摘　　要：概述近年来高浓度电解液在锂电池体系中的应用及研究进展,包括锂离子电池、锂金属电池、锂氧电池和锂硫电池;展望高浓度电解液的发展趋势。适当的稀释剂作为共溶剂对高浓度电解液进行稀释,形成局部高浓度电解液,是一种高效的方法;开发低黏度氟代溶剂替代传统酯类及醚类溶剂,形成高浓度氟代电解液,能更好地匹配高能量密度电池体系。The application and research progress in high concentration electrolytes in lithium battery were reviewed,including Li-ion battery,lithium metal battery,Li-O 2 battery and Li-S battery.The development trends of high concentration electrolyte were described.The localized high concentration electrolyte formed by adding appropriate cosolvent dilution into high concentration electrolyte,which was an efficient method.Replacing traditional ester and ether solvents by the low-viscosity fluorinated solvents to form high concentration fluorinated electrolytes would match with the high energy density battery systems better.
