自Wright和Armand报道了有关聚醚-碱金属盐络合物的电导及其应用以来,高分子固体电解质已成为近几年来迅速发展起来的一种新型功能材料。由于它具有较高的离子电导率、可塑性强、电化学稳定性等优点,使它在全固态高能密锂电池及电化学元件的应用上显示出了很大的优越性,但线型PEO的高结晶度(>75％)导致PEO-碱金属盐络合物的室温电导率很低(～10~(-8)S·cm~(-1)),限制了它的使用范围。因此,对PEO进行各种改性,以提高电
Since Wright and Armand reported on the conductance of polyether-alkali metal salt complexes and their applications, polymer solid electrolytes have become a new type of functional material that has rapidly developed in recent years. Because of its high ionic conductivity, plasticity, electrochemical stability, etc., it makes all-solid-state high-energy dense lithium battery and electrochemical components of the application shows great advantages, but the linear PEO High crystallinity (> 75%) leads to very low room temperature conductivity (~10 -8 S · cm -1) for PEO-alkali metal salt complexes, limiting its use. Therefore, various modifications of PEO to improve electricity
