A self-supporting VO2@MXene electrode with boosted Zn2+ (de)intercalation kinetics and cycling stability for aqueous zinc-ion batteries.
Vanadium dioxide (VO2) with its high theoretical capacity is one of the promising cathodes for aqueous zinc-ion batteries (AZIBs) for safe and sustainable energy storage. However, its poor electrical conductivity and structural degradation have limited its rate performance and long-term stability. Herein, we present a...
