Summary:•Diagnostics of diffusion process by impulse method.•Comparative study of diffusion diagnostics results under different impulses applied.•Analysis ofion diffusion of electrochemical sources. Currently, there is a number of impulse methods for evaluation of cells and batteries internal resistance. This work deals with the analysis and following calculation of diffusion process of cell. The study of the diffusion process is made after the end of the discharge/charging pulse when the electrochemical cells returns to equilibrium state.
