摘要
在锌(Zn)电极上构建固体电解质相(SEI)是稳定锌电极/电解质界面的有效策略。然而,锌电极的单层 SEI 在反复镀锌/剥锌过程中会发生破裂,从而导致失效。在此,我们提出通过添加 1,3-二甲基-2-咪唑烷酮作为代表性电解质添加剂,构建一种坚固的双层 SEI,它能同时实现均匀的 Zn2+ 传输和持久的机械稳定性,从而提高锌电极的锌利用率(ZUR)和库仑效率(CE)。Zn 表面的这种双层 SEI 由富含结晶 ZnCO3 的外层和富含无定形 ZnS 的内层组成。有序的外层提高了循环过程中的机械稳定性,而无定形的内层则均匀了 Zn2+ 的传输,实现了均匀、致密的锌沉积。因此,双层 SEI 可在 4800 次循环中实现可逆的锌镀层/剥离,平均 CE 为 99.95% (± 0.06%)。同时,Zn | |Zn 对称电池在 28.4 mAh cm-2 的面积容量下显示出超过 550 小时的耐用寿命,ZUR 高达 98%。此外,基于双层 SEI 功能化锌负极和不同正极的全锌电池在高 ZUR 下均表现出稳定的循环性能。
Robust bilayer solid electrolyte interphase for Zn electrode with high utilization and efficiency
Construction of a solid electrolyte interphase (SEI) of zinc (Zn) electrode is an effective strategy to stabilize Zn electrode/electrolyte interface. However, single-layer SEIs of Zn electrodes undergo rupture and consequent failure during repeated Zn plating/stripping. Here, we propose the construction of a robust bilayer SEI that simultaneously achieves homogeneous Zn2+ transport and durable mechanical stability for high Zn utilization rate (ZUR) and Coulombic efficiency (CE) of Zn electrode by adding 1,3-Dimethyl-2-imidazolidinone as a representative electrolyte additive. This bilayer SEI on Zn surface consists of a crystalline ZnCO3-rich outer layer and an amorphous ZnS-rich inner layer. The ordered outer layer improves the mechanical stability during cycling, and the amorphous inner layer homogenizes Zn2+ transport for homogeneous, dense Zn deposition. As a result, the bilayer SEI enables reversible Zn plating/stripping for 4800 cycles with an average CE of 99.95% (± 0.06%). Meanwhile, Zn | |Zn symmetric cells show durable lifetime for over 550 h with a high ZUR of 98% under an areal capacity of 28.4 mAh cm−2. Furthermore, the Zn full cells based on the bilayer SEI functionalized Zn negative electrodes coupled with different positive electrodes all exhibit stable cycling performance under high ZUR.
