摘　　要：高电压尖晶石镍锰酸锂(LiNi_(0.5)Mn_(1.5)O_4)工作电压高达4.7 V,具有高的比能量和比功率,循环性能好,环境友好,有望成为下一代锂离子电池正极材料。然而,高电压下常规碳酸酯电解液容易氧化分解,造成电池容量降低,为了推进LiNi_(0.5)Mn_(1.5)O_4在商业化中的应用,各个研究组纷纷致力于开发高电压电解液。从导电锂盐,新型溶剂和电解液添加剂三个方面综述了与LiNi_(0.5)Mn_(1.5)O_4相匹配的电解液研究进展。High-voltage spinel LiNi0.5Mn1.5O4 is a promising candidate for a next generation lithium ion battery cathode material based on its high operating voltage(4.7 V.Li/Li+),high powder,high energy density,excellent cycling stability,and environment friendly.However,its commercialization is hampered by severe capacity fade due to traditional carbonate based electrolyte decomposition at high voltage.In the past few years,much research efforts have been carried out on the exploration of electrolytes.Research progress and prospects of electrolytes matched with LiNi0.5Mn1.5O4 including conducting lithiumsalts,organic solvents and additives are reviewed in this paper.
