摘要: 水系锌金属电池由于其安全性高、低成本等优点,在电化学储能领域内具有广阔的前景。然而,锌负极在沉积/剥离过程中的副反应阻碍了实际应用。本实验通过简单的热处理调控锌金属的结晶学取向,探究了晶面取向对于电化学性质的影响。本实验将晶体化学与电化学相结合,从前沿研究出发设计综合实验,激发学生对科研的兴趣。

Abstract: Aqueous zinc metal batteries have promising potentials in electrochemical energy storage due to their inherent safety and low cost. However, their practical application is hindered by side reactions during Zn deposition/ stripping. In this experiment, we report a simple heat treatment to achieve preferred orientation of the Zn(002) plane in Zn foils. Then, the effect of this change on electrochemical properties is evaluated. This experiment is closely related to the cutting-edge research topics based on crystal chemistry and electrochemistry, which would greatly inspire students’ interest in scientific research.
