Abstract : The Cover Feature shows the unique fullerene‐like hollow polyhedrons of a P2‐type Na0.67 Ni0.15 Mn0.85 O2 cathode. The sodium‐ion full battery based on this material without pre‐sodiation treatment could deliver a high energy density, demonstrating its great potential for grid‐level applications.More information can be found in the Communication by B.
