Unravelling the effect of benzoquinone intercalators on the aqueous zinc-ion storage performance toward a vanadium pentoxide cathode

We demonstrate V 2 O 5 cathodes with benzoquinones intercalation. The intercalated BQ4Br expands V 2 O 5 lattices and improves reaction kinetics, endowing V 2 O 5 -BQ4Br with higher capacity and cycle stability.
