摘要
从电解液的组成和功能添加剂两大方面,综合阐述了锂离子电池电解液的研究进展。在电解液组成方面,找到具有高的介电常数和能在石墨类电极表面形成有效SEI的有机溶剂,并且找到具有良好电导率、稳定电化学性能的电解质。而电解液功能添加剂方面,重点研究是找到改善电池安全性能的添加剂。
From two aspects including the composition of electrolytes and the safety performance,research progress of electrolytes for the Li-ion batteries was introduced.From composition aspect of the electrolytes,organic solvents that have high dielectric constant and can form effective SEI on the graphite electrode surface were found out.At the same time,electrolytes that have good conductivity and stable electrochemical characteristics were also found out.Aiming at the electrolyte functional additives,the key research was to find out suitable additives which can improve safety performance of the Li-ion batteries.
