Sustainable routes for synthetic graphite production for high-performance Lithium-Ion battery anodes

Sustainable routes for synthetic graphite production for high-performance Lithium-Ion battery anodes

SOURCE will develop, improve and demonstrate in an industrially relevant environment economically and environmentally viable routes for producing battery-grade synthetic graphite for high-performance anodes. SOURCE will first enable the production of carbon precursors from heterogeneous raw material sources, including alternative sustainable petroleum feedstocks, bio-waste and black mass from recycled batteries, to reduce the current dependence of synthetic graphite from petroleum-based coke. Sustainable technologies to transform these materials into carbon feedstock will be demonstrated at TRL6/7. Additionally, low-temperature graphitization techniques (<1000°C vs. 3000°C) will be demonstrated, with >30% potential reduction of the energy consumption and production cost. Innovative high-performance Carbon@graphite, Si@graphite, and graphene@graphite coatings and anode (capacity > 350 mAh/g) will be formulated, fabricated, tested and validated in 1Ah prototype pouch cells at TRL7. Recycling processes to recover graphite at low cost with >90% purity from LiB EoL batteries and >98% purity from anode production scrap will be demonstrated at TRL7. LCA and LCC analysis will be delivered to accurately assess the sustainability of SOURCE synthetic graphite and value chain defining the best routes to ensure economic and environmental sustainability. SOURCE brings together key EU industries with main businesses in graphite precursors and synthetic graphite production, and advanced anode formulation, supported by EU leading RTOs forming the complete value chain to produce high quality synthetic graphite in a sustainable and economic way. SOURCE achievements will increase EU competitiveness and independence from foreign graphite suppliers and anode manufacturers. SOURCE technologies and materials will be directly exploited by its top-level industrial partners with a direct market presence and already established commercial channels, ensuring SOURCE value chain sustainability.
