AN EVALUATION OF POTENTIALLY USEFUL SEPARATOR MATERIALS FOR NICKEL-CADMIUM (Ni-Cd) SATELLITE BATTERIES

摘要

An evaluation intended to determine the potential suitability and probable efficacy of a group of separator materials for use in nickel-cadmium (Ni-Cd) satellite batteries was carried out. These results were obtained using test pro cedures established in an earlier evaluation of other separator materials, some of which had also been used in experimental battery celis subjected to simulated use conditions.nThe properties that appear to be most important are:high electrolyte absorptivity, good electrolyte retention, low specific resistivity, rapid wett ability and low resistance to air permeation. Wicking characteristics and wet-out time seem to be more important with respect to the initial filling of the battery with the electrolyte.nWhile the properties of some of these materials indicate that they would be satisfactory, no specific conclusions can be drawn as to their actual effective ness without further testing after they have been subjected to simulated use conditions in experimental cells.
