A European battery research initiative has taken a significant step towards commercialising recycled graphite, demonstrating that recovered battery materials can be used in industrial cell production rather than remaining limited to laboratory testing.
The EU-funded SAFELOOP programme has incorporated approximately 500 kg of battery-grade recycled graphite into a manufacturing campaign conducted with Turkish battery producer Aspilsan Enerji. The initiative aims to establish whether recycled materials can meet the technical requirements of large-scale battery manufacturing and support the development of more resilient European supply chains.
Recycled Graphite Enters Battery Cell Production
As part of the manufacturing campaign, Aspilsan Enerji produced 18650-format lithium-ion cells incorporating recycled graphite alongside high-purity alumina supplied by Cadoux.
The cells progressed through several key manufacturing stages, including electrode preparation, coating, assembly and formation. Completing these processes represents an important step beyond laboratory-scale material testing, where promising results do not necessarily translate into reliable industrial performance. The battery cells are intended for integration into modules for an electric bus manufactured by Bozankaya. Their eventual application will depend on further assessments of performance, safety and manufacturing consistency.
The milestone demonstrates that recovered graphite can be introduced into an established battery-production process. It does not yet confirm commercial deployment or establish that the materials are ready for widespread use.
Industrial Qualification Remains the Critical Challenge
For battery recyclers, recovering valuable materials from end-of-life batteries is only part of the commercial challenge. Recovered graphite must also meet demanding specifications and perform consistently throughout the manufacturing process. Materials that deliver satisfactory results in laboratory tests can encounter difficulties during electrode coating, cell formation or extended cycling. Variations in material quality can affect manufacturing efficiency, battery durability and safety, making industrial qualification essential before commercial adoption.
SAFELOOP is moving recycled graphite into this more demanding phase of evaluation. The results will help establish whether the recovered material can be used reliably in battery cells and potentially progress towards broader commercial qualification. The programme is also assessing Cadoux’s high-purity alumina for functional battery applications, including ceramic coatings. This creates an additional opportunity to evaluate materials intended for use in advanced battery manufacturing.
Despite the progress, the manufacturing campaign should not be interpreted as evidence of a secured commercial offtake agreement or confirmed recurring revenue. Further testing is required to establish whether the materials can satisfy the performance and consistency requirements of industrial customers.
European Battery Supply Chains Seek Greater Material Security
The development addresses a structural challenge facing Europe’s battery industry: reducing dependence on imported battery materials and processing capacity. Graphite is a major component of lithium-ion battery anodes, making a reliable supply of battery-grade material essential to cell manufacturing. Although recycling can recover graphite from used batteries, its commercial value depends on whether the recovered material can be processed and reused to the required specifications.
Successful recycling could help diversify supply sources and reduce reliance on virgin material. Achieving this outcome requires more than demonstrating high purity. Recovered graphite must deliver consistent results under real manufacturing conditions and throughout a battery’s operating life. The ability to incorporate recycled feedstock into finished cells is therefore an important indicator of progress towards a more circular battery supply chain.
Performance and Cost Will Determine Commercial Potential
The next stage for SAFELOOP is to demonstrate that cells containing recycled graphite can achieve competitive cycle life, charging performance and safety. Repeatability will also be crucial, as manufacturers need confidence that material quality and cell performance can be maintained across successive production batches. If the results meet the required standards, the programme could strengthen the case for investment in European graphite-recovery facilities and battery-material recycling infrastructure.
Nevertheless, the transition from factory trials to commercial production will depend on whether recycled materials can be supplied consistently and at costs competitive with virgin graphite. Manufacturing reliability, qualification requirements and the ability to scale recovery processes will all influence the economics. SAFELOOP’s latest achievement marks progress in moving battery-grade recycled graphite from laboratory development into factory-scale manufacturing. The decisive test will be whether that progress can translate into repeatable cell performance, commercially viable production and wider adoption by battery manufacturers.
