-117-based IPMNC.
Figure 2.17 depicts measured cyclic current/voltage responses of a typical
IPMNC (scan rate of 100 mV/sec). As can be seen, a rather simple behavior with a
small hysteresis is obtained. Note that the reactivity of the IPMNC is mild such that
it does not show any distinct reduction or reoxidation peaks within
±
4 V, except for
a decomposition behavior at ~
1.5 V, where the extra current consumption is appar-
ently due to electrolysis. Overall behavior of the IPMNC shows a simple trend of
ionic motions caused under an imposed electric field.
