| Popis: | The impedance of operating NiCd cells in the frequency range 0.001 to 100 Hz is characteristic of mass-transport processes that occur in the cells. Two diffusion processes are observed in the impedance spectrum, at least one of which appears to involve solid-state diffusion in a surface film. The diffusion characteristics have a pronounced dependence on cell current, as well as some dependence on cell state-of-charge and operating temperature. The diffusion properties of the NiCd cell do appear to be sensitive to the changes in morphological or chemical structure of the active materials that can occur during use. (Author) |
