An inexpensive and durable polymer electrolyte composition exhibiting high ionic conductivity even in the absence of water or a solvent, characterized by comprising a molten salt and an aromatic polymer having a carbonyl bond and/or a sulfonyl bond in the main chain thereof and containing a cation exchange group. The aromatic polymer is preferably an aromatic polyether sulfone having a specific structural unit and containing a cation exchange group, an aromatic polyether ketone having a specific structural unit and containing a cation exchange group, or an aromatic polyether sulfone block copolymer and/or an aromatic polyether ketone block copolymer, the block copolymers comprising a hydrophilic segment containing a cation exchange group and a cation exchange group-free hydrophobic segment. The polymer electrolyte composition containing the block copolymer as an aromatic polymer exhibits high structural retention even in high temperatures.
一种廉价耐用的聚合物电解质组合物,即使在无
水或无溶剂的情况下也能表现出高离子电导率,其特征在于该组合物由熔盐和芳香族聚合物组成,芳香族聚合物的主链上有一个羰基键和/或磺酰基键,并含有一个阳离子交换基团。芳香族聚合物最好是具有特定结构单元并含有阳离子交换基团的芳香族聚醚砜,具有特定结构单元并含有阳离子交换基团的芳香族聚
醚酮,或芳香族聚醚砜嵌段共聚物和/或芳香族聚
醚酮嵌段共聚物,嵌段共聚物包括含有阳离子交换基团的亲
水段和不含阳离子交换基团的疏
水段。含有芳香族聚合物嵌段共聚物的聚合物电解质组合物即使在高温下也能保持较高的结构稳定性。
