摘要

由钛酸锌（ZTO）组成的高Zn2+导电性的富锌人工固电解质界面层（SEI）作为智能离子过筛桥，有利于Zn2+而非阴离子快速迁移到Zn表面，实现均匀的Zn沉积和抑制副反应。因此，ZTO@Zn阳极具有长时间可逆镀锌/剥离（4500 h）和高库仑效率（99.9%）。

Intelligent ion-sieving bridge enabled by zinc-rich artificial SEI Layer with high Zn2+-conductivity for reversible zinc metal anode

A zinc-rich artificial solid-electrolyte interphase (SEI) layer with high Zn2+-conductivity composed of zinc titanate (ZTO), serving as an intelligent ion-sieving bridge, facilitates rapid migration of Zn2+ rather than anions to the Zn surface, realizing uniform Zn deposition and inhibition of side reactions. Consequently, the ZTO@Zn anodes exhibit long-time reversible Zn plating/stripping (4500 h) and high Coulombic efficiency (99.9%).
