The Cover Feature shows a new nanocomposite with a stable sandwich framework structure for sodium‐ion battery cathodes. The nanocomposites are prepared by using multifunction sodium lignosulfonate as the organic ligand of a vanadium metal‐organic framework precursor and a carbon source. The unique sandwich framework structure is composed of Na 3 V 2 (PO 4 ) 3 ultrathin sheets and N‐doped hard carbon ultrathin sheets, ensuring fast electron transmission and Na+ migration for ultrahigh rate performance and excellent long cycling life.
