Abstract Sodium super‐ionic conductor (NASICON)‐structured phosphates are emerging as rising stars cathodes for sodium‐ion batteries. However, they usually suffer from a relatively low capacity due to the limited activated redox couples and intrinsic electronic conductivity. Herein, reduced graphene oxide supported NASICON Na 3 Cr 0.5 V 1.5 (PO 4 ) cathode (VC/C‐G) is designed, which displays ultrafast (up 50 C) ultrastable (1 000 cycles at 20 + storage properties.
