Implication

Materials experiment demonstrates in situ transformation of vanadium oxide into zinc vanadate nanoflakes for aqueous zinc-ion batteries, highlighting a pathway to stable, high-capacity cathodes.

Key Points

  • To develop a high-capacity, cycle-stable cathode for aqueous zinc-ion batteries by overcoming the severe capacity degradation typical of layered vanadium pentoxide.
  • Synthesized ultrathin, binder-free vanadium pentoxide (V2O5) atomic layers on a conductive substrate using atomic layer deposition.
  • Investigated the in situ structural transformation of the V2O5 cathode and evaluated dissolution mechanisms across different aqueous zinc-salt electrolytes.
  • Observed the rapid in situ transformation of V2O5 atomic layers into Zn3V2O7(OH)2·2H2O nanoflake clusters capable of both zinc-ion and proton co-intercalation.
  • Achieved high capacity alongside exceptional cycling stability, enabled by nanosized thickness, abundant active sites, strong substrate bonding, and suppressed vanadium dissolution.
