- Аннотация: To establish the mechanism and to determine lithium transport parameters in the intercalation electrodes based on solid lithium-accumulating compounds, the kinetic models were used, allowing performing a joint analysis of data obtained via the application of the following methods: electrochemical impedance spectroscopy, cyclic voltammetry, pulse chronoamperometry, and chronopotentiometry. The models describe sequential steps of lithium transport into the surface layer and the bulk of the electrode material particles, including the accumulation of lithium in the bulk. Stages of lithium transport in the surface layer and bulk of intercalation material particles are of diffusion nature and differ from each other by characteristic time and diffusion coefficient D. Taking into account of this peculiarity, as well as an adequate assessment of the geometrical configuration of the intercalation system, allows to determine correctly the diffusion parameters of lithium transport.
