22 December 2025 — Presented at BID in the session “End of life, start of supply: Advancing battery recycling in Europe”, GR4FITE3 showed how recycled and regenerated graphite can underpin a resilient, low-impact European battery value chain.
During Battery Innovation Days (BID), GR4FITE3 highlighted its advanced approach to graphite recycling as a critical enabler for Europe’s sustainable battery ecosystem. The project focuses on Graphite Resilience For lithium-Ion baTtery anodes by building a fully integrated, European, end-to-end supply chain for anode active materials.
GR4FITE3 brings together environmentally responsible mining of natural crystalline flake graphite from Europe’s largest known graphite resource with highly innovative, continuous, and low-energy upgrading processes. A distinctive feature of the project is the integration of recycled and fully regenerated synthetic graphite, combined with silicon nanoparticles, to create a unique anode particle architecture. These materials are then used to manufacture high-density anodes, assemble lithium-ion cells, develop battery modules, and certify them for safety and performance before deployment by European OEMs, including an electric bus manufacturer and a utility grid developer.
A key challenge highlighted by project coordinator Eleonora Calì (RINA) during the BID session is the systematic loss of graphite in conventional battery recycling. In both hydrometallurgical and pyrometallurgical routes, recycling efforts traditionally focus on recovering valuable metals such as lithium, cobalt, nickel, and manganese. As a result, graphite is often burned, discarded, or left mixed in black mass. GR4FITE3 responds to this gap with an environmentally sustainable, direct-recycling-based methodology specifically designed to recover and regenerate graphite.
Within the project, a multistep regeneration route has been developed to recover anode graphite from different battery types, including a Toshiba laptop cell and a large-format LFP battery (HWE200A). The process begins with complete mechanical dismantling of the cells, followed by separation of individual components and removal of the anode coating from the copper foil. The recovered active material is then purified using diluted nitric acid to eliminate residues and cross-contamination.
After chemical treatment, the graphite undergoes controlled thermal annealing in different atmospheres. The final steps include crushing and sieving to obtain a homogenized, regenerated graphite fraction suitable for reuse in new anode formulations.
By presenting these results at BID, GR4FITE3 reinforced the message that graphite recycling is a strategic necessity for Europe; the project demonstrates that regenerated graphite can meet battery-grade requirements, reduce environmental impact, and strengthen Europe’s independence in critical raw materials for electric mobility and energy storage.
