Voltammetric studies of lithium deposition/dissolution on Pt and Mo ultramicroelectrodes have been carried out at various temperatures in 1M LiClO4/PC and PC+EC solutions. Due to the short exposure time at the lithium surface, the influence of the decomposition reaction of the solvents with the deposited lithium could be retarded by applying a high scan rate, and clear sigmoidal CVs were observed for the ultramicroelectrodes. Based on this evidence, the lithium ion diffusion coefficient and kinetic parameters for lithium deposition/dissolution were obtained. The temperature dependence of these kinetic parameters is also discussed.
