本文研究了含羧基聚有机硅氧烷——PEO复合物与LiCF_3SO_3复合膜的离子传导性能。实验结果表明,利用PEO与含羧基聚有机硅氧烷复合的方法能进一步提高含羧基聚有机硅氧烷—Li~+固体电解质膜的离子传导性。此复合膜在室温下的离子导电率可达10~(-5)S cm~(-1)。本文还研究了复合膜中所用PEO的分子量、PEO用量,LiCF_3SO_3含量、交联剂用量及温度对复合膜离子传导性的影响。
In this paper, the ionic conductivity of carboxyl-containing polyorganosiloxane-PEO composites and LiCF_3SO_3 composite films was investigated. The experimental results show that the ionic conductivity of carboxyl-containing polyorganosiloxane-Li ~ + solid electrolyte membrane can be further improved by the combination of PEO and carboxyl-containing polyorganosiloxane. The ionic conductivity of this composite membrane can reach 10 -5 S cm -1 at room temperature. The effects of PEO molecular weight, PEO content, LiCF 3 SO 3 content, crosslinking agent dosage and temperature on the ion conductivity of the composite membrane were also studied.
