- 本文以高氯酸锂和聚甲基丙烯酸甲酯（PMMA）为原料制备凝胶电解质，采用单因素实验优化制备工艺，然后用刮膜法制备了凝胶电解质薄膜，并采用循环伏安法和交流阻抗法对其导电性进行了研究。结果表明，原料PMMA和高氯酸锂的最优用量分别为0.17 g/mL和0.16 g/mL，溶剂碳酸丙烯酯和二氯甲烷的最优体积比为1∶1，二氯甲烷挥发时间27 h，可得到最高电导率为2.32 mS/cm的凝胶电解质，且其电导率与温度基本呈线性关系。制备的凝胶电解质膜电阻为0.1599 Ω/cm2，电阻较小，导电性能良好。
- Abstract:
- In this paper, gel-electrolyte was prepared using lithium perchlorate and polymethyl methacrylate (PMMA), and the preparation technology was optimized by single-factor test. Then the film of gel-electrolyte was fabricated by blade coating technology, and the conductivity of which was investigated by means of cyclic voltammetry and electrochemical impedance spectroscopy. The results showed that the optimum contents of PMMA and lithium perchlorate were 0.17 g/mL and 0.16 g/mL, respectively. The optimum ratio of the volume about propylene carbonate and dichloromethane was 1∶1, and dichloromethane volatilization time was 27 h. The conductivity of the gel-electrolyte was linearly related to temperature, and the highest conductivity was 2.32 mS/cm. The prepared gel-electrolyte film had lower membrane resistance, which was 0.1599 Ω/cm2, showing a good conductivity.
