摘要
锂离子电池作为一种绿色能源,自问世以来,已广泛应用于各个领域。为进一步满足日常需求,研发更高能量密度的锂离子电池已成为必然趋势。高电压电解液作为锂离子电池的"血液",其研发是必不可少的一部分。总结了高电压电解液的研究现状,其中重点介绍了碳酸酯类高电压高浓度电解液,高电压电解液添加剂,新体系电解液如砜类、腈类、氟代碳酸酯类、离子液体,并讨论了各自的优势以及不足。最后,对未来高电压电解液的发展进行了展望。
For the past decades, lithium-ion battery as a green power has been widely applied in various fields, like portal electronics, electrical and energy-related grid, and thus, it is paramount to develop high energy density Li-ion battery to conform to daily requirements. It is essential to develop high voltage electrolytes which are considered as the blood of the lithium-ion batteries to achieve high energy and high power density. The recent research progress of high voltage electrolytes for lithium ion batteries was reviewed. The discussions were focused particularly on the merit and demerit of high concentration electrolytes, additives, sulfone, nitrile, fluorinated electrolyte and ionic liquid. Finally, the development trend of high voltage electrolyte was also described.
