Galvanostatic experiments were performed under constant total pressure to determine the dependence of Coulombic efficiency on system parameters such as reduced galvanic current density. The dependence of reduced total and corrosion currents and reduced total and galvanic currents on galvanic current is shown. The following conclusions were drawn: a Coulombic efficiency of 1.0 may be approached over a range of LiOH concentrations; unit Coulombic efficiencies are approached linearly with external cell current as the conditions of ''mechanical'' or ''transient'' passivation are approached; electrode polarization data indicate that energy losses due to the polarization of the Li electrode are small even at current densites where the Coulombic efficiency exceeds 0.9; hydrogen gas evolution at reduced galvanostatic currents below 1.0 results in enhanced convection of electrolyte near the Li anode. 3 figures, 1 table.
