This work demonstrates improved performance in zinc metal anodes, suggesting a new strategy for aqueous zinc-ion batteries.
Key Points
The aim is to enhance the performance and stability of zinc metal anodes used in aqueous zinc-ion batteries by developing an effective solid electrolyte interphase.
Developed an in situ self-construction strategy for ZnCr2O4-based SEI layer on zinc anodes.
Characterized the ZCO@Zn electrode's properties and electrochemical performance.
Evaluated hydrophilicity and corrosion resistance of the modified anode during cycling.
ZCO@Zn electrodes show enhanced cycling stability, operating over 2800 hours at 1 mA cm−2.
Demonstrated a 94.03% retention of initial capacity after 2000 cycles when paired with NH4V4O10 cathode.
Reduced HER overpotential and improved corrosion potential were observed.
