Relaxation characteristics of lithium ion batteries are analyzed based on nano/micro multiphase .fluids model. The numerical code based on implicit SOR scheme is developed and the numerical solutions of the relaxation characteristics are successfully obtained for various operating conditions. The comparisons between the numerical and experimental results in a commercial battery for PC are made in detail. They are in good agreement from the view point of engineering applications. Consequently, the validity of mathematical model and the numerical scheme can be confirmed. Furthermore, parametric study for the voltage at the end of relaxation is made, and we accumulate the understanding of the important design data to improve the performance.
