本篇參考Hussey之實驗參數，以分子動力模擬的方法研究溶劑之種類(乙、苯、二氯甲烷)及其添加量(0、20、30、50 wt %)對於融鹽EMICl/EMIAlCl4導電性之影響，並與實驗值比較。此外，也探討濃度為2M時，三種融鹽(EMIBF4、EMICl/EMIAlCl4、EMITFSI)分別與乙混合後導電性之差異。
　　模擬結果顯示，隨著乙含量的增加，EMICl/EMIAlCl4之陰、陽離子的擴散係數、比導電度與自由離子機率也隨之增加，這是因為越多乙分子進入EMI+之第一配位殼層，抑制陰、陽離子之結合。EMI+周圍之AlCl4-配位數隨著乙含量之增加而遞減，其值介於4至9。當溶劑更換為二氯甲烷與苯時，陰、陽離子的擴散係數與比導電度均下降，其中以溶劑為苯時最低。自由離子生成之機率以溶劑為苯時最高，乙最低，這是因為苯的體積最大，使得陰、陽離子不易結合。EMI+周圍之AlCl4-配位數隨著溶劑體積的增加而減少，約為6至8個。
　　在2M乙溶劑中，若改變融鹽種類時，陰、陽離子之擴散係數與比導電度的相對大小為EMIBF4＞EMICl/EMIAlCl4＞EMITFSI，但自由離子生成機率並沒有明顯差異。

　Molecular dynamics simulation method, based on the experimental parameters of Hussey, has been used to study the influence of solvent (acetonitrile, benzene and dichloromethane) and it’s amount (0,20,30,50 wt %) on the ionic conductivities for molten salt 1-methyl-3-ethylimidazolium chloride
(EMICl)/EMIAlCl4, and compare with experiment. Moreover, the difference in conductivity for mixture of CH3CN with three types of salt (EMIBF4, EMICl/EMIAlCl4, EMITFSI) at a concentration of 2.0M was also discussed.
　The result shows that the diffusion coefficients of cation and anion of EMICl/EMIAlCl4 system, the specific conductivity and the free ion probability increase with the content of CH3CN. This is ascribe to the intervention of more CH3CN molecules into the first coordination sphere of EMI+ ion, which suppress the association of ions. The number of coordinating AlCl4- ions around EMI+ decreases with the increase of acetonitrile amount, with a value between 4 and 9. As the solvent is replaced by dichloromethane and benzene, both the diffusion coefficients and conductivity decrease. Among them, benzene gives the lowest values. The highest free ion probability is obtained as benzene is the solvent, but the lowest for acetonitrile. The reason lies on the bulkiness of benzene, whose intervention between EMI+ and AlCl4- making them more difficult to associate. The number of coordinating AlCl4- ions around EMI+ decreases with the size of solvent, with a value between 6 and 8.
　At 2M acetonitrile, the diffusion coefficients and the specific conductivity have the order: EMIBF4＞EMICl/EMIAlCl4＞EMITFSI, but the fraction of free ions is nearly the same.
