摘要

生物相容性器件以可穿戴和植入式器件的形式广泛应用于现代生活和医疗领域，对电池的生物相容性、高安全性、低成本和优异的电化学性能提出了更高的要求，成为开发可行的生物相容电池的评价标准。本文通过在新西兰兔身上进行电池植入试验和泄漏场景模拟，证明硫酸锌电解质具有较高的生物安全性，是生物相容性锌离子电池（ZIBs）的理想锌盐之一。此外，为了缓解弱酸性电解质中臭名昭著的枝晶生长和析氢现象，并提高其操作稳定性，引入Sn杂核来稳定锌阳极，这不仅有利于平面锌沉积，而且有助于提高析氢过电位。最后，对称电池的长寿命为1500小时，Zn-MnO2电池在0.5A g-1下的比容量为150mAh g-1，Zn-NH4V4O10电池在5A g-1下获得212mAh g-1。这项工作可能为生物相容性ZIB的细胞成分的生物安全性提供独特的视角。

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

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.

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary and open-access journal that focus on science, experiments, engineering, technologies and applications of nano- or microscale structure and system in physics, chemistry, biology, material science, pharmacy and their expanding interfaces with at least one dimension ranging from a few sub-nanometers to a few hundreds of micrometers. Especially, emphasize the bottom-up approach in the length scale from nano to micro since the key for nanotechnology to reach industrial applications is to assemble, to modify, and to control nanostructure in micro scale. The aim is to provide a publishing platform crossing the boundaries, from nano to micro, and from science to technologies.
