A Nickel Cadmium (NiCd) battery is a type of rechargeable battery that has been in use since around 1915. It is composed of a cadmium hydroxide negative anode plate, nickel hydroxide positive cathode plate, with a separator and a soluble electrolyte.
The largest nickel–cadmium battery ever built is a 40 MW unit in Alaska which was completed in 2003. It occupies a building the size of a football field and comprises 13,760 individual cells.
Active materials in nickel-cadmium cells (Ni-Cad) are nickel hydrate (NiOOH) in the charged positive plate (Anode) and sponge cadmium (Cd) in the charged negative plate (Cathode). The electrolyte is a potassium hydroxide (KOH) solution in concentration of 20–34 percent by weight pure KOH in distilled water. Figure 1. Nickel Cadmium aircraft battery
A nickel-cadmium cell has two plates. 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 nominal voltage of the nickel–cadmium battery cell is 1.2 V. The energy density of a typical nickel–cadmium cell is 20 Wh/kg and 40 Wh/L. 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.
The energy density of a typical nickel–cadmium cell is 20 Wh/kg and 40 Wh/L.
