Hetero Nucleus Growth Stabilizing Zinc Anode for High-Biosecurity Zinc-Ion Batteries

Abstract

Highlights Animal models are applied to evaluate the biosecurity and biocompatibility of the zinc-ion batteries with the electrolytes of different zinc salts. Leakage scene simulations and histological analysis are employed in investigating the tissue response after battery implantations, in which ZnSO4 exhibits higher biosecurity. Sn hetero nucleus is introduced to stabilize the zinc anode, which not only facilitates the planar zinc deposition, but also contributes to higher hydrogen evolution overpotential.
