Rubber, an organic polymer, is notoriously difficult to degrade. The large quantities of waste rubber decommissioned annually pose significant ecological and environmental challenges. This study proposes a novel strategy to transform waste rubber into high-performance carbon anode materials for sodium-ion batteries (SIBs) through gas-solid intersection modification with ethanol-assisted heat treatment. This innovative approach optimizes the microstructure of rubber-derived carbon, effectively reducing the surface sulfur content and forming more pseudographite microcrystalline structures. As a ...
