Anthraquinone-intercalated V2O5 with Al3+ for superior zinc-ion batteries: reversible transformation between disorder and order

Oxygen-deficient anthraquinone (AQ)-intercalated vanadium oxide displays an ultralong lifespan in the electrolyte with Al 3+ due to the dual-pillar of AQ/Al 3+ and reversible disorder–order conversion on the (00 l ) facets.
