| 中文摘要: |
| 水系锌离子电池具有安全性好，成本低，环境友好等优势，成为了新一代电化学储能设备的有力竞争者。但因锌负极的不稳定性，以及水所诱导的副反应使得水系锌离子电池的大规模应用被阻碍。采用不同的成膜电解液添加剂，可以构筑稳定的电极/电解液界面，既可以调节Zn2+的沉积，抑制枝晶的生长，减少死锌；也可以抑制析氢、腐蚀等副反应，稳定锌负极，提高锌负极的可逆性。不同类型不同结构的成膜电解液添加剂，其作用机理不同。从添加剂的分子结构出发，对盐类、腈类、磺酸类、氟代碳酸酯类、酰胺类、磷酸酯类及生物质等添加剂在锌负极界面的相关研究成果进行了介绍，对几种不同结构的电解液添加剂的作用机理做出了阐述和归纳。并对未来水系锌离子电池的发展做出了预测。 |
| 英文摘要: |
| Aqueous zinc ion batteries have become a strong contender for the new generation of electrochemical energy storage devices due to their advantages of good safety, low cost and environmental friendliness. However, the instability of the zinc anode and the side reactions induced by water have prevented the large-scale application of aqueous zinc ion batteries. Different film-forming electrolyte additives can be used to construct a stable electrode/electrolyte interface, which can regulate Zn2+ deposition, inhibit the growth of dendrites, and reduce dead zinc, as well as inhibit the side reactions, such as hydrogen evolution, to stabilise the zinc metal anode, and improve the reversibility of the zinc metal anode. Different types of film-forming electrolyte additives with different structures have different mechanisms of action. Starting from the molecular structure of the additives, the relevant research results of salts, nitrile, sulfonic acid, fluorocarbonate, amide, phosphate and biomass additives at the interface of zinc metal anode are introduced, and the action mechanisms of several electrolyte additives with different structures are elaborated and summarised. A prediction of the future development of aqueous zinc ion batteries is also made. |
