Lignin-derived carbon framework is developed for reversible sodium deposition. This framework boosts an expansive specific surface area and a wealth of oxygen-rich functional groups, which serve to cushion the volume fluctuations of sodium metal throughout the electrochemical cycle, directing the even deposition of sodium ions.
