Capacity-enhanced and kinetic-expedited zinc-ion storage ability in a Zn₃V₃O₈/VO₂cathode enabled by heterostructural design

Abstract

Heterostructured double-phase composites are a promising electrode candidate for high-performance secondary metal batteries due to their superior capacity and ions transfer kinetics compared with the pristine phase. Herein, a Zn3V3O8/VO2...

Mg2VO4/VO2 Nanocomposites as Aqueous Zinc Ion Battery Cathodes with High Capacity and High Ion Diffusion Rate

“…39 The introduction of vanadium-based heterostructure composites is a reasonable strategy for improving the conductivity and rate performance. 40 Yang et al have developed a Zn 3 V 3 O 8 /VO 2 (ZVO/VO) heterostructure with abundant phase boundaries, which was designed as the cathode for AZIBs. ZVO/VO showed superior capacity and cycling stability compared to pristine ZVO and VO.…”

“…ZVO/VO showed superior capacity and cycling stability compared to pristine ZVO and VO. 40 42 Liu et al designed the V 6 O 13 /VO 2 electrode materials with abundant phase boundaries and oxygen defects. The boundaries between the two phases provide sufficient diffusion channels for Zn 2 + transfer.…”
