Nickel cadmium (NiCd) batteries are electrochemical devices that consist of a cadmium hydroxide negative anode and a nickel hydroxide positive cathode, capable of operating well at low temperatures, with a higher energy density and lifespan compared to lead acid batteries, but hindered by a memory effect and environmental concerns due to cadmium.
In this chapter, the principle of operation of nickel–cadmium batteries, their charge–discharge cycles, processes in the overcharge phase, self-discharge, memory effect, and failure modes are explained. Batteries using nickel negative electrodes are commonly called nickel-based batteries or simply nickel batteries.
Since Nickel-cadmium (NiCd) batteries have a higher energy density (50–75 Wh/kg) and have a better life (2000–2500 cycles), directly compete with lead acid batteries. They are suitable for uninterruptible power supply and generator start applications .
Although the battery discharge rate and battery temperature are an important variable for chemical batteries, these parameters have little effect in nickel–cadmium batteries compared to lead–acid batteries. Therefore nickel–cadmium batteries can be used at high discharge rates without losing their nominal capacity.
