Nickel batteries have a positive electrode of nickel hydroxide and a negative electrode of cadmium.
Nickel batteries have a positive electrode of nickel hydroxide and a negative electrode of cadmium. They offer good resistance to electrical use as they can be left in a discharged condition for long periods without permanent damage and offer good performance in high ambient temperatures.
Typical cell voltage
Range is 1.2V
Nickel batteries are used for standby as well as a range of other applications including. in trains and for starting aircraft. They and are especially suited to electrically or mechanically arduous applications.
