【摘要】：传统碳酸酯电解液在高压条件下会持续氧化分解,严重制约了高压锂电池的发展,因此需要结合绿色、安全、经济效益等因素,设计、合成并筛选新型的高压电解液。本文介绍了传统碳酸酯电解液的现状以及在高压条件下被氧化的主要因素,综述了新型碳酸酯类、腈类、砜类以及离子液体类等高压电解液的研究进展。阐述了电解液高压条件下的作用效果及机理,为改善电解液稳定性、降低粘度、提高电导率及安全性能等方面的研究提出方向,为实现高压电解液的工业化奠定基础。
[Abstract]:Traditional carbonate electrolyte will be continuously oxidized and decomposed under high pressure, which seriously restricts the development of high-voltage lithium battery. Therefore, it is necessary to design, synthesize and screen new high-voltage electrolyte combining green, safety and economic benefits. This paper introduces the present situation of traditional carbonate electrolyte and the main factors of oxidation under high pressure, and summarizes the research progress of new carbonates, nitriles, sulfones and ionic liquids. The effect and mechanism of electrolyte under high pressure conditions are expounded. The research direction of improving electrolyte stability, reducing viscosity, increasing electrical conductivity and safety performance is put forward, which lays a foundation for realizing industrialization of high voltage electrolyte.
