摘要
锂离子电池高电压正极材料是近年来研究的热点,而与之相适应的高压电解液也成为了研究重点。介绍了碳酸酯类以及离子液体、氟代溶剂、腈类化合物、砜类溶剂和其他溶剂体系等新型溶剂体系高电压电解液的国内外研究现状,并通过量子化学计算理论介绍了高电压电解液的氧化机理,对高电压电解液研究进程中存在的问题作了简要评价。
Recently,the development of high-voltage electrolytes for lithium-ion batteries have attracted a great at tention,corresponding with high-voltage anode materials for Li-ion batteries. The discussions were focused on the develop- ment of carbonate-based electrolytes, new electrolytes based on ionic liquid, fluorinated, nitrile, sulfone solvents and other high-voltage electrolytes. The quantum chemistry calculation theory was also used to introduce the oxidation mechanism of high voltage electrolyte.
