Overview

This review highlights advances in interlayer engineering and ion kinetics for improved zinc-ion batteries, indicating a framework for future research.

Key Points

  • The study correlates the crystallographic evolution of v2o5 with voltage plateaus and capacity decay, enhancing understanding of Zn2+/H2O co-intercalation.
  • Emerging synthesis routes are compared, revealing their impact on conductivity and rate capability, with specific surface area directly linked to battery performance.
  • Interlayer-expansion strategies show how modifications can improve Zn2+ diffusivity, lattice strain, and dissolution resistance, crucial for battery longevity.
  • Integrating experimental findings with theoretical models distills actionable design principles for achieving high capacities and excellent retention in batteries.
