When the nickel-cadmium battery was developed, the lead-acid battery was already existing, and the inventors clearly realized the advantages of nickel cadmium battery system.
Advantages are:
1. Potassium hydroxide (KOH) does (practically) not take part in the electrochemical reaction. Therefore:
- a. Spacing between electrodes can be minimized. This means low electrolyte resistance and suitability for extremely high current of loads.
- b. The freezing point of the electrolyte does hardly change. So there are no problems even at very low temperatures (-40°C).
- c. Electrolyte stratification does not occur, boost charging is always possible.
2. Corrosion of metallic parts is hardly observed. Plate supports and conducting elements are made of nickel. Consequence is that Nickel-cadmium batteries can be stored for practically unlimited periods without refreshing charges.
3. Hydrogen evolution does not occur at the equilibrium potential of the cadmium electrode.
Consequence is that Nickel-cadmium batteries can be made sealed.
