| 摘 要： | 金属钾由于具有较高的理论比容量、较低的电极电势以及低廉的成本等优点，用作电池负极近年来受到研究人员的广泛关注。然而，在电池循环过程中，金属钾与电解液间的界面副反应、不可控的枝晶生长以及体积波动等问题严重地阻碍了金属钾电池的发展。针对上述问题，研究人员提出了各种改进策略，如负极结构化设计、人工SEI界面修饰、电解质优化等。文章对近年来金属钾负极研究情况进行了简要的分析与总结，以期为金属钾电池的设计与开发提供参考。

| Abstract: | Potassium metal being used as battery anode has attracted considerable attention in recent years due to its high theoretical capacity, low electrode potential and low cost. However, the interface side reactions between potassium metal and electrolyte, uncontrollable dendrite growth, and volume fluctuations during the plating/stripping process have severely hindered the development of potassium metal batteries. To solve the above problems, various methods have been put forward, such as anode structuralization, artificial SEI interface and electrolyte optimization. In this paper, a brief analysis and summary are given about the research on potassium metal anode in recent years, which is expected to offer some references for its design and development. |
