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.

LISA, standing for “LIthium sulphur for SAfe road electrification”, a 43-months research and development project, has been granted 7.9M€ by the European Union’s Horizon 2020 research and innovation program . The main goal of LISA is to develop an innovative Lithium chemistry with hybrid solid state electrolytes (SSEs) validated according to UN38.3 and EUCAR standards and ready for integration in automotive battery packs. The project directly builds on the results of the ALISE project ( in which more than hundred pouch cells (290 Wh/kg, 240 Wh/L, 12.5 Ah) have been produced, and a first module for PHEV has been built containing 82 Lithium Sulphur cells. LISA aims to reach new performance levels of 450 Wh/kg and 700 Wh/L at costs < 70 € k/Wh at cell level positioning LiS technology in-line with EU SET Plan Action 7 targets on batteries for e-mobility. Moreover, with Renault and VDL Group on-board, prominent European OEMs for BEVs and e-bus, the technology will not only be developed and evaluated for light duty vehicles (LDVs), but also for medium duty transport applications (i.e. e-bus) with the main focus on fully electric drivetrains, i.e. BEVs. 

The LISA consortium covers the full battery value chain for electromobility and includes raw material suppliers, component manufacturers, cell manufacturers, integrators, OEMs and a recycling company. The consortium has a balanced profile of 2 universities (Cranfield University, Technische Universität Dresden), 3 RTOs (Leitat, Fraunhofer IWS, CIC Energigune), 4 SMEs (OXIS Energy, Pulsedeon, Accurec, Optimat) and 4 large enterprises (Varta Micro Battery, Arkema, VDL, Renault), and includes the only European LiS cell manufacturer with commercially operating production plant (OXIS Energy). In LISA, Accurec will develop and demonstrate an efficient Li-S battery recycling process in respect of energy consumption, cost and recycling efficiency. To achieve the target, key technologies including low-temperature (e.g. cryogenic) pre-treatment, mechanical separation and hydrometallurgical treatment for lithium recovery are proposed and will be validated. Additionally, Accurec will support the environmental and economical assessment for the Li-S technology.

NAIMA: New Na-ion cells to accelerate the European Energy Transition
The European project NAIMA aims to develop a new generation of high-competitive and safe Na-ion cells for the current and future energy storage technologies, supported by the key actors of the European Battery value chain

The new EU-funded project NAIMA “Na Ion materials as essential components to manufacture robust battery cells for non-automotive applications” was kickstarted in December 2019 in Amiens (France). This project was awarded a Horizon2020 programme grant of almost 8 M€ by the European Commission. The duration of the project will be 36 months.
The NAIMA project will demonstrate that two new generations of highly-competitive and safe Na-ion cells developed and tested during the project are some of the most robust and cost-effective alternatives to unseat current and future Li-based technologies in dedicated storage applications, nowadays controlled by Asian industry. The Na-ion disruptive technology is already supported by a solid European Battery value chain (industry partners of the consortium) through their solid commitment of substantial investments in the manufacturing of all components of a battery, preserving the ownership and industry strength around European countries.
The project consortium is composed of 15 partners from 8 European countries, and is led by the French company TIAMAT, which is specialized in the design, development and manufacture of sodium ion battery cells targeting fast charging, high discharge current applications in mobility  and stationary storage sectors.
Accurec participates the project as a partner and is responsible to develop a sustainable and cost efficient recycling process for Na-Ion batteries.

The new EU-funded project ECO2LIB “Ecologically and Economically viable Production and Recycling of Lithium-Ion Batteries” launched in January 2020.

The ECO2LIB project is successor of Sintbat project, which managed to develop a cheap and energy efficient, maintenance free, lithium-ion based energy storage system. The ECO2LIB project adds to the successes of the Sintbat project, shifting focus to a new key performance improvement (KPI), the cycle related costs per energy: €/kWh/cycle. It very well reflects the real need of the customers if a minimum volumetric energy density is added. An extended LCA, cradle-to-grave will also be setup to judge the environmental impact of the different options and to choose the best. In fact, the ECO2LIB acronym was created to underscore the ecological and economical importance of the project.
ECO2LIB brings together a strong and complementary consortium, including 10 partners from 6 European countries. The project is led by VARTA MICROBATTERY Germany, and completed by international experienced scientific institutes and OEM`s.
Within the project, ACCUREC will lead the work package for recycling and the investigation of an innovative recycling route, with higher material efficiency and cost effectiveness.

Having started in January 2021, the Horizon 2020 project LOLABAT „LOng LAsting BATtery System“ funded by the European Union has been developing rechargeable nickel-zinc batteries (RNZB), which show enormous potential for the European martket, especially for stationary energy applications. The battery system is characterised by a high energy or power density, the absence of critical and toxic ingredients while keeping production costs low. With 17 partners from 7 European countries, the scientifically competent and economically oriented consortium covers the entire value chain from raw material to production to end-of-life and allows a detailed analysis of second use and recycling strategies.

By focusing on the ecological consideration of the entire life cycle, the investigation of possible recycling technologies led by Accurec has a key position in the project. The work, which will begin next month, will compare, among other things, safe wet crushing of the batteries with consecutive hydrometallurgical treatment of the active masses to the best available technique of vacuum distillation developed and operated industrially by Accurec. For the evaluation of the different processes, the revision of the European Battery Directive will also be taken into account.
