abstract = {Aqueous Zn-ion batteries (AZBs) have been considered as one
of the most promising large-scale energy storage systems,
owing to the advantages of raw material abundance, low cost,
and eco-friendliness. However, the severe growth of Zn
dendrites leads to poor stability and low Coulombic
efficiency of AZBs. Herein, to effectively inhibit the
growth of Zn dendrites, a new strategy has been proposed,
i.e., tuning the surface energy of the Zn anode. This
strategy can be achieved by in situ doping of Sn heteroatoms
in the lattice of metallic Zn via codeposition of Sn and Zn
with a small amount of the SnCl2 electrolyte additive.
Density functional theory calculations have suggested that
Sn heteroatom doping can sharply decrease the surface free
energy of the Zn anode. As a consequence, driven by the
locally strong electric field, metallic Sn tends to deposit
at the tips of the Zn anode, thus decreases the surface
energy and growth of Zn at the tips, resulting in a
dendrite-free Zn anode. The positive effect of the SnCl2
additive has been demonstrated in both the Zn∥Zn symmetric
battery and the Zn/LFP and Zn/HATN full cell. This novel
strategy can light a new way to suppress Zn dendrites for
long life span Zn-ion batteries.},
