The kinetics of the Li electrode in LiOH(aq) was investigated. Electrode polarization was measured by voltammetric techniques. Graphs show the following results: anodic limiting current density increases with flow rate; limiting current density depends on flow rate and bulk electrolyte concentration; and electrode resistance is weakly dependent on flow rate. An intuitive model of mass transport-limited dissolution appears to be substantiated. The following tentative conclusions were reached: an upper limit to the rate of discharge of a lithium--water battery anode will be set by the mass transfer limitations of the flow system, and not by the kinetics of the charge transport within any microscopic surface films on the anode; the resistance of the anode surface film in the linear polarization region is quite low and essentially independent of flow rate; the plane parallel electrode geometry results in as low an electrode resistance as any so far investigated and should be considered for automotive battery design. 3 figures.
