چکیده انگلیسی
Rechargeable aqueous zinc-ion batteries (ZIBs) are very promising energy storage systems owing to their low cost, high reliability, and high volumetric energy density; however, the stiff challenge for the progress of ZIBs is the lack of suitable materials that permit divalent ion-intercalation/deintercalation with fast kinetics, long cycling durations, and high rate capabilities. Herein, we demonstrate V10O24·12H2O dendrites with a large interlayer spacing of 1.4â¯nm, fabricated through a simple hydrothermal method. The unique, open, and stable structure complemented by a mixed valence enables a satisfactory battery performance: a specific capacity of 164.5â¯mAh gâ1, long-term cycling stability of 80.1% capacity retention after 3000 cycles, and high power density of 12247.8â¯Wâ¯kgâ1 at a high energy density of 88.5â¯Wh kgâ1. This study provides a viable and attractive cathode material for practical ZIBs.
