本研究建立ㄧ膠態高分子電解質(Gel polymer electrolyte, GPE)，首先利用氧化還原聚合法合成聚醚二胺接枝聚丙烯腈的共聚高分子，並和聚醚二胺和 PEGDE進行反應，製備出含聚丙烯腈交聯型高分子電解質膜 (XANE)，以二甲基甲醯胺(DMF)為塑化劑，過氯酸鋰(LiClO4)為添加的鹽類而形成膠態電解質，應用於電雙層電容器上。本研究利用FT-IR 和1H NMR鑑定聚醚二胺接枝聚丙烯腈的共聚高分子結構；由SEM觀察含聚丙烯腈交聯型高分子電解質膜的表面型態；經由DSC結果可得知當添加聚醚二胺接枝聚丙烯腈共聚高分子，可降低膠態電解質的Tg。於電化學性質方面，此膠態電解質隨著聚丙烯腈及聚氧乙烯組成比例不同，離子傳遞能力也不相同，在聚丙烯腈對聚氧乙烯莫耳數比例為0.15時，可得到最高的離子導電度為7.6 ×10-3 S cm-1；在循環伏安法進行電化學穩定性測試可以發現穩定電位窗為2.1 V；在微拉伸測試中此膠態電解質能夠承受的極限應力可達8.7 Mpa 。
經拉曼光譜得知聚丙烯腈可增進鋰鹽解離程度之外若接枝在高分子上可形成一離子通道促進離子傳遞能力。另外聚氧乙烯在二甲基甲醯胺中有極佳的分散性，可避免聚丙烯腈鏈段的團聚。綜合上述，聚丙烯腈及聚氧乙烯都可有效地提高電雙層電容器的儲能表現。在組成對稱性二極式超級電容器，使用活化介相瀝青/石墨烯複合碳材為電極材料，工作電位2.1 V，在高比功率為10 kW kg-1 (~ 5 kW L-1)下，比能量可高達20 Wh kg-1 (~ 10 Wh L-1)。此外，此膠態電解質製作方法簡易，也具有良好的機械完整性，可應用在工業捲對捲製程也可形成可撓式電容，極具發展潛力。

A gel polymer electrolyte (GPE) consisting of polyacrylonitrile (PAN)-interpenetrating crosslinked polyoxyethylene (PEO) network, donated as XANE, as a host, dimethylformamide as a plasticizer, and LiClO4 as a electrolytic salt was utilized for electric double layer capacitors due to its stable potential window and good mechanical strength as well as chemical stability. The conductivity value of XANE GPE with a tuned AN/EO ratio were ranged from 3.54 to 7.55 mS cm−1, in which all XANE GPEs were higher than that of liquid-phase liquid electrolyte (LE) (1.60 mS cm−1). For capacitor application, the capacitance values at low currents (0.125 A g-1) of XANE GPE cells were ranged of 196.1 to 247.0 F g-1, for comparison, the LE cell delivered an capacitance value of 183 F g−1 at the same discharge rate. The XANE GPE cell has a maximum energy density of 37.7 Wh Kg-1 and maintained 20 Wh kg-1 at a high power of 10 kW kg-1 when using a high porosity carbon electrode derived from mesophase pitch activation.
