What type is Nickel Cadmium storage cell?

Nickel Cadmium Storage Cell is a Secondary cell.

Nickel-Cadmium battery

Waldemar Jungner of Sweden in 1899 created the first NiCd battery. This battery uses nickel oxide in its positive electrode (cathode), a cadmium compound in its negative electrode (anode), and potassium hydroxide solution as its electrolyte.

  • A nickel-cadmium battery converts chemical energy to electrical energy upon discharge and converts electrical energy back to chemical energy upon recharge.
  • In a fully discharged NiCd battery, the cathode contains nickel hydroxide [Ni(OH)2] and cadmium hydroxide [Cd(OH)2] in the anode.
  • Ni-Cd cells have a nominal cell potential of 1.2 volts (V).
