During the third semester, researchers from KIT further studied and improved the conditions for the mechanochemical transformation of black mass (BM) into metallic black mass (MBM). Since BM supplied by ACC is already in a reduced state, they focused on reducing BM supplied by TES. This BM consists mostly of NMC (lithium nickel manganese cobalt oxides) cathode material and graphite, which was found to slow down the reaction kinetics. The reduction of the cathode active material by the metallic reducing agent result in the formation of the transition metals along with lithium oxide (Li2O) and the oxide of the respective reducing agent, which can be monitored by X-ray diffraction.

In contrast to the previous two semesters, researchers switched from shaker mills to planetary mills, which enable control of the rotation speed and larger volumes that can be processed. Various parameters such as ball-to-sample ratio (BSR), ball size, total load and rotation speed were investigated to optimise for a short reaction time.

Main take-aways

In general, the higher the BSR, the more mechanical energy can be transferred per gram of powder which results in a more intense milling and a faster reaction; however, this limits the throughput. Larger balls, on the one hand, lead to higher kinetic energies. On the other hand, fewer balls are used to keep the BSR constant resulting in a lower collision frequency. The maximum rotation speed is lower to prevent damage to the grinding media.

With Calcium as the reducing agent, no reaction was achieved at all. An unfavorable combination of ductility and size of the calcium pieces seems to resist further size reduction, which is required for the reaction.

Aluminium has the advantage of being used as a current collector and is already present in the black mass. However, during the reaction, LiAlO2 is formed, which is limiting the subsequent Li extraction efficiency in WP5. This problem can be avoided when magnesium is used as the reducing agent, which proved to be more reactive than aluminium but doesn’t form other lithium compounds than Li2O.

Compared to the shaker mill, a higher reaction rate was observed in the planetary mill. Researcher from KIT achieved a complete conversion of the lithium transition metal oxide in the planetary mill within 3 h using Mg as the reducing agent. In a larger version of the mill, the required milling time increases to 8 hours. Here, further investigations are planned for the next months.

Following previous work performed in work package 5, researchers from KIT further investigated the lithium (Li) extraction from black mass (BM) supplied by partners ACCUREC (ACC) and TES.

The BM provided by ACC consists of graphite, as well as transition metals such as nickel (Ni), manganese (Mn), and cobalt (Co), along with their respective oxides and impurities like copper (Cu), iron (Fe) and few fluorinated compounds. Li is present in the form of lithium carbonate (Li2CO3), lithium fluoride (LiF) and lithium aluminium oxide (LiAlO2). However, breaking off lithium aluminium oxide to a soluble Li-salt and removing fluoride contamination proved to be challenging.

Previous work reported the simultaneous incorporation of fluoride ions and decomposition of LiAlO2 using an excess of calcium hydroxide (Ca(OH)2) at elevated temperatures.  More recent developments of the processes show improvement, especially decreasing considerably the amount of of Ca(OH)2 , while achieving a Li extraction of 87 %. Instead of heating the suspension, it is possible to initiate the reaction by liquid-assisted grinding in a planetary mill. The results show LiAlO2 is decomposed. However, the fluoride content is not efficiently removed.

In the BM supplied by the partner TES, most Li is present as lithium transition metal oxides (LiTMO) and a small amount of LiF. To enable Li extraction, this BM was reduced by reactive milling in Task 4.4 – Reactive milling for the production of metallic black mass (MBM). The obtained MBM consists of graphite, the metallic composite, lithium oxide and the oxidised reducing agent, along with some impurities like Fe and fluorinated compounds.

After investigating aluminium (Al) and calcium (Ca) in the previous steps, researchers at KIT performed tests to assess Li extraction using a magnesium (Mg) system, which presents various advantages, namely: avoiding, on one hand, the formation of Li salts with bad solubility, and relying on the other hand on insolubility of Mg in the high pH aqueous solution.

After aqueous extraction, researchers obtained a mixture of Li2CO3 and LiF. In the upcoming months, this mixture will be purified to a battery-grade material.

The Critical Raw Materials Act (CRMA), proposed by the European Commission in March 2023, was adopted by the Council one year later, on 18 March 2024, marking the last step in the decision-making procedure.

Looking back in time, less than three years ago, the raw materials was a topic exclusively tackled by ‘connaisseurs’. Today, it has become a strategic file, and the speed of its adoption shows need for action to secure a sustainable supply of critical raw materials (CRMs).

Standing at the core of the Green Deal Industrial Plan, together with the Net Zero Industry Act and the Reform of the electricity market design, the CRMA is a flagship initiative with a threefold objective: to increase and diversify the EU’s CRMs supply, to strengthen circularity, including recycling, and to support research and innovation (R&I) on resource efficiency and the development of substitutes. The bloc further consolidated this timely adoption with a set of complementary regulations and diplomatic initiatives, outlining a clear position ready to reduce reliance on third countries through export restrictions and screening for foreign direct investment across various sectors [e.g. forging strategic agreements with Chile, Greenland, Ukraine, Canada, Rwanda, and more recently Norway].

Read the official press release

Echoing the official communication, Commission Vice-President Valdis Dombrovskis declared for Euractiv: “Trade flows of critical raw materials are highly concentrated,” adding, “While we will continue to rely on imports, we need to massively diversify.”

The official document sets a threshold of 65% of the EU’s annual consumption of any CRM deriving from any single country. The CRMA establishes also a list of 34 critical and no less than 17 strategic raw materials considered crucial for the twin green and digital transition, as well as for defence and space industries.

In addition to the updated list of CRMs, the act introduces three targets for annual consumption of raw materials:

  • 10% for local extraction
  • 40% EU domestic processing threshold
  • 25% of supply emanating from recycled material

These changes modifying the recycling target reflect the increasing importance of paving a circular economy model that ensures a sustainable supply of raw materials.

Benefits of “offline programming”

Simulation environments have been widely used in robotics for demonstration and planning purposes. This typically takes place within a simulation software or any other platform that can replicate the robot’s dynamics, workspace and surrounding environment, and enable robotic programming. This replication system has proved to be cost- and time-efficient due to a series of advantages: no risk of disrupting the production by removing the robot from the production line, high flexibility allowing infinite number of configurations on a virtual model of the robot, reduced risk of equipment damage due to high predictability of malfunctions. For instance, operational industrial robots can be tested in a simulation environment before deployment. This process is often referred to as “offline programming”.

Researchers at Department of Engineering Sciences, University of Agder have been designing a simulator within a virtual environment to visualise and test various demanufacturing approaches for battery packs, allowing them to collect necessary data such as process duration, disassembly tools – all without the need of physical experiments. This innovative exploration not only streamlines data gathering but can also help identify and remove unforeseen bottlenecks in the disassembly process.

Environment configuration and use case application for battery pack demanufacturing

Using a simulation environment, known for its high-fidelity graphical capabilities, researchers at UiA were able to create a controlled virtual space ideal for visualising complex robotic processes and interactions related to demanufacturing electric vehicle (EV) batteries. The robotic cell design is decomposed across all the subtasks/segments of the disassembly process, with specific consideration to safety aspects and optimised efficiency and accessibility of robotic manipulators.

In order to study in depth and to demonstrate the efficacy of a proposed fully automated demanufacturing line, researchers at UiA meticulously recreated a virtual environment where they simulated the disassembly of a an EV battery pack. This simulation encompasses the entire process from automated discharging to the disassembly of packs into modules, subsequent characterisation, sorting, and finally, the disassembly of modules into individual cells. All elements of the simulation are animated using the simulation platform and a robotic operating system code, providing a holistic view of the potential automation within the demanufacturing process.

For this particular use case, researchers at UiA have calculated the time individually for each disassembly operation, reaching roughly between 12 and 14 minutes for the entire process.

The findings of this research that replicated the complete demanufacturing of EV LiB pack in a virtual, yet realistic industrial setting, illustrate the leverage of automated processes over conventional approaches conventionally relying on manual techniques. The simulation provides estimates for operation time for a given disassembly procedure (disassembly sequence and disassembly process). Upcoming steps will involve AI to generate and optimise the procedures. Additionally, the simulation can identify solutions to minimise human exposure to potential hazards associated with battery disassembly processes. Future in depth and multidisciplinary research is required to optimise the disassembly sequences and process in the simulated environment by training reinforcement learning agents and including a collision avoidance system, to name a few.

Ultimately, the aim of this research is to anticipate the increasing number of EV batteries that will be decommissioned soon, and to ensure a proper management of waste, while recovering all the resources available in clean mobility technologies.

An important component of a Li-ion battery (LiB), the electrolyte has a crucial role in the cell performance. The nonaqueous electrolyte is a multicomponent system consisting of a conductive salt, mainly LiPF6 (Lithium hexafluorophosphate – inorganic component), organic carbonate solvents and additives.

Numerous research initiatives are dedicated to the design of the electrolyte composition, aiming to optimized performance, increased safety, lifetime and streamlined costs. However, once a LiB reaches its end-of-life (EoL) stages, the electrolyte receives less attention in the favour of the valuable metals that can be recycled from the cathode: Li, Co, Mn, Ni, Al, Cu. Moreover, due to its volatility, toxicity and high flammability, the electrolyte recycling is less studied. When ignored, the spent electrolyte reacts with water to form fluoride, leading to its uncontrolled decomposition and/or evaporation, and thus generating an imminent environmental risk. Due to its composition that includes organic solvents, the presence of residual electrolyte in the black mass is considered hazardous, and it is often a reason hampering the recycling process.

Researchers at Chalmers University (CHA) ) developed a sub- and supercritical carbon dioxide (sc-CO2) extraction process to selectively recover the electrolyte from spent LiBs. Sc-CO2 extraction technologies are already widely employed in the food, beverage, pharmaceutical, and cosmetic industry. In a nutshell, sc-CO2 forms when CO2 surpasses its critical point at 31°C and 73.8 bar pressure. In this so-called supercritical state, CO2 demonstrates optimal mass-transfer characteristics and can be fine-tuned to alter its physicochemical characteristics by adjusting pressure and/or temperature. However, CO2 proves ineffective as a solvent for high molecular weight polymers and highly polar ionic compounds. However, the addition of a co-solvent or a modifier can significantly improve the solubility properties of sc-CO2, making this alternative a suitable process to selectively extract LiPF6 after solvent removal.

Researchers at CHA investigated different process parameters (pressure, temperature, extraction times) to understand their impact on the extraction behavior of different electrolyte solvents such as ethylene carbonate. Their analysis included both qualitative and quantitative results indicating the composition and the purity. Simultaneously, the research also monitored the process exhaust stream for potential formation of LiPF6 decomposition products. The findings showed that that the non-polar electrolyte solvents like dimethyl carbonate, diethyl carbonate, and ethyl methyl carbonate were successfully extracted using low-density CO2. The more polar electrolyte components such as ethylene carbonate and propylene carbonate were stepwise extracted by gradually increasing the system’s pressure. The developed technology is a game changer not only for electrolyte recycling but also for increased workplace and transportation safety due to removal of the flammable and hazardous substances from battery black mass. The simplicity of the processing design is an additional advantage of the technology.

During the past years, the increase in the use of lithium-ion batteries (LIBs) has become more prominent. An unsurprising trend, whatsoever, due to the widespread and rapid adoption of clean mobility applications, electronic devices, and energy storage systems. Despite their undeniable environmental and social benefits, several challenges lie ahead. In 2022, global lithium demand exceeded the supply despite an 180% increase, IEA reports. Recent communications already forecast the demand of lithium (Li) is expected to soar over the next decade, with mobility accounting for the main consuming market.

The current supply of primary resources is deemed insufficient for the growing demand. Approximately 60% of today’s lithium is mined for battery-related applications, a figure that could reach 95 percent by 2030, McKinsey reports estimate. But this rapid increase in the use of LIBs in EVs will introduce a large quantity of spent batteries in the near future. The alternatives to manage spent batteries include remanufacturing, repurposing and recycling, with the latter one playing a significant role from both ecologic and economic points of view.

Current recycling processes lack selectivity in recovery control and require significant consumption of reagents and energy. The research conducted by the RHINOCEROS partners at Sapienza University of Rome (UoS), Department of Chemistry, aims to develop an electrochemical process for selective extraction of Li from electrodic powder of end-of-life (EoL) LIBs. This concept simulates the charging process of a LIB with an aqueous electrolyte and a cathode material (counter electrode) that facilitates water reduction. The hydroxyls freed by water reduction and the Li + cations deintercalated by the anode will form a LiOH solution.

Using two samples – a commercial powder, respectively one coming from EoL LIBs, and testing the delithiation process using various parametres, UoS researchers obtained:

  • Li extraction of 99% from commercial powder
  • Li extraction of 82% from waste powder

The lower Li extraction on EoL electrode powders compared to commercial ones is due to the presence of SuperP [a high purity and structured carbon black powder with a moderate surface area for the lithium-ion industry], which oxidises under delithiation conditions.

Europe stands at a turning point in its journey towards establishing a competitive European value chain for batteries. Important steps have been taken in encouraging battery manufacturing plants, only to mention here the inauguration of the first gigafactory by Northvolt in Sweden. Yet, the market demand for batteries continues to surge, fueled not only by the electric vehicle sector but also by other mobility applications and stationary storage needs. The recently launched  Quarterly EU Electricity Market Report Q3 ’23 indicates over 600,000 new battery electric vehicles (BEVs) were registered in Q3 ’23, 36% higher than the corresponding quarter in 2022 and counting for 24% market share.

In response to these record demands, the European batteries research and innovation (R&I) community has been dedicated to supporting the establishment of this industrial value chain in Europe, aided by public funding, including by the European Union. Various R&I projects under the umbrella of the BATT4EU Partnership (established under Horizon Europe Programme in 2021), RHINOCEROS included, are sharing forces within the Cluster Hub “Production of materials for batteries from European resources” to address common challenges.

Motivated by the global geopolitical developments, the strategic role batteries play in achieving Green Deal objectives and the ever-evolving nature of battery technologies, Europe recognises the critical need for strategic alignment among stakeholders. Replacing the BATT4EU SRIA of 2021 and the Batteries Europe SRA of 2020, the 2024 SRIA outlines key strategic actions that the European Batteries R&I Community will undertake to advance collaborative research projects facilitated by the BATT4EU Partnership. Different from the previous strategic agendas, the 2024 roadmap goes beyond specific chemistries, leveraging also the power of disruptive (digital) technologies to advance research across all battery types, including material science, manufacturing and recycling processes.
The new agenda draws on the roadmaps published by Batteries Europe and Battery 2030+, compiling inputs from numerous European battery experts, offering recommendations on short, medium, and long-term objectives. It emphasises the need for coordinated action not only at the European level but also within national and regional programmes.

The 2024 SRIA points to the following six imperatives which are necessary to set the foundations and support a competitive battery value chain in Europe:

• Ensure that (BATT4EU) research results reach gigafactories and the markets, through pilots, demonstrators and improved decision making aided by digital tools.
• Increase the strategic autonomy of Europe by reducing the reliance on foreign critical raw materials by supporting local and circular supply chains and support research into different battery chemistries, including sodium-ion technologies.
• Improve battery affordability to accelerate the green transition and keep the European industry competitive by improving batteries based on materials that are more abundant and pushing for better integration into end-use applications.
• Improve the flexibility of battery manufacturing and recycling systems to reduce lock-in effects and respond quickly to changes in a rapidly developing industry.
• Implement a safe and sustainable by design framework for batteries, which plays to European strengths, and which will help reduce emissions and use of substances of concern, improve safety and allow for the integration of smart functionalities.
• Support the continuity of excellent European battery research and academic-industrial cooperation by improving access to research facilities and pilot lines, use research projects to build up a skilled workface, and by avoiding gaps in research through continued funding, which will bind talented researchers to Europe.

RHINOCEROS attending Shifting Economy Week

From 21 to 25 November 2023, the city of Brussels hosted the Shifting Economy Week, an annual event dedicated to showcasing transformative projects that aim to pave the way to an economy that is low-carbon, regenerative, and equally circular. The 2023 exhibitors’ line-up included, among other regional stakeholders, our partner Watt4Ever (W4E), industrial partner specialised in the development of innovative solutions for energy storage and management. W4E leveraged its presence at Shifting Economy Week to to raise awareness about the importance of circular economy principles in the context of the battery industry.

During the same event, W4E’s CEO, Aimilios Orfanos, was invited to speak at the BeCircular conference, an event dedicated to presenting concrete examples of circular economy approaches put in place by Brussels-based companies. He shared insights from W4E’s experience in developing second-life battery systems for electric vehicles, emphasising their potential benefits in terms of environmental impact and cost savings. Simultaneously, the CEO also highlighted the challenges faced by the industry in implementing circular business models, including regulatory barriers and market incentives.

RHINOCEROS at its second participation at Circular Wallonia Days

A few days after attending Shifting Economy Week, W4E represented the RHINOCEROS project at the Circular Wallonia Days, held on 13 and 14 December 2023. Centred around advancing the circularity of the batteries value chain, the event brought together stakeholders from academia, industry, and government to discuss strategies for improving the sustainability of battery production, use, and disposal. The focus topics covered recycling technologies, supply chain transparency, and policy measures to support the transition to a circular battery economy.

Despite a different objective, the RHINOCEROS project partners have shown growing interest in the Digital Battery Passport, an initiative of FREE4LIB, a sister project from the Cluster Hub “Production of raw materials for batteries from European resources”. This collaboration shows our commitment to contributing to the European battery community through the exchange of knowledge and experience.

The FREE4LIB workshop had a three-fold objective, including a brief presentation of the preliminary results of the battery passport concept development, the outline of the implementation challenges and potential follow-ups of industrial scale-up, and the clear differentiation between battery second use (B2U) versus recycling. The event drew approximately 50 participants from various segments of the battery value chain, which ensured a comprehensive and multifaceted perspective of the subject matter.

The introductive session presented the FREE4LIB project, briefly highlighting past achievements and focusing mainly on the remaining activities outlined in the workplan. The following session was led by Julius Ott (industrial engineer with expertise in circular economy at Karl-Franzens-Universität Graz). During the past year, researchers at Univ. of Graz worked on finalising data collection and processing related to the development of a data model of the digital passport platform which aims to close the information gap between beginning-of-life (BoL) and end-of-life (EoL) battery lifetime. This interactive session turned out to be an appropriate opportunity for researchers at Univ. of Graz to present the outcomes of their data collection and handling, and to evaluate their relevance within the reality portrayed by the workshop attendees.

Participants, predominantly familiarised with the EU-funded battery projects, confirmed the findings reported by Univ. of Graz. However, they also raised concerns about data sharing. The outcomes of the interactive session, complementing prior research, will serve as valuable guidance for the FREE4LIB project in implementing the battery passport within their project.

On Thursday, 16 November, during the 2023 edition of the Raw Materials Week, the twelve EU funded projects that constitute the Cluster Hub ‘Materials for batteries’ gathered for their annual event in Brussels.

The Cluster Hub has been initiated last year during the 7th edition of the Raw Materials Week. The main objective of the meeting was to meet and discuss the latest developments in the participating projects as well as the new challenges and opportunities discovered through the projects’ lifetime. Nader Akil, Operations Manager at PNO Innovation, inaugurated this second edition outlining the motivation behind the hub’s establishment. He underlined the positive reception and sustained interest from various stakeholders keen on joining this initiative.

Discover and/or rediscover the first edition of the Cluster Hub workshop

Co-organised by RELiEFEXCEEDENICON and RAWMINA, the event was also the opportunity to welcome the four new members of the Cluster (EXCEEDRAWMINAMETALLICO and CRM-geothermal). the workshop gathered nearly 100 organisations driving the production and the recycling of raw materials for battery applications from primary and secondary resources.

Building on the initial objective of creating an environment that could foster knowledge exchange on different approaches for the recycling and recovery for battery applications, the event focused on three major topics that depict the transversality characterising the projects: the raw materials through research and science, the roles and challenges of industry and market for raw materials, and the raw materials under the scope of sustainability, durability and social acceptance. During this annual meeting, an interactive session led by Anish Patil from TechConcepts and representing the RELiEF project had the objective of Mapping the European battery material recycling landscape – more details to be found below, in the section referring to the interactive session.

Research and science unlocking new opportunities in raw materials

The first session was moderated by Sonia Matencio from LEITAT, representing the RAWMINA project. This session had the objective of discussing the raw materials through research and science, under the scopes of mining, refining, processing as well as the battery data. Sonia introduced this topic under the scope of RAWMINA, explaining the integrated innovative pilot system for Critical Raw Materials recovery from mine waste in a circular economy context. To this end, Christophe Aucher, from LEITAT as well, highlighted the need on an open battery passport system to better reflect and account for any adaptations that might be required due to the changing regulatory landscape.

Sonia welcomed afterward Brecht Dewulf from KU LEUVEN and representing ENICON, who discussed the sustainable processing of Europe’s low grade sulphidic and lateritic Ni/Co ores and tailings into battery grade metals. The idea behind this was to show all the potential of Ni/Co resources for Europe.

Xochitl Dominguez from VITO concentrated her speech on gas-diffusion electrocrytallisation (GDEx), a crucial topic for the projects LiCORNE and RHINOCEROS she works with. GDEx is an electrochemical process of reactive precipitation of metals in solution with oxidising or reducing agents produced in-situ by the electrochemical reduction of a gas, in a gas-diffusion electrode. This was followed by Katrin Kieling from GFZ Potsdam, working there for the CRM-geothermal project and shortly explained the challenges of extracting critical raw materials from geothermal fluids. To conclude this first session, Sandra Pavón from Fraunhofer IKTS explained the demonstration of battery metals recovery from primary and secondary resources through a sustainable processing methodology in the METALLICO project.

Insights from stakeholder perspectives: Interactive session on key EU Policies and priorities

The annual meeting followed its course with an interactive session led by Anish Patil, which scrutinised stakeholders’ perspectives on the Green Deal Industrial Plan, Net Zero Industrial Act, Critical Raw Materials Act and the European Battery Regulation 2023. Mentimeter facilitated this interactive session, engaging the audience to explore how these policies intersect, complement each other, and identify critical measures and incentives for achieving their objectives.

Over 30 persons participated in the live-poll proposed, which results display the priority to be set on funding and state aid regarding ranking the four pillars of the Green Deal Industrial Plan in order of relevance (followed by skills development, conductive regulation, and open and fair trade). Another major topic regarding the stimulation of investment in net Zero technologies, the majority of answers placed the ‘enhanced skills’ as first priority, shortly followed by facilitating the access to the market.

Lastly, the participants were divided regarding the critical measures to implement in the EU to stimulate investment in building domestic capacities for extraction of critical raw materials (CRMs). Although the majority opted for ‘cutting red-tape and accelerated permitting’, approximately half of the answers evoked uncertainty, which emphasised one more time the need to engage with policy makers as external stakeholders in all projects.

Navigating the nexus: industry challenges, market dynamics, social acceptance and sustainability

This interactive workshop was followed by two sessions, which aimed at discussing the challenges and opportunities of raw materials within the frame of industry and market, as well as the social acceptance, sustainability, and durability.

Alan Gonzalez from PNO Innovation Begium, representing LiCORNE, moderated the industry part, whereas Sam Hoefman from RELiEF moderated the last session on social acceptance, sustainability, and durability. Distinguished panellists took the stage to engage in debates on various topics.

Edvarts Emerson, Production and Testing Engineer at Watt4Ever, presented his work on the benchmark depository of 2nd life use of lithium in batteries, acceptance criteria and guidelines, work developed within the RHINOCEROS project. Benjamin Wilson, representing the RESPECT Project, displayed Aalto University’s work advancing efficient, sustainable, innovative and safe battery recycling processes in the EU. Laura Kainiemi from LUT University, representing the RELiEF Project, Konstantinos Komnitsas from the Technical University of Crete (TUC), on behalf of EXCEED, and Vitor Correia from INTRAW for the CRM-geothermal project, collectively debated the role and impact of social acceptance among affected communities, the importance of triggering new dialogues on responsible mining activities, and the joint involvement of regional, national and European authorities, academia, industry partners, and citizens in shaping these initiatives.

A big thank you to all participants for this co-creative and very constructive and inspiring meeting.
