摘　　要：评价了锂离子二次电池常用有机液体电解质对环境的影响.在其它条件相同的情况下,电解液中不同有机溶剂配比的不同,使得其对环境的影响值不同,碳酸乙烯酯和碳酸甲乙酯两种有机溶剂按不同比例混合,比例越大对环境影响越小.通过评价和分析两种有机溶剂对环境影响值的贡献率,可为二次电池研发者提供选择最优配比的方法.With the rapid development of the secondary battery industry, more and more attention has been pare to the environmental problems resulted from it. However, the associated assessment system in China is not complete. This paper is mainly to assess the environmental impact of the organic solvent in commonly used organic liquid electrolyte of a specific Lithium ion battery. Other things being equal, different ratios of organic solvents result in different environmental impact values. The two organic solvents, EC and EMC, are mixed in different ratios, and the greater the ratio is, the less impact the whole mixed solvent has on the environment. By assessing and analyzing individual environmental impact values of the two kinds of organic solvents, a method can be offered for the secondary battery developers to determine the optimal ratio of the electrolyte mixture.
