abstract = {Recently, aqueous zinc-ion batteries (ZIBs) have become
increasingly attractive as grid-scale energy storage
solutions due to their safety, low cost, and environmental
friendliness. However, severe dendrite growth,
self-corrosion, hydrogen evolution, and irreversible side
reactions occurring at Zn anodes often cause poor
cyclability of ZIBs. This work develops a synergistic
strategy to stabilize the Zn anode by introducing a
molybdenum dioxide coating layer on Zn (MoO$_2$@Zn) and
Tween 80 as an electrolyte additive. Due to the redox
capability and high electrical conductivity of MoO$_2$, the
coating layer can not only homogenize the surface electric
field but also accommodate the Zn$^{2+}$ concentration field
in the vicinity of the Zn anode, thereby regulating
Zn$^{2+}$ ion distribution and inhibiting side reactions.
MoO$_2$ coating can also significantly enhance surface
hydrophilicity to improve the wetting of electrolyte on the
Zn electrode. Meanwhile, Tween 80, a surfactant additive,
acts as a corrosion inhibitor, preventing Zn corrosion and
regulating Zn$^{2+}$ ion migration. Their combination can
synergistically work to reduce the desolvation energy of
hydrated Zn ions and stabilize the Zn anodes. Therefore, the
symmetric cells of MoO$_2$@Zn∥MoO2@Zn with optimal 1 mM
Tween 80 additive in 1 M ZnSO$_4$ achieve exceptional
cyclability over 6000 h at 1 mA cm$^{-2}$ and stability
(>700 h) even at a high current density (5 mA cm$^{-2}$).
When coupling with the VO$_2$ cathode, the full cell of
MoO$_2$@Zn∥VO$_2$ shows a higher capacity retention
(82.4\%) compared to Zn∥VO$_2$ (57.3\%) after 1000 cycles
at 5 A g$^{–1}$. This study suggests a synergistic
strategy of combining surface modification and electrolyte
engineering to design high-performance ZIBs.},
