An aqueous zinc-ion battery (ZIB) shows superiority due to intrinsic safety, cost-effectiveness, and environmental friendliness, but the cathode materials commonly cannot simultaneously satisfy the requirement of quick and reversible zinc ion intercalation/deintercalation, leading to poor cycling durability and unsatisfactory capacitance. In this work, we regulate vanadium oxide by ion doping and surface defect modulation through a simple hydrothermal method and postprocessing by low-temperature annealing in a Natmosphere. The prepared materials present a high specific capacity of 398 mA h gat 0.5 A gcurrent density and considerable cyclic stability (capacity maintains 161 mA h gat 5 A gafter 10,000 discharge/charge cycles). This study lays a foundation for cathode material preparation and improvement for aqueous ZIBs.
