The mechanism of anodic dissolution of lithium has been studied by many investigators around the world. Considered here in greater detail were the conditions for flow past a lithium electrode in a real water-lithium current source. A turbulent boundary layer is found to appear in a waterlithium cell on the anode, and the limiting current observed experimentally is significantly lower than the external-diffusion current. As a result of experiments that were carried out, it was established that the oxidation rate of lithium does not depend on its polarization, but is determined by the electrode clamping pressure, the temperature, the circulation rate, and the concentration of the electrolyte solution. In other words, the lithium dissolves under limiting-current conditions. An analysis of the results presented in other literature and here suggested that the rate of the lithium oxidation process is limited by the water transfer in the film.
