Abstract
Electrochemical properties of a zinc/PVA-KOH-H2O-Iodine/carbon cell have been investigated. In this cell, PVA-KOH-Iodine gel was used as electrolyte with PVA/KOH wt.% ratio of 60: 40 and PVA aqueous solution/Iodine ratio 2: 1, while zinc and carbon rods serve as electrodes. The cylindrical glass vessel of length 3.0 cm and of diameter 2.0 cm is used as a cell compartment. The current-voltage characteristics and open circuit voltage-time, charge voltage/current-time and discharge voltage/current-time studies are made. The open circuit voltage has been observed for 100 hours. It is found that the cell is stable and also rechargeable.
