Abstract
Measurements are reported, we believe for the first time, of the time-domain response of humid zeolites of types Na-X, Na-Y and Ca-A, in the time range 100 µs to 103 s. The results show the presence of non-linear responses with respect to the amplitude of the applied step voltage and they also reveal strong discrepancies with respect to the frequency-domain response, but exact correlation is absent on account of the non-linearities mentioned above. The discharge currents at intermediate and long times are very different according to whether the measurements are taken in the humid atmosphere or in vacuum, the former data showing a strong rise before the final fall. This is very unusual behaviour and its significance is not yet understood. The importance of time-domain measurements in non-linear systems is stressed and the relevance of electrochemical energy storage is introduced.Keywords
