy, aiming to develop a scalable zinc-air battery for mobile applications that can be rechar-ged both electrically and mechanically, i.e. by replacing the electrolyte. A mechanically rechar-geable battery offers the advantage of very short charging times, while electrical rechargeable battery places significantly lower demands on the necessary infrastructure, but requires longer charging times. A battery system with both functionalities therefore offers the greatest customer benefit. In the course of the project, all core components of the new zinc-air battery will be processed. A suspension of Zn particles in alkaline electrolytes (Zn slurry), whose composition is optimized with regard to high discharge currents and storage stability, is to be used as zinc electrode. Gas diffusion electrodes (GDE) for oxygen reduction reaction (ORR) and for oxygen development (SEE oxygen development electrodes) as well as bi-functional gas diffusion elec-trodes are systematically further developed and electrochemically characterized. The results obtained are combined in a multi-cell structure and tested together. Finally, the results are used as the basis for initial analyses of the economic efficiency of corresponding automotive battery systems.
The consortium consists of Covestro Deutschland AG, Grillo Werke AG, Varta Microbattery GmbH, Zentrum für Brennstoffzellentechnik GmbH, TU Freiberg, Universität Duisburg-Essen, Universität Hannover and Accurec. The partners have many years of experience and know- how in battery technology, fuel cells and electrolysis as well as materials science, zinc produc-tion and recycling. With the well-established and many-year-experienced Vacuum Distillation Technology, Accurec contributes in the development of an efficient recycling solution for the degraded Zn slurry, in order to fully recover the zinc as high purity product to re-integrate it directly in Zn powder production process (Closed-loop approach).

DEMOBASE, an EU founded project lunched in October 2017, aims to cut down development and testing efforts for e-drivetrains at least by a factor 2 and to improve their efficiency by 20%. Several improvements and concepts from cell level to vehicle level are introduced into the project in order to achieve the high safety standard and increase the production efficiency. R&D activities from 11 partners will be carried out for an urban prototype vehicle which will be demonstrated at the end of the project.
Accurec’s contribution within the DEMOBASE project is devoting to recycling-actions of End- of-life traction battery packs. Safety risks of End-of-life traction batteries in waste stream, namely during transportation, dismantling, cell recycling process, are studied to ensure the highest safety standard. Moreover, Accurec investigates on the state of the art Li-ion batteryrecycling processes and develops a recycling simulation tools which calculate the theoreticalrecycling efficiency with considering the process cost, environmental impact and safety. Accu-rec participates also in the automotive battery pack design phase by giving recommendations from recycler point of view.

CROCODILE is a 12Mio€ EU-funded project, launched 1st of June 2018, focusing develop-ment of innovative metallurgical systems based on advanced pyro-, hydro-, bio-, ionic- and electrometallurgy technologies for the recovery of cobalt from a wide range of primary and secondary European resources. CROCODILE brings together 24 participants, medium sized specialized companies but also global players like Glencore, Freeport or Stena as well as public institutions to demonstrate the synergetic approaches along the value chain of Cobalt.
First of all, secondary sources of Cobalt – like batteries, WEEE, alloys, catalysts etc. – are identi-fied, investigated and collected exemplary. In a relevant scale, they are pretreated and concen-trated by different participants and physical technologies, before the cobalt is extracted from intermediate product by an innovative mobile hydrometallurgical deep-eutectic solvent. Primary laterite concentrates are feeded to a newly developed bio-leaching system. Both streams are then forwarded to different electro winning processes, which target an improved yield and cost optimization. The concerted treatment activities approach a better reintegration of secondary Co-sources, higher efficiency in Co extraction from primary ores, flexible intermediate treatment and concentration processes as well improvement refining processes, to reduce significantly the potential supply risk of Co for the European industry in future.
