Effect of temperature and charge stand on electrochemical performance of fiber Nickel–Cadmium cell

The effect of temperature and charge stand periods on the discharge capacity of Nickel–Cadmium (Ni–Cd) cell is investigated quantitatively. 15 A h Ni–Cd cells with NiOOH cathode and Cd anode were used as test system. The cells were charged in two step constant current modes up to 1.7 V, then stored...

Summary:The effect of temperature and charge stand periods on the discharge capacity of Nickel–Cadmium (Ni–Cd) cell is investigated quantitatively. 15 A h Ni–Cd cells with NiOOH cathode and Cd anode were used as test system. The cells were charged in two step constant current modes up to 1.7 V, then stored at different temperatures from–20 to 60°C for charge stand periods of 1 day, 7 days and 15 days and discharged at 1 С rate current until the cell voltage reached 1.0 V. Although the discharge capacity of these cells at and around room temperature i.e., 10 to 30°C is good, at temperatures below 0°C and above 40°C, the performance is poor. Also from 40 to 60°C, the discharge capacities decreased with charge stand periods due to self discharge and for sub ambient temperature decrease in capacity is minimal.
