摘要
近年来随着社会的发展和科技的进步,锂离子电池已成为重要的主流动力电池之一。分别从溶剂和添加剂2个方面综述了基于LiPF6的锂离子电池电解液的发展现状,详细介绍了适用于锂离子电池电解液的溶剂和添加剂,应用于锂离子电池电解液的常用有机溶剂有碳酸酯类、醚类和羧酸酯类有机溶剂,添加剂以其作用目的区分,可分为SEI成膜添加剂、导电添加剂、稳定添加剂、控制水分和游离酸添加剂、抗过充添加剂、阻燃添加剂及浸润性添加剂等;展望了锂离子电池电解液的研究方向。
In recent years with the development of society and the advancement of technology,lithium-ion batteries have become one of the imporrtant mainstream batteries. Development status of the lithium-ion battery electrolytes based on LiPF6 were reviewed through the solvents and additives,and the solvents and additives used in the lithium-ion battery electrolytes were introduced.The solvents used in lithium-ion battery electrolyte are common organic carbonates,carboxylic acid esters,ethers and organic solvents,and so on. According to their functions,the additives could be divided into these categories： SEI forming improver additives,conductive additives,stabilizing additives,control-water and free acid additives,overcharge protection additives,flame retardant additives,wetting additives,and so on. The researches of the lithium ion battery electrolytes were prospected.
