储能电池是人们未来生活中不可或缺的一部分。随着能源的不断消耗以及环境问题的严峻形势,使得人们开始不断关注研究新型的“绿色电池”。关于储能电池的研究正在不断的创新与发展,但电池的应用仍存在诸多问题。近些年,因为充电电池而发生的爆炸事故时常发生,电池的安全性能与电池的电解液有着密不可分的关系。离子液体作为新兴的电解液材料具有很好的发展前景。本综述围绕离子液体用于电解液的理论及实际可行性方面展开叙述。 Energy storage battery is an indispensable part of people’s future life. With the continuous con-sumption of energy and the severe situation of environmental problems, people begin to pay more attention to the research of new “green battery”. The research on energy storage battery is constantly innovating and developing, but there are still many problems in its application. In recent years, explosion accidents often occur because of charging batteries. The safety perfor-mance of batteries is closely related to the electrolyte of batteries. As a new electrolyte material, ionic liquid has a good prospect. This review focuses on the theoretical and practical feasibility of ionic liquids used in electrolyte.
由公式(3-1)可知电导率由离子液体的粘度δ、密度 d 、分子量 M W 、离子的大小和性质等决定 [11] [12] [13],电导率与粘度、体积成反比,与密度成正比 [14]。在室温离子液体(RTILS)中,离子主要以阴阳离子、离子对和中性粒子集团的形式存在。赵赫等人通过分析发现室温下电导率与烷基链长的倒数成线性关系 [10]。A. Noda等人以高导电性的聚合物电解质为目的,研究出室温熔融盐,其具有高离子导电性,同时在熔融盐中对乙烯基单体进行了原位聚合 [15]。
