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

The Ionic Conductivity of Crosslinking Film of Poly(β-carboxyethylmethylsiloxane)-PEO and LiCF_3SO_3 Complexes.

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。

The crosslinking films of poly(β-carboxyethylmethylsiloxane)—PEO and LiCF_3SO_3 complexes were prepared. The ionic conductivity of the poly(β-carboxy ethylmethylsiloxane)-Li^+ films was increased by complexing with PEO and that reached 10^(-5) S cm^(-1) at room temperature. And the effects of the molecular weight of PEO, content of PEO and crosslinking agent, concentration of LiCF_3SO_3, temperature on the ionic conductivity were investigated.
