摘要/Abstract

摘要： 电解液是锂离子电池关键技术之一，在正负极之间起着输送和传导电流的作用，是连接正负极材料的桥梁。它影响着电池的工作电压、能量密度和安全性能等。近年来随着正负极材料的技术进步，电解液为了实现与新材料的匹配，在组分上出现了很大变化，现有的锂电池电解液标准及相应的测试方法也需要进一步更新，才能实现产品的检验规范化和质量标准化。本文介绍了电解液的现状及发展趋势，分析了我国现有电解液相关标准的情况，并对新的电解液国标提出了建议。

关键词: 电解液, 锂离子电池, 检测方法, 标准

Abstract: Electrolyte is one of the key technologies of lithium-ion batteries. It plays a key role in conveying the lithium ions and current between cathode and anode, and affects the working voltage, energy density and safety performance of the battery. In recent years, with the development of cathode and cathode materials, the composition of electrolyte has changed a lot in order to match with the new materials. The existing standards and corresponding test methods of electrolytes need to be updated to realize the standardization of the product. This paper introduces the current situation and development trend of electrolyte, analyzes the current standards of electrolyte in China, and puts forward some suggestions for the new national standards of electrolyte.

Key words: electrolyte, lithium ion battery, test methods, standards
