Charge transport and discharge mechanism in (PVC+KClO3) polymer electrolyte films

This paper presents results of the studies on ionic conductivity and transference number measurements on potassium chlorate (KClO3) complexed polyvinyl chloride (PVC) films prepared by solution-cast technique. Temperature dependence of ionic conductivity and transference number data indicated the dominance of ion-type charge transport in these specimens. The magnitude of conductivity increased with increase in the concentration of the salt and temperature. Using this (PVC+KClO3) electrolyte, solid-state electrochemical cells were fabricated and their discharge profiles were studied under a constant load of 100 kΩ. Several cell profiles associated with these cells were evaluated and are reported.
