本實驗我們使用單一有機溶劑碳酸乙烯酯做溶劑，與高分子聚合物聚丙烯腈調配高分子電解質，並加入α-Al2O3奈米顆粒製成奈米複合高分子電解質。藉由碳酸乙烯酯的高沸點以及高含量的聚丙烯腈讓電解質接近固態提升鋰電池安全性。
我們使用X-Ray粉末繞射、熱差分析、熱重分析、循環伏安法分析、交流阻抗分析以及電池充放電等不同方法研究電解質，與使用磷酸亞鐵鋰為正極，鋰金屬為負極所製成的電池。
實驗結果顯示電解質中摻雜奈米粒子能有效提高電解質導電度。實驗中我們參雜奈米粒子越多導電度越高。α-Al2O3的摻雜能降低界面間的阻抗，以及降低電解質結晶程度。聚丙烯腈含量多的電解質接近固態，在熱分析上顯示在高溫工作時的安全性。最後使用接近固態且導電度最高的奈米複合高分子電解質製成鋰電池，可以提升導電度以及降低界面阻抗，並能有效提升鋰電池蓄電量。

Nano-composite polymer electrolytes were prepared by mixing various amounts of poly(acrylonitrile) (PAN), ethylene carbonate, and α-Al2O3 nano-particles. Batteries using these nano-composite polymer electrolytes were assembled with lithium iron phosphate and lithium metal as electrodes. Both electrolyte and the battery were characterized by powdered x-ray diffraction, differential scanning calorimetry, thermogravimetry, cyclic voltammetry, AC impedance analysis and battery charger/ discharger. Adding α-Al2O3 nano-particles in polymer electrolytes can effectively increase the conductivity of lithium ion, reduce the crystalline phase of PAN, and the interface resistances between the electrolyte and the electrodes. The electrolyte becomes solid as more PAN is added. This can improve the safety and the charge capacity of the battery.
