EZE-Skitan

Experiments were performed using plates with expanders Quebraco and EZE-Skitan. The resulting capacity curves, as a function of the time of oxidation or reduction, are presented in Fig. 7.7. Besides the plates subjected to oxidation or reduction, reference negative plates with the same expanders were left in the test cells with no hydrogen or oxygen attack. 

Quebraco disintegrates when attacked by hydrogen and even more rapidly under oxygen attack. EZE-Skitan reacts with H2 and O2, but the resulting changes in expander structme improve its activity and thus the capacity of the negative plate increases. 

Figure 7.8 presents the capacity curves for cells assembled with negative plates with different expanders. It is evident from the data in the figure that expanders Mimosa and Velex have but a weak effect on battery cycle life. SNK and especially EZE-Skitan and Quebraco, improve... 

Figure 7.9 shows the basic stnictural groups in Quebraco and EZE-Skitan [25].
