Abstract

The impedance of the positive active material $LiMnO_2$ is measured by the changeable trend following the time. The charge capacities of single cell and each cells of four made with thin film prepared in the dry box are measured after measuring the impedance with the interval of 0, 24, 48 and 72 hours. In result, the impedance through the delaying time is not enhanced continuously as result of the time. The variation of capacity enhanced is not watched as the result of the delaying time that all together of the positive thin film and the reference is soaked in the solution of electrolyte of 1M PC $LiClO_4$. But it can be known to increase the discharge capacities as that the impeditive value is decrease.
