摘要：

Concentration changes which occur in porous zinc secondary electrodes during cycling have been measured. Changes occurring within cycles are similar to those postulated in the convective flow theory of zinc secondary electrode shape change (1). The drastic cumulative changes in concentration as cycling progresses predicted by the theory were not observed in the cells studied. Overpotential measurements taken during cell operation have been compared with values of concentration overpotential calculated on the basis of the observed concentration changes. Failure of the experimental overpotentials to correlate with the calculated values is discussed. © 1979, The Electrochemical Society, Inc. All rights reserved.
