Na 7 V 3 (P 2 O 7 ) 4 is capable of exhibiting 4.13 V of the redox potential as a cathode material for Na ion batteires, as revealed by the structural and electrochemical characterizations from first‐principles calculations and experiments. The cyclability of Na 7 V 3 (P 2 O 7 ) 4 is respectably stable (75% retention after 600 cycles), which is attributed to the low volume change (1%) during cycling.
