In situ grown 2D hydrated ammonium vanadate nanosheets on carbon cloth as a free-standing cathode for high-performance rechargeable Zn-ion batteries

Ultrathin 2D ammonium vanadate nanosheets were grown on alkali-treated carbon cloth via a facile hydrothermal method. This free-standing cathode enables fast ion/electronic transport and reduces the aggregation of ultrathin ammonium vanadate nanosheets.
