- The goal of this work was to obtain information useful in the improvement of life and performance of alkaline secondary cells utilizing porous zinc electrodes. Toward this end, experiments designed to test predictions of the most sophisticated mathematical models of the porous zinc electrode were performed. This approach is based on the conviction that the surest way to realize a significantly longer-lived zinc electrode is through better understanding of the electrode gained through the interaction between modeling and model revision based on feedback resulting from experimental testing of the models. Experiments performed have emphasized determination of the potential distribution over the surface of a flat rectangular porous zinc electrode operated under conditions of severly limited convective flow, the determination of potential distribution and concentration variations over the surface of similar electrodes when operated under normal flow conditions, and the evaluation of OH/sup -/ depletion as a failure mode in zinc electrodes operated under conditions of severely limited convective flow. Results of the experiments and interpretations of them in terms of the appropriate models are given. 17 figures, 5 tables.
