3D Bio-Graphene from Biochar via Catalytic Graphitization for Li–S Batteries
This four-year project will develop and validate a scalable process to convert the biochar into high-performance 3D bio-graphene for lithium–sulfur (Li–S) batteries. Using Fe-catalytic graphitization, molten-salt templating, and controlled Fe-residue tuning, the material will combine high conductivity, hierarchical porosity, and polar active sites for superior sulfur utilization, lean electrolyte operation, and long cycle life. Biochar will be chosen from Swedish forest waste, synthesis and scale-up performed at KTH, and electrochemical validation conducted at Uppsala University’s Ångström Advanced Battery Center. The outcome will strengthen Sweden’s battery value chain by enabling domestic, resource-efficient production of a critical Li–S component, supporting the integration of this emerging chemistry into Swedish industry.
