摘要

以合成的Li0.5Fe2.5-yAlyO4 (y = 0.6、0.8和1.0)为阴极，采用低速扫描阻抗谱(SEI)和循环伏安法(CVA)研究了锂电源的电化学参数。测定了锂离子源的能量特性和锂离子在阴极基体中的扩散系数。

Electrochemical properties of lithium power sources with cathodes by mixed spinel oxides Li2O-Fe2O3-Al2O3

The study of electrochemical parameters of lithium power sources with cathodes based on synthesized samples Li_0.5Fe_2.5-yAl_yO₄ (y = 0.6, 0.8 and 1.0) were performed by the methods of impedance spectroscopy (SEI) and cyclic voltammetry (CVA) at low speed scan. The energy characteristics of sources and diffusion coefficient of lithium into cathode matrix are determined.
