Аннотация
The kinetics of LiFePO4 oxidation by hydrogen peroxide in aqueous alkaline medium is studied with the use of potentiometric determination of lithium concentration in solution during delithiation. It is demonstrated that the lithium transfer through the reaction-product layer is controlled by diffusion. The activation energy and the diffusion coefficient of the species transferred in the solid phase during the chemical reaction of oxidative delithiation are determined and the parameters of this processes are analyzed.
