采用凝胶聚合物电解质的聚合物超电容器及其制作方法
摘要：
采用凝胶聚合物电解质的聚合物超电容器及其制作方法,属于电子器件技术领域。本发明采用凝胶聚合物电解质,该电解质是以聚偏氟乙烯或偏氟乙烯－六氟丙烯共聚物为基体的锂离子聚合物电解质。其制备方法是在丙酮中加入偏氟乙烯－六氟丙烯共聚物颗粒配成溶液,再将0.5～2M/L的锂盐的碳酸乙烯酯－碳酸丙烯酯溶液加入到上述溶液中,充分混合,制成凝胶聚合物电解质溶液;将凝胶聚合物电解质溶液分别涂覆在已制作好的聚吡咯聚合物电极I和聚甲基噻吩或甲基噻吩－甲氧基噻吩共混物的聚合物电极II的表面,然后进行组装。该超电容器的比电容高,可达25F/g,具有良好的环境稳定性和使用寿命,不漏液,且比液体电解质超电容器更容易组装,对环境无污染。
摘要（英）：

This invention adopts Gel polymer electrolyte which is Li ion polymer electrolyte with the multipolymer of polyvinyliene fluoride (PVDF) or vinylidene fluoride-hexafluoropropane as the substrate. Thepreparation method is to add the polymer particles of vinylidene fluoride-hexafluoropropane into acetone to a solution to be added by the solution of ethyl carbonate-propylene carbonate of Li salt 0.5-2M/L to fully mixed with the Gel polymer electrolyte solution which is coated separately on the surface of electrode 1 of prepared polypropyrrole or the surface of electrode of the polymer blend of poly methylthiophene, thereafter to be assembled. The said super capacitor is with high specific capacitance as high as 25f/g, and fine atmosphere stability and durable life time without leakage.
