摘要:

将经过熔炼、锻造、打磨和抛光的金属Ni、Cu、Sn、In、Ti作为Zn负极的基底,制备了水系Zn离子电池。运用XRD、SEM、原位光学显微镜和电化学表征技术,分析了不同基底上的析氢速率、Zn在不同基底上的沉积/溶解行为、电偶腐蚀程度以及循环性能。结果表明,Sn和In不仅能够抑制Zn与基底之间引起的副反应,而且具有优异的亲Zn性能,但Zn在Sn基底表面沉积的形貌受Sn晶面的影响较大,In更适宜用作Zn负极的基底。

关键词: 基底, 改性Zn负极, 副反应, Zn枝晶, 水系Zn离子电池

Abstract:

This paper used metals (Ni,Cu,Sn,In and Ti) after smelting,forging,grinding,and polishing as substrates of Zn anode for aqueous Zn?ion batteries.In addition,the paper adopted XRD,SEM,in?situ optical microscope,and electrochemical characterization techniques to analyze hydrogen evolution rate in different substrates,Zn deposition/dissolution behaviors,galvanic corrosion,and cycling performance in different substrates.The results show that Sn and In can not only inhibit the side reactions caused by the contact between Zn and substrates,but also have excellent Zn?philic properties. However, the morphology of Zn deposition on Sn substrate surfaces is greatly affected by Sn crystal planes.In contrast,In is more suitable for the substrate of the Zn anode.

Key words: Substrates, Modified Zn anodes, Side reactions, Zn dendrite, Aqueous Zn?ion batteries
