Failure Mechanisms and Analyses of Sealed Batteries.
Abstract
Results of tear-down analysis of uncycled nickel-cadmium from four manufacturers are presented. Analysis of the electrolyte extracted from the cells shows that a significant amount of carbonate is present in cells which have not been cycled. Failure-analysis procedures have been developed for nickel-cadmium and silver-zinc cells. Loss of electrolyte was the major failure determinant in the silver-zinc cells which were analyzed. A possible mechanism by which loss of capacity can occur when carbonate is produced during cell operation is discussed. (Author)
