由文獻得知，添加鋁鎳對於陰極材料LiMn2O4的充放電循環數有明顯提升。本實驗針對添加鋁鎳陰極材料的導電性質以及電化學性質作探討

　　陰極材料LiMn2O4電阻率在降溫過程中，溫度280K附近電阻率有陡昇的現象，隨著鋁、鎳離子添加量的增加，電阻率陡升的現象就慢慢消失了，而且電阻率會呈現先降低後增加的趨勢。

　　陰極材料LiMn2O4經過球磨處理後與退火處理後的粉末，利用交流阻抗分析，其電荷轉移阻抗與鋰離子擴散係數有明顯的不同。鋁、鎳離子添加的粉末LiNixMn2-xO4與LiAlxMn2-xO4利用交流阻抗分析，可發現電荷轉移阻抗呈現持平的現象，而鋰離子擴散係數與室溫電阻率呈現相反的趨勢。

　　Decreasing of the temperature causes the phenomenon which the resisitity arise suddenly near temperature 280K. That is the manganese spinel undergoes a phase transition between high -temperature cubic and low temperature orthorhombic phase. Substitution of manganese cause disappearance of the phase transition characteristic of a stoichiometric spinel and affects the conduction mechanism of the material.

　　The powder with ball milling has different electrochemical properties from it with annealing. The material LiMn2O4 doped with Ni2+ or Al3+ ion also shows the different electrochemical properties.
