In order to determine the mass transfer rate of Li through a metal foil electrode, a tungsten blue electrode doped with lithium has been developed for sensing the Li+ ion in an organic electrolyte. The electrode potential changed linearly with the logarithmic change in Li+ concentration in an organic electrolyte containing LiClO4. By sandwiching a test foil electrode of Ni or Cu a bipolar cell was constructed for the determination of Li mass transfer rate in the metal foil. The rate determined by this method showed good agreement with that obtained by potential step current measurement.
