Abstract
Na7V3(P2O7)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 Na7V3(P2O7)4 is respectably stable (75% retention after 600 cycles), which is attributed to the low volume change (1%) during cycling. © 2016 WILEY-VCH Verlag GmbH & Co.
