本文报导尖晶石型ＬｉＭｎ２Ｏ４化合物的制备方法，用循环伏安法和交流阻抗技术研究了Ｌｉ／有机电解液／ＬｉＭｎ２Ｏ４电池的电化学行为，用分形理论首次考察和进一步讨论电极材料的阻抗行为随锂离子嵌入或脱嵌电极时的变化 The preparation method of spinel LiMn2O4 compound is reported in this paper. The electrochemical behavior of Li / organic electrolyte / LiMn2O4 battery is studied by cyclic voltammetry and AC impedance techniques. The fractal theory is used to investigate and further discuss the impedance behavior Lithium ion insertion or extraction of the electrode changes
