| Outline of Final Research Achievements |
Mathematical modelling of overvoltage relaxation and EIS response for batteries has been carried out by applying dual transmission line as an equivalent circuit of electrode for commercially available batteries. Derived functions were quite complicated. However, we succeeded to express the overvoltage relaxation after current interruption and the EIS spectra. For the EIS spectra, the increase of real part impedance at lower frequency range than 1 mHz was successfully obtained by applying dual transmission line model. For the overvoltage relaxation, we succeeded to obtain the accurate response within a 1 mV residuals for 10 minutes relaxation by simply connecting two dual transmission line in series.
