The nickel–cadmium secondary battery contains NiOOH/nickel hydroxide as a positive active material, cadmium/cadmium hydroxide as a negative active material, and an aqueous solution containing potassium hydroxide as the main component as an electrolyte. Generally the charge-and-discharge reaction is shown in the following formulas 1, 2 and 3.
Nickel-cadmium systems Ni-Cd cell utilises nickel hydroxide as the positive active material, a mixture of cadmium and iron as the negative electrode material, and an aqueous alkaline OH as an electrolyte.
However, nickel–cadmium batteries are very attractive for many applications and their performance makes them superior for many conditions. Batteries with nickel oxyhydroxide positive electrode are very popular batteries with alkaline electrolyte.
The energy density of a typical nickel–cadmium cell is 20 Wh/kg and 40 Wh/L. The nominal voltage of the nickel–cadmium battery cell is 1.2 V. 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.
Batteries with nickel oxyhydroxide positive electrode are very popular batteries with alkaline electrolyte. The nickel electrode, which has layered structure, can be paired with cadmium, iron, zinc, metal hydride, and even hydrogen negative electrodes. Nickel–cadmium battery was invented in 1899 by Waldemar Jungner from Sweden.
Nickel-cadmium batteries are used for devices like phones, toys, and hand tools . Ni and Cd are used as electrodes, with the cadmium electrode having a higher capacity . Ni-Cd battery advantages consist of long cycle life, durability, good charge retention, excellent long-term storage, low maintenance, and flat discharge.

The first Ni–Cd battery was created by Waldemar Jungner of Sweden in 1899. At that time, the only direct competitor was the lead–acid battery, which was less physically and chemically robust. With minor improvements to the first prototypes, energy density rapidly increased to about half of that of primary batteries, and significantly greater than lead–acid batteries. Jungner experimented with substituting iron for the cadmium in varying quantities, but found the iron formulations to be wan…
