| Abstract: | The diffusion process in a host structure has been studied at constant current with the cells: RuO2 composite/ LiClO4PEO/Li and RuO2 powder/LiClO4PC/Li. The effect of grain size distribution and temperature has been investigated and the diffusion coefficient for Li in RuO2 calculated along with the diffusion activation energy (0.52 eV). Results show no intercalation of PC at 25°C. |
