High-performance Zn-ion batteries constructed by conversion of surface-oxidized vanadium nitride into Zn(OH)VO·2HO with oxygen defects

Herein, surface-oxidized vanadium nitride (O-VN) is synthesized by a one-step hydrothermal method without multi-step reactions, and is applied as a cathode material for aqueous zinc ion batteries. After in situ electrochemical activation, it turns into Zn 3 (OH) 2 V 2 O 7 ·2H 2 O with copious oxygen...
