高分子固体电解质是近年来开发的可用于全固态电池等方面的新型材料,它具有优良的成膜性和粘弹性等一般无机固体电解质所不具备的特点。但由于室温电导率很低,应用受到限制。为了改进这一点,已进行了许多研究,并取得了不少进展。目前改性聚氧乙烯(PEO)的室温电导率可达10~(-4)S·cm~(-1)。本文主要讨论提高高分子固体电解质性能的途径,其中大部分是关于PEO的化学和物理改性,例如共聚、共混和交联等,同时也介绍了非聚醚、非氧型及自电离聚合物,并对今后的发展前景作了简要探讨,
Polymer solid electrolyte is developed in recent years can be used for all-solid-state batteries and other new materials, it has excellent film-forming properties and viscoelastic general inorganic solid electrolyte does not have the characteristics. However, due to the low room temperature conductivity, the application is limited. Much research has been done to improve this and much progress has been made. At present, the modified polyoxyethylene (PEO) has a conductivity of 10 -4 S · cm -1 at room temperature. This article focuses on improving the performance of polymer solid electrolyte route, most of them are about chemical and physical modification of PEO, such as copolymerization, blending and crosslinking, but also introduced non-polyether, non-oxygen and self-ionizing polymer , And made a brief discussion on the future development prospects,
