Controlling factors in the dissolution kinetics of the Li electrode in aqueous LiOH were investigated. Electrode potential was measured upon application of a galvanostatic or triangular wave current. The following conclusions were reached: the anodic dissolution of Li is controlled by activation polarization below a certain critical current density, i/sub lim/; i/sub lim/ increases with electrolyte flow rate; electrode resistance is independent of flow rate; above i/sub lim/ the concentration of LiOH in the diffusion layer exceeds the saturation concentration by an amount sufficient to cause the precipitation of LiOH on the electrode surface, and this action causes the electrode potential to rise; the electrode resistance of the activation-controlled region is 4 x 10/sup -5/ ohm-m/sup 2/. 5 figures.
