Abstract
Electrochemical properties of a Zn/PVA+Iodine aqueous solution/carbon cell have been investigated. In this cell, PVA+Iodine aqueous solution is used as an electrolyte and zinc and carbon rods serve as electrodes. As a cell compartment the cylindrical glass vessels of length 3.0 cm and of diameter 2.0 cm are used. The discharge voltage-current, charge voltage/current-time and discharge voltage/current-time characteristics and open circuit verses time has been examined. The open-circuit voltages and short-circuit currents of cells are observed 1.4 volt and 5.14 mA respectively. 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 well stable and also rechargeable.
