n is the time base in hours (h) for which the rated capacity is declared. The cell voltage of nickel-cadmium cells results from the electrochemical potentials of the nickel and the cadmium active materials in the presence of the potassium hydroxide electrolyte. The nominal voltage for this electrochemical couple is 1.2 V.
The actual voltage appearing at the terminal needs to be sufficient for the intended application. Typical values of voltage range from 1.2 V for a Ni/Cd battery to 3.7 V for a Li/ion battery. The following graph shows the difference between the theoretical and actual voltages for various battery systems: 3) Discharge Curve
In the charge/discharge reaction of the nickel-cadmium battery, the potassium hydroxide is not mentioned in the reaction formula. A small amount of water is produced during the charging procedure (and consumed during the discharge).
For a charging voltage higher than 1.45V/cell, the current is limited @ 0.1C5. It is the voltage per cell at which the discharge is finished. For Ni-Cd, it is recommended to select a low EOD voltage (e.g. 1.00 V per cell), irrespective of the discharge time. The number of cells is linked to the voltage window of the load.
It is therefore usual to specify that a nickel–cadmium battery in a PV system has a maximum DOD of 90%. Industrial nickel–cadmium batteries used in PV systems are normally of the open type designed for standby use at low discharge rates. They may be of the pocket-plate or fibre-plate type.
