The active material of the positive plate (anode) is Ni(OH) 4 and the negative plate (cathode) is of cadmium (Cd) when fully charged. The electrolyte is a solution of potassium hydroxide (KOH) with a small addition of lithium hydrate which increases the capacity and life of the battery.

The diagram shows a circuit that is suitable for discharging nickel-cadmium (NiCd) as well as nickel-metal-hydride (NiMH) batteries. It is simple and inexpensive, but the components must be matched to the number of cells the battery contains. As long as D2 lights, the battery is discharged via R4 and T1. When the battery voltage drops below a ... NICKEL-CADMIUM BATTERIES Nickel-cadmium alkaline batteries have gained respect as a very reliable, long life electrochemical system from their performance in (4-1) industrial starter and standby service and in the space program.
