本研究藉由兩種混摻型高分子電解質去探討離子導電機制，其一是(PEO/LiClO4)雙離子系統，另一是(PEO/PSS-Li)單離子系統，分別在不同溫度下使用AC-Impendance，量測出離子導電度，並對離子導電度跟溫度關係用Arrhenius方程式以及Volgel-Tamman-Fulcher(VTF)方程式去做趨勢圖。鋰離子二次電池中的電解質，鋰離子移動方式，會對離子導電度大小及離子導電機制，或是其他電化學性質有所影響。
本研究也量測兩高分子電解質系統鋰離子遷移數，去了解鋰離子在離子導電度中的貢獻程度，還有使用DSC、TGA量測去了解材料的熱性質。最後使用線性掃瞄伏安法（linear sweep voltammetry,LSV）去量測氧化裂解電位（decomposition voltage），並組成半電池，作充放電測試
實驗結果顯示雙離子系統符合VTF方程式，其鋰離子移動方式，主要是靠PEO高分子鏈的擾動所造成;而單離子系統符合Arrhenius 方程式，其鋰離子主要是靠傳統離子晶格跳躍(activated ion hopping)理論去移動。同時也針對方程式畫出的趨勢圖結果，計算出活化能，結果顯示活化能跟離子導電度呈現反比關係。
對於單、雙系統，鋰離子遷移數量測結果，與離子導電度呈現正比關係。根據雙離子系統和單離子系統，並使用不同鹽類添加方式(鹽類溶解在電解液中)，所設計出的三份分系統PEO/LiClO4/LiPF6，EO/Li莫爾比等於24/1，其氧化裂解電位約為4.5 V(vs.Li/Li+)，在0.1C速度下充放電，電容值表現為150 mAhg-1

Two blend- baed polymer electrolytes system composed of poly(ethylene oxide) (PEO), lithium perchlorate (LiClO4) or poly(4-Styrene sulfonate) lithium salt (PSS-Li), with and without electrolytic solution were investigated.
The structure and electrochemical properties of the electrolytes thus obt- ained were systematically investigated by a variety of techniques including dif- ferential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy(FTIR), AC-impedance, lithium ion transference number, linear sweep voltammetry (LSV) and charge-discharge measu reements.
The temperature dependence of the conductivity was fit by the Vogel-Ta mman-Fulcher(VTF) equation or Arrhenus equation, indicating that the mechanism for ion conduction are dependent upon the high-amplitude segmental motion of the polymer host or traditional ion hopping theory.
The conductivities and the mechanism of polymer electrolytes system were affected by the motion type of lithium ion.
The experiment’s results have showed that the PEO/LiClO4 double-ion polymer electrolyte system follow the VTF equation and the PEO/PSS-Li single-ion polymer electrolyte system was fit by Arrhenus equation.And from the results of a parameter fit to the equation about lithium ion motion mechanism in which activation energy (Ea) was calculated. The Ea data with ionic conductivity were presented with an inverse relationship.
For dual and single ion system, the lithium ion transference number results with ionic conductivity were positively correlated. According to double-ion systems and single-ion systems, to use different ways to add lithium salt (salt dissolved in the electrolytic solution) and to desight new polymer electrolyte system PEO/LiClO4/LiPF6, EO/Li molar ratio of 24/1. The oxidation potential of new polymer electrolyte system is approximately 4.5 V (vs.Li/Li+), and the data of charge and discharge test, the final capacitor value is up to 150 mAhg-1 at a scan rate of 0.1C.
