On page 6555, Q. Y. An, L. Q.Mai, and co‐workers demonstrate the existence of ionized oxygen in sodium vanadium oxide nanorods by using high time resolution in situ X‐ray diffraction and a series of ex situ measurements. The formation of ionized oxygen is suppressed by controlling the voltage window, which results in a great increase of capacity retention from 26% to 80%.
